DAC
The evaluation board has an on board reconstruction DAC
(AD9752). This is placed only to facilitate testing and debug of
the board. It should not be used to measure the performance of
the ADC, as it will not accurately indicate the ADC performance.
The DAC output is available at SMB P1. It will drive a 50
load. Provision to power-down the DAC is at Pin 15 at the DAC.
PCB LAYOUT
The PCB is designed on a four-layer (1 oz. Cu) board. Compo-
nents and routing are on the top layer with a ground flood for
additional isolation. Test and ground points were judiciously
placed to facilitate high-speed probing. A common ground plane
exists on the second layer. The third layer has three split power
planes, two for the ADC and one for support logic. The DAC,
components, and routing are located on the bottom layer.
TROUBLESHOOTING
If the board does not seem to be working correctly, try the
following:
Verify power at IC pins.
Check that all jumpers are in the correct position for the
desired mode of operation.
Verify VREF is at 2.5 V.
Try running encode clock and analog inputs at low speeds
(
10 MSPS/1 MHz
) and monitor 574 outputs, DAC output,
and ADC outputs for toggling.
The AD9432 Evaluation Board is provided as a design example
for customers of Analog Devices, Inc. ADI makes no warranties,
