signal. The AD9713B is terminated into 51 Ω to provide a

1 V p-p signal at the output (RC Output).

Output Data

The output data bits are latched with two 74LS574 latches

which drive a 40-pin connector (AMP p/n 102153-09). The

data and clock signals are available at the connector per the pin

assignments shown on the schematic of the evaluation board.

Data is latched on the rising edge of the encode clock.

Analog Input

Analog input signals can be fed directly into the device under

test input (AIN). The AIN input is terminated at the device with

a 62 Ω resistor to give a parallel equivalent of 51 Ω (62 Ωʈ300 Ω).

DAC Reconstruction

The AD9022 evaluation board provides an on-board AD9713B

reconstruction DAC for observing the digitized analog input
