EVALUATION BOARD
The FIFO provides all of the support circuitry required to
accept two channels of an ADC’s digital parallel CMOS outputs.
Each of the various functions and configurations can be selected by
proper connection of various jumpers (see Table 5). When
using this in conjunction with an ADC evaluation board, it is
critical that the signal sources used for the analog input and
clock have very low phase noise (<1 ps rms jitter) to realize the
ultimate performance of the converter. Proper filtering of the
analog input signal to remove harmonics and lower the integrated
or broadband noise at the input is also necessary to achieve the
specified noise performance.
See Figure 5 to Figure 15 for complete schematics and layout plots.
POWER SUPPLIES
The FIFO board is supplied with a wall mount switching power
supply that provides a 6 V, 2 A maximum output. Connect the
supply to the rated 100 ac to 240 ac wall outlet at 47 Hz to 63 Hz.
The other end is a 2.1 mm inner diameter jack that connects to
the PCB at J301. On the PC board, the 6 V supply is then fused
and conditioned before connecting to the low dropout 3.3 V
linear regulator that supplies the proper bias to the entire board.

When operating the evaluation board in a non-default
condition, J316 can be removed to disconnect the switching
power supply. This enables the user to bias the board
independently. Use P302 to connect an independent supply to
the board. A 3.3 V supply is needed with at least a 1 A current
capability.
CONNECTION AND SETUP
The FIFO board has a 120-pin (40-pin, triple row) connector
that accepts two 16-bit channels of parallel CMOS inputs (see
Figure 6). For those ADC evaluation boards that have only an
80-pin (40-pin, double row) connector, it is pertinent for the
lower two rows of the FIFO’s triple row connector to be connected
in order for the data to pass to either FIFO channel correctly.
The top or third row is used to pass SPI signals across to the
adjacent ADC evaluation board that supports this feature.
