INTRODUCTION
The MC145220EVK makes it easy to exercise features of the MC145220 and build PLLs which meet
individual performance requirements. The EVK is controlled through menu driven software operating on
an IBM PC or compatible. Other Motorola PLL EVKs (MC145190, MC145191, MC145192, MC145200,
MC145201, MC145202) in up to three–board cascades can use the same program. Frequency defaults
that apply to each are automatically selected. All board functions are controlled through the printer port of
an IBM PC. Up to three different EVKs may be controlled at the same time from one printer port. The
functional block diagram is given in Figure 1.
This manual is divided into three sections. Section 1 describes the hardware, Section 2 describes the
software, and Section 3 is the command summary.

GETTING STARTED
To perform basic functions, do the following:
1. Plug in 12 volts at J8, observing the polarity marked on the board.
2. Short circuit section 1 of the DIP switch (S1) and open circuit all other sections.
3. Connect the supplied flat cable between the computer printer port and the DB–25 connector on
the board (J9).
4. Type PLL at the DOS prompt. Then press enter.
5. Type the number that corresponds with the type of board given in the on–screen menu. The
MC145220 may operate in single loop or dual loop mode. Then press Q.
You should now see the main menu displayed. There should be a signal present at J5 if single loop, or
J12 if dual loop. The frequency will be the current output frequency given in the main menu. If the signal
is not on the correct frequency, check to see if your printer port address is $278 (hexadecimal 278). If not,
then select the P menu item and enter the correct address. After returning to the main menu, select the
I menu item to send data to the board. You should now be on frequency.
MODIFICATIONS
The user may modify the hardware, such as utilizing a different VCO, by using the prototyping area of the
board. After such modifications are made, the default values in the software may need to be changed.
This is facilitated from the ‘Select from the available options’ screen.
Note that the on–board voltage regulators allow for a maximum VCO control voltage range of 0.5 – 4.5
volts.

NOTES:
1. Supply current is current the board requires without user modifications.
2. Available current is the sum of currents available to the user (in the prototype area) from the 5 V and 8.5 V supply. The 12 V supply is not
regulated. Current at 12 V is limited by the external power supply. If the on–board VCO and amplifier are disconnected from the power bus,
more current can be drawn in the prototype area. The current flowing into U5 (the 8.5 V regulator) should not exceed 180 mA. This will limit
temperature rise in U5.
3. Frequency ranges require use of the 5 V default charge pump supply voltage.
4. VCO sidebands on PLL at low step sizes (10 kHz) are limited by control line leakage of the VCO. Up to 24 nA of leakage has been seen.
At higher step sizes (100 kHz and above), this effect is much less noticable. Thisdid not affect PLL′becauseits VCOleakage wasless than
10 pA.
5. 10 kHz phase noise is limited by the PLL device noise. For low noise designs, the loop bandwidth is made narrower and the VCO is relied
upon to provide the 10 kHz phase noise. This can be seen on the EVKs since the VCOs have much lower noise.
6. 10 MHz step, within ±1 kHz of final frequency (’220).
Due to the software architecture, when the user is measuring the switching time of a single board in dual loop mode, it takes 20 ms to load
the data as compared to single loop mode, which takes 8 ms to load the data. This is a limitation of the software, not the IC.
To find the actual PLL switching time, subtract 8 or 20 ms from the switching time stated in the table.

