DAC Reconstruction
The AD9040A evaluation board provides an onboard AD9721
reconstruction DAC for observing the digitized analog input
signal. The AD9721 is terminated into 51 ohms to provide a
1 V p-p signal at the output (RC OUTPUT).
Output Data
The output data bits are latched with a CMOS 74AC574 which
drives a 40-pin connector (AMP p/n 102153-9). The data and
clock signals are available on the connector per the pin assign-
ments shown on the schematic of the evaluation board. Output
data are available on the falling edge of the clock.
