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 Ω 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 that

drives a 40-pin connector (AMP p/n 102153-9). The data

and clock signals are available on the connector per the pin

assignments shown on the schematic of the evaluation board

(see Figure 10). Output data are available on the falling edge

of the clock.