SUPPORT MATERIAL
The following documents are included in the appendix:
1. Schematic diagram of MC145220EVK.
2. Bill of materials.
3. Parts layout diagram.
4. Mechanical drawing of board.
5. MC145220 data sheet.
6. Typical signal plots.
PRODUCTION TEST
After assembly is complete, the following alignment and test is performed:
1. The control program is started in ’220 single loop mode.
2. [L]! is selected to set PLL frequency to 733 MHz.
3. Power is applied to the board. DIP switch section 1 is closed circuit with all others being open
circuit.
4. After attaching computer cable, [I]! is selected.
5. Trim resistor VR1 is adjusted to obtain an output frequency at J5 of 733 MHz ±500 Hz.
6. Voltage at the control voltage test point (TP2) is measured. It must be > 0.5 V.
7. [H]! is selected.
8. Voltage at the control voltage test point (TP2) is measured. It must be < 4.4 V.
9. [T]! is selected to toggle to PLL′.
10. [L]! is selected to set PLL′frequency to 790 MHz.
11. Voltage at the control voltage test point (TP9) is measured. It must be > 0.5 V.
12. [H]! is selected to set PLL′frequency to 820 MHz.
13. Voltage at the control voltage test point (TP9) is measured. It must be < 4.4 V.
14. [G] is selected and the board type is changed to ’220 dual loop mode.
15. [Q]!,then[I]!, isselected toinitializethedualmode output(J12) to70MHz. Thefrequency should
be 70 MHz ±50 Hz.
If in step 5 it isn’t possible to obtain a signal on frequency, the adjustment screw in M1 may be turned for
further frequency adjustment range. If neither adjustment works, [P] should be selected and the correct
printer port address entered. [I]! is then selected to reload the data.
BOARD OPERATION
A computer is connected to the DB–25 connector J9. Data is output from the printer port. The printer card
is in slot 0 using the default address in the control program. Data is sent to the PLL device (U1) through
the DIP switch (S1), and 74HCT241 buffer (U2). D1, D2, D3, R7, R8, and R12 are in the data path be-
tween the ’HCT241 and PLL device. This limits the high level output voltage of the buffer. Voltage on PLL
device inputs must be no greater than 0.5 V above V+. A ’220 PLL has three output lines which are
routed through a 74LS126 line driver (U3) back to the computer.
U2, the 74HCT241, provides isolation and logic translation for PLL input lines. Logic translation is need-
ed from the TTL levels on the printer port to the CMOS levels on the ’220 inputs.
A 12 V power supply should be used to power the board at J8 (Augat 2SV–02 connector). The 2SV–02
will accept 18–24 AWG bare copper power leads. No tools are needed for connection. If power is proper-
ly connected, LED D4 will be lit.

MOTOROLA
Power passes from J8 to U5 (LM317 regulator) configured as an 8.5 V regulator. 8.5 V powers the VCOs.
Regulators U6 and U7 use the 8.5 V supply to produce 3 V and 5 V. The ’220 board can use either to
power the logic and charge pump. V+ voltage is selected by J11. U6 and U7 are cascaded with U5 to
equalize their individual voltage drops.
The ’220 operates in both a single loop and dual loop mode. There are no component changes between
the two modes. The differences are in the programming of the counters and the SMA connector that is
used.
The PLL loop is composed of the MC145220 (U1), 733 – 743 MHz VCO (M2), and a passive loop filter
(R4, R5, C6, C7, C8). In single loop mode, output is taken from J5. A passive loop filter was used to keep
the design simple, reduce noise, and reduce the quantity of traces susceptible to stray pickup. The PLL′
loop is composed of the MC145220 (U1), 790 – 820 MHz VCO (M3), and a passive loop filter (R22, R25,
C24, C26, C30). In single loop mode, output is taken from J10.
Dual mode output is the (f′– f) frequency output from the mixer. It is low pass filtered (L1, L2, C15, C21,
C22) then amplified (U4). The output is available at J12.
Phase detector current is 2 mA. J1 is a removable jumper used for current measurement of V+.
Two TCXOs, a Motorola Saber 14.4 MHz (M5), and Raltron 10.01 MHz (M1) are supplied. As shipped
from the factory, the 10.01 MHz TCXO is in use. This allows both the 10 kHz and 10 Hz step sizes to be
used with one TCXO. 10.01 MHz cannot be divided for larger step sizes such as 100 kHz. For larger step
sizes use the Saber. Jumpers J3, J4, J13, and J14 determine which TCXO or the external reference
input is in use.
DUAL MODE OUTPUT
The dual mode output (J12) is the difference frequency from mixing PLL and PLL′. By using a reference
frequency of 10.01 MHz, PLL can be operated with a 10.01 kHz step size and PLL′with a 10 kHz step
size. If both PLL and PLL′step down in frequency, the mixed output will step up by 10 Hz. More informa-
tion on the offset reference technique is in AN1277/D, Offset Reference PLLs for Fine Resolution or
Fast Hopping. The block diagram, formulas, and an example are shown in Figure 2.

