QUICK START PROCEDURE
Figure 1. Demo Board Setup
Demonstration circuit 1763A is easy to set up to evaluate
the performance of the LTC2195 A/D converterfamily. Refer
to Figure 1 for proper measurement equipment setup and
follow the procedure below:
Setup
If a DC1371 PStache Data Acquisition and Collection
System was supplied with the DC1763A demonstration
circuit, follow the DC1371 Quick Start Guide to install the
required software and for connecting the DC1371 to the
DC1763A and to a PC.
DC1763A Demonstration Circuit Board Jumpers
The DC1763A demonstration circuit board should have
the following jumper settings as default positions: (as
per Figure 1)
J1 PAR/SER: Selects parallel or serial programming
mode. (default: serial)
Optional Jumpers:
J8 Term: Enables/Disables optional output termination.
(default: removed)
J5 ILVDS: Selects either 1.75mA or 3.5mA of output
current for the LVDS drivers. (default: removed)
J14 LANE: Selects either 1-lane or 2-lane output modes
(default:removed)NOTE:TheDC1371doesnotsupport
1-lane operation.
J15 SHDN: Enables and disables the LTC2195. (default:
removed)
J2 WP: Enable/Disables write protect for the EEPROM.
(default: removed)
Note: optional jumper should be left open to ensure proper
serial configuration.

DEMO MANUAL DC1763A
QUICK START PROCEDURE
Applying Power and Signals to the DC1763A
Demonstration Circuit
If a DC1371 is used to acquire data from the DC1763A,
the DC1371 must FIRST be connected to a powered USB
port and have 5V applied power BEFORE applying 3.6V to
6V across the pins marked V+and GND on the DC1763A.
DC1763A requires 3.6V for proper operation.
Regulators on the board produce the voltages required for
the ADC. The DC1763A demonstration circuit requires up
to 500mA depending on the sampling rate and the A/D
converter supplied.
The DC1763A should not be removed, or connected to
the DC1371 while power is applied.
Analog Input Network
For optimal distortion and noise performance the RC
network on the analog inputs may need to be optimized
for different analog input frequencies. For input frequen-
cies above 140MHz, refer to the LTC2195 data sheet for a
proper input network. Other input networks may be more
appropriate for input frequencies less that 5MHz.
In almost all cases, filters will be required on both analog
input and encode clock to provide data sheet SNR.
The filters should be located close to the inputs to avoid
reflections from impedance discontinuities at the driven
end of a long transmission line. Most filters do not present
50Ω outside the passband. In some cases, 3dB to 10dB
pads may be required to obtain low distortion.
If your generator cannot deliver full-scale signals without
distortion, you may benefit from a medium power amplifier
based on a Gallium Arsenide Gain block prior to the final
filter. This is particularly true at higher frequencies where
IC based operational amplifiers may be unable to deliver
the combination of low noise figure and High IP3 point
required. A high order filter can be used prior to this final
amplifier, and a relatively lower Q filter used between the
amplifier and the demo circuit.
Apply the analog input signal of interest to the SMA con-
nectors on the DC1763A demonstration circuit board
marked J3 AIN1 and J4 AIN2. These inputs correspond
with channels one and two of the ADC respectively. These
inputs are capacitively coupled to balun transformers
ETC1-1-13(leadfreepartnumberMABA007159-000000).
Encode Clock
NOTE: Apply an encode clock to the SMA connector on
the DC1763A demonstration circuit board marked J11
CLK+. As a default the DC1763A is populated to have a
single-ended input.
For the best noise performance, the ENCODE INPUT must
be driven with a very low jitter, square wave source. The
amplitude should be large, up to 3VP-P or 13dBm. When
using a sinusoidal signal generator a squaring circuit can
be used. Linear Technology also provides demo board
DC1075 that divides a high frequency sine wave by four,
producing a low jitter square wave for best results with
the LTC2195. Using band pass filters on the clock and
the analog input will improve the noise performance by
reducing the wideband noise power of the signals. In
the case of the DC1763A a band pass filter used for the
clock should be used prior to the DC1075. Data sheet FFT
plots are taken with 10-pole LC filters made by TTE (Los
Angeles, CA) to suppress signal generator harmonics,
non-harmonically related spurs and broadband noise.
Low phase noise Agilent 8644B generators are used for
both the clock input and the analog input.
Digital Outputs
The data outputs, data clock, and frame clock signals are
available on J1 of the DC1763A. This connector follows the
VITA-57/FMC standard, but all signals should be verified
when using an FMC carrier card other than the DC1371.
Software
The DC1371 is controlled by the PScope™ System Soft-
ware provided or downloaded from the Linear Technology
website at http://www.linear.com/software/.
To start the data collection software if PScope.exe, is in-
stalled (by default) in \Program Files\LTC\PScope\, double
click the PScope icon or bring up the run window under
the start menu and browse to the PScope directory and
select PScope.

DEMO MANUAL DC1763A
QUICK START PROCEDURE
If the DC1763Ademonstration circuit is properly connected
to the DC1371, PScope should automatically detect the
DC1763A, and configure itself accordingly. If everything is
hooked up properly, powered and a suitable convert clock
is present, clicking the Collect button should result in time
and frequency plots displayed in the PScope window. Ad-
ditional information and help for PScope is available in the
DC1371 Quick Start Guide and in the online help available
within the PScope program itself.
Serial Programming
PScope has the ability to program the DC1763A board
serially through the DC1371. There are several options
available in the LTC2195 family that are only available
through serially programming. PScope allows all of these
features to be tested.
These options are available by first clicking on the Set
Demo Bd Options icon on the PScope toolbar (Figure 2).
Figure 3. Demobd Configuration Options

• Off (Default): Selects offset binary mode
• On: Selects two’s complement mode
Sleep Mode: Selects between normal operation, sleep
mode:
• Off (Default): Entire ADC is powered, and active
• On: The entire ADC is powered down.
This will bring up the menu shown in Figure 3.
This menu allows any of the options available for the
LTC2195 family to be programmed serially. The LTC2195
family has the following options:
Randomizer: Enables data output randomizer
• Off (Default): Disables data output randomizer
• On: Enables data output randomizer
