OUTLINE DIMENSIONS
Dimensions shown in inches and (mm).
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 V
REF
is at 1.23 V.
Try running encode clock and analog inputs at low speeds
(20 MSPS/1 MHz) and monitor LCX821 outputs, DAC
outputs, and ADC outputs for toggling.