EXTERNAL REFERENCE INPUT
To use an external reference, disconnect J3, J4, J13, and J14. Use a reference signal at J2 which com-
plies with data sheet requirements. Then modify the reference frequency in the program main menu to
reflect the changes made (F menu item).
DATA TRANSFER FROM COMPUTER TO EVK
To control the serial input EVK with the parallel printer port, a conversion is done. Printer cards are de-
signed to output eight bits through eight lines. A bit mask is used to obtain the bit combination for the
three required output lines (Data, Clock, Load). As bytes are sent to the printer card in sequence, it ap-
pears to be a serial transfer. The printer port is used because data transfer using the serial port would be
much slower. A standard IBM PC can support a parallel port data rate of 4.77 MHz.
IBM PCs and compatibles can accept up to three printer port configurations. These ports are called
LPT1, LPT2, and LPT3. Each printer port has a unique address. Two sets of addresses are in common
use. One set applies to IBM PC XT, AT, and clones. The other is for the PS 2 line. To load data into the
EVK, the correct address must be selected. The program default is $278. If $278 is not the address in
use, it must be modified by entering the P menu item in the main menu. All allowed addresses given in
hexadecimal are as follows:
Label IBM PC and Clones PS 2
LPT1 278 3BC
LPT2 378 378
LPT3 3BC 278
Up to three EVK boards can operate independently from one printer port. All lines on the printer port are
connected to every EVK. Even with three boards operating, only three output lines (Clock, Data, and
Load) from the printer card are used. If two boards are controlled together, data for the second board is
received from the Output A of the first. Output A is a configurable output on ’220 devices, which in this
case is used to shift data through chip 1 into chip 2. Output A and Data are connected using a printer port
input line. This was done to avoid connecting extra wires. Fortunately not all port input lines are needed
for computer input. Load and Clock are common to both boards.
A three–board cascade is handled similarly to a two–board cascade. Out A on the first board is fed to
Data on the second. Out A on the second connects to Data on the third. Instructing the program on the
quantity of boards connected together allows it to modify the number of bits sent.
All boards have a DIP switch S1 which gives each a unique address. The configuration menu is used to
tell the program what type of board is connected at a board address. Switch positions for all possible
addresses are given in Figure 3.

Figure 3. Switch Positions
In Figure 3, DIP switch sections 6, 7, and 8 allow the computer to read Out A, Lock Detect′, or Lock
Detect from the PLL device. Each of the inputs can only be read on one board at a time, but each item
could be read on a different board. In a three–board cascade, Out A could be read from the first board,
Out B from the second, and Lock Detect from the third. There is no way to determine the board address
of a particular input with software. The control program does not make use of these inputs; however,
source code could be modified as required. Pin assignment on the printer port connector is:

PURPOSE
The user guide for the MC145xxx PLL software familiarizes the user with the use and capabilities of the
program referred from here on as PLLDEMO Version 4.0. The guide covers the user interface and a
summary of the commands that are available.
The user should read the data sheet of the PLL frequency synthesizer of interest before using the soft-
ware.
DESCRIPTION
The PLL software:
•is a Pascal program developed with Borland Turbo Pascal v7.0.
•runs under MS–DOS.
•is a character–based, menu–driven program.
USER INTERFACE
The user interface consists of numerous character–based, menu–driven screens which are displayed
below. Each screen is shown, along with a description of its purpose. Note that all screen shots shown
are a representative sample of the program. They are provided to familiarize the end user with the pro-
gram.
INSTALL
To install this program, create a directory called “PLLEVAL”. Change directories into “PLLEVAL” and
copy PLL.exe into this directory.

UNINSTALL
To uninstall this program, change directories into “PLLEVAL” and type “erase*.*”. After this command,
change out of directory “PLLEVAL” and type “erase PLLEVAL”.
Note: If you are in Windows 3.X or Windows 95, this program adds no entries into .ini or Registry files.
It is recommended that you have the PLL program running while you are reviewing this manual. Due to
the number of screens that may be involved in your evaluation, following the connections, screens, and
commands is easier when the manual and program are used together.
CONVENTIONS
Some of the PLLDEMO screens are necessarily “busy”. Because of this, the program follows several
conventions to help the user quickly absorb the screen information. These conventions are briefly de-
scribed on a help screen that is available throughout the program. Type the help command, [?], at any
time to view the help screen.
The conventions are as follows:
1. Command keys are surrounded by [ ]s. Type the letter between the [ ]s to execute the command.
[ ]s are followed by a description of the command.
2. [–] indicates a command not available to the user. Commands become available when they are
applicable to the currently targeted board.
3. [ ]s followed by an ! indicate the command will execute immediately. Otherwise a submenu is dis-
played from which further choices may be made.
4. Ifnochangesaredesiredtoaninputfield,leavethefieldblank.Thepreviousvaluewillthenbeused
forthat field.TypetheTAB keytomovetothenextinput field,or shift–TAB tomove tothepriorinput
field. Type RETURN to store the new input values while remaining on the same screen. Type Q to
store the new values and return to the prior screen.
5. Allnumbersareenteredasdecimalvaluesunlessotherwisenoted.A$followedbyavalueindicates
the value is in hexadecimal format. The output port address is in hexadecimal format.
6. The second line from the top of screen (screen title) states the purpose of the screen.
7. Screen information that can be changed by the user is displayed in bold or reverse video.
8. Commands are case independent. X is the same as x.
9. Frequencies are entered as two numbers, and displayed as one. The two input numbers represent
thedesiredfrequency inMHz, andinkHz.Theseinput valuesare addedtogetherto obtainthe final
frequency. Leave either input field blank to retain the prior value for that portion of frequency.
ALERT AND ERROR MESSAGES
This program contains two types of messages that appear when conditions warrant. (See Table 2.)
1. AlertMessages.Thesemessagesalertyouthatthoughthecurrentvaluesarevalid,youareunable
tocontinuouslyincrementtheAandN counters.Hit anykeytoremovethesemessages andcontin-
ue with the program. There are some instances of the alert messages where you may have to hit
any key twice to remove the message.
2. Error Messages. These are messages that indicate you have selected conditions that are outside
of the valid parameters of the IC. After hitting any key to continue, the invalid parameters you se-
lectedwillchangeback tothedefaultparametersoftheprogram.Youmaythenenter anothervalue
to continue your evaluation. There are some error messages where you may have to hit any key
twice to remove the message.

