SECTION 1.0 GETTING STARTED
1.1 Introduction
The SCMF Test Board is an assembled and tested PC Board
That demonstrates the Multiple Output and Single Output series of
reconfigurable oscillators.
The Test Board consists of a circuit board assembly with 6
SMA connectors, which allow frequency measurement of the 6
available outputs. The board can also interface with a microcontroller
through the I2C connector for reconfiguration of the oscillators.
With optional adaptor sockets, the 14 pin SMT multiple output
and the 8 pin SMT single output oscillators can be reconfigured.
Equipment supplied with the SCMF Test Board.
Software CD for creating JEDEC files for reconfiguration.
Required Equipment.
Compatible PC running Windows 98SE/ME/2000/XP
Optional Equipment
SC3600 Socket (used to measure and reconfigure the 8 pin Single Output
SMT oscillator)
SC3700 Socket (used to measure and reconfigure the 14 pin Multiple Output
Smt oscillator)

1.2 Software Installation
Insert the enclosed CD. If Setup does not auto start, then run
Setup from the CD.
This installation will install the JEDEC Creator program.

SECTION 2.0 JEDEC Creator
2.1 Running the JEDEC Creator Program
Note: If you do not wish to create JEDEC files you can skip this section and
proceed to the Using the SCMF Test Board.
From the desktop, click on the JEDEC Creator Icon.
The program can also be run by double clicking
JedecCreator.exe from the directory from which it was loaded
during installation.
The Options screen should now be visible.

Please select the type of part to be programmed and package type. Select OK
when ready.
The main screen should now be visible.

2.1.1 Entering PLL Frequencies
The first step is to enter a PLL frequency. Allowable PLL frequencies are
from 100 MHz to 400 MHz.
Note: The calculation of a PLL frequency is very complex. Not all
frequencies have solutions. If a PLL frequency cannot be calculated, an error
message will be displayed.
Suppose we need output frequencies of 155.52 MHz, 38.88 MHz,
53.125 MHz and 106.25 MHz. Since 155.52 MHz can be divided by 4 to get
38.88 MHz and 106.25 can be divided by 2 to get 53.125, we will be using
155.52 and 106.25 as our PLL frequencies. We can now enter PLL 1 as
155.52 and PLL 2 as 106.25. Enter these frequencies into the PLL1 and
PLL2 box and hit the Calculate button. Notice that as we enter new numbers
the Calculate button turns green indicating that we have made some changes.
The screen should look like this.

The OK in the Calculated Freq box indicates that the program has
found acceptable values for the PLL frequency and we can proceed to the
next step.

2.1.2 Selecting Divider Values
One of our desired output frequencies is 155.52 MHz. Lets
setup that frequency for Output A.
Under source for Clk A, click on the drop down box. A choice
of possible source frequencies are Ref, PLL1, PLL2, PLL3. The Ref
or Reference frequency can be used as a source instead of a PLL
frequency. The Ref frequency is determined at startup when the part
was selected. If you look at the Main Screen, you will see a number
next to the Part Type. This is the Ref Frequency for this setup.
Lets select PLL1 as the source for Clk A. Next lets select a
divider for Clk A. Since we want 155.52 as an output, our divider will
be 1. You can select divider values from 1 to 127. Click on the
Calculate button and the screen should look like this.

You have just setup Clk A for 155.52 MHz.
Lets setup Clk B. Since we want 38.88 MHz as Clk B, click
source B dropdown box and select PLL1. Click Divider B dropdown
box and select 4. Click the Calculate button. You have just setup Clk
B for 38.88 MHz.
Lets setup Clk C and Clk D.
Click source C dropdown box and select PLL2. Click Divider C
dropdown box and select 2.
Click source D dropdown box and select PLL2. Click Divider
D dropdown box and select 1.
Click the Calculate button.
The screen should look like this.

You are now ready to create the JEDEC file.

2.1.3 Saving the file to disc.
If all looks good it is time to save the file to disc.
From the File dropdown box, select Save As.
Enter a file name and click on the Save Button
The JEDEC file is now created.

SECTION 3.0 Using the SCMF Test Board.
3.1 Introduction
The SCMF Test Board is designed to measure and reconfigure
the Multiple Frequency Output and Single Frequency Output family
of oscillators from Cardinal Components.
The SCMF Test Board consists of the following basic
components.
The 6 test SMA connectors, which can be used for frequency
measurement.
The I2C connector, which can be used by a microcontroller for
reconfiguring the Multi and Single output oscillators using I2C
Protocol.
Onboard EEPROM for storing custom configurations for easy
reconfiguration of the oscillator.

3.2 Setting up the SCMF Test Board
3.2.1 Making measurement with the SCMF Test Board
Lets start by setting up the SCMF Test Board for frequency
measurement only.
When using the SCMF Test Board as a stand-alone unit, 5 Volts DC
must be applied to the board. Attach a cable from the SCMF Test
Board 5 Volt input to a 5 Volt DC source. Make sure that JP3 is
correct. See Figure 1 for details.
Figure 1

If 5 volts was applied to the board and JP3 is configured correctly, it
is time to install a part. Using the SC3600 adaptor socket for
measuring a Single Output part or the SC3700 adaptor socket if
measuring a Multiple Output part, insert the oscillator and adaptor
into the ZIF socket. Marked on the board at the SMA connectors are
the Clock outputs. There is also a Ref output. This output will be
active only on parts programmed for 6 outputs. If a single output part
is used, the output is always on Clk C. Refer to the appropriate
datashets for details.

3.2.2 Connecting the I2C interface
The SCMF Test Board has an I2C connection which can be used by a
microcontroller for reconfiguration and EEPROM access. The pin outs for
this connection are shown if Figure 2.
Please note: If there is a 3.3 volt source available, then the SClk,
SData, Gnd and VI2C (3.3 volts) can all be connected to the board through
the I2C connector. If this is the case, a 5 volt source is not needed and
jumper J3 must be in position 2 as shown.

Figure 2
3.2.3 Reconfiguring an Oscillator
Using the hex file created by the Jedec Creator program, the memory
address and data information can be programmed into the oscillator.
See Figure 3 for a typical hex file.
Figure 3

Reconfiguring the oscillator should be done in 2 blocks. The first
block is memory location 08hto 17hand the second block is memory
location 40hto 57h.Figure 3 shows a typical hex file with address and data
values. The address of the oscillator is D2h. Communication to the SCMF
Test Board uses the standard 2 wire Clk, Data Protocal.
3.2.4 Using the onboard EEPROM
The EEPROM on the SCMF Test Board is a 32K x 8 (256k bit)
Serial Electrically Erasable PROM. Writing and Reading to the
EEPROM is done in the same way as Writing to the oscillator. The
address of the EEPROM is ACh, (default) but can be changed by
jumpers JP5-JP7 (See EEPROM configuration chart below).

EEPROM Configuration Chart
The EEPROM can be used to store multiple
configurations. By doing a memory transfer from the EEPROM
to the oscillator, reconfiguration of the oscillator can easily be
achieved. The SCMF Test Board shows the ease of testing and
reconfigurating the Single and Multiple output family of
oscillators from Cardinal Components.