SCREENS
‘Define boards to program’
The first screen the user sees when the program begins has a screen title of ‘Define boards to program’.
This screen is used to define which boards are connected to the LPT1 printer port of the computer. Refer
to the hardware setup section to determine how to cascade the evaluation boards.
This screen is also available from the main menu. The user may return to this screen by depressing [Q]
to change the boards that are connected to the computer.
The screen is divided into two sections. The upper section shows the current board type settings while
the lower section allows the user to define a board’s type and position in the cascade connection.
Notice the section labeled ‘Available Boards:’ shows three labels, one for each board that may be cas-
caded. When the program first starts up it shows ‘N/A’ (not applicable) after each label. The user must
enter the boards contiguously. Initially the program requests for the user to enter board A’s type. This is
signified by
A (in the screen below) being set to A. The user can the select the board type for board A by
typing the corresponding command.
Once board A’s type is selected,
A automatically increments to B and the process may be repeated.
Once all boards have been correctly defined, the user may select [Q] which sends default data to the
boards and continues to the next screen. NOTE: Before selecting [Q], the user should insure that the
DIP switch settings shown in Figure 2 are correct.
If a board is incorrectly identified, select the board that is not correctly defined by typing the correspond-
ing board letter ([A], [B], or [C]). The user may then reselect the board’s type. Once the board has been
identified, the user may select the letter ([A], [B], or [C]) of the board followed by [S] to change hardware–
dependent variables for that board.
[X] can be selected to exit the program completely. [?] can be selected to view the help screen.

‘Select from the available options’
This is the main screen of the program. This is where the user enters commands to demonstrate the
capabilities of the various boards connected to the computer. The title of the screen is ‘Select from the
available options’.
This screen is broken down into three sections:
‘Available Boards’
This section displays the board types that are connected to the computer. It also designates which
boardis thecurrently selected‘target’ board.This istheboardthatwillreceivethecommandsfrom
‘MC145xxx Commands’ section. This section also provides the ability to change the targeted
board. Type the target board command ([A], [B], or [C]) to target that particular board.
‘MC145xxx Commands’
Thissectionisfurtherdividedintothreesubsections.Eachsubsectioncontainscommandsthatcan
besenttothe‘target’boardtodemonstrateitscapabilities.Eachofthesecommandsisdescribedin
full in the Command Summary.
The first subsection, ‘MC145xxx Frequency Commands’, contains commands that are
used to modify the PLL frequency in some way. These commands are available for all pos-
sible target board types.
In the top line of this section, ‘Current Output Frequency is
70 MHz’ designates what the
frequency is for the currently targeted board. This value is dynamic.
On the lines below this,
60 MHz is the current setting for the default low frequency.
70MHz is thecurrentsettingforthedefaultmediumfrequency. 80MHzis thecurrentsetting
for the default high frequency.
The second subsection, ‘MC145xxx Additional Commands’, contains commands that
areusedtofurthermodify thecurrentlytargeted board.Thesecommandsalso workwithall
of the MC145xxx board types.
The third subsection, ‘MC145220 EVK – Single Specific Commands’, are only dis-
played when the MC145220EVK in single loop mode is the currently targeted board. This
section shows commands that are specific to this board. This is required since this board
contains the equivalent of two PLLs.
The command letter for ‘Set target PLL on board’ is [T]!. In single loop mode, the user may
toggle between PLL and PLL′on the MC145220EVK by using this command. Feedback is
giventothe userastowhetherPLLorPLL′will beaccessed.Seenearthe topofthescreen
