I have purchased an AD9912A evaluation board for prototyping and have come across a few discrepancies in the evaluation board schematic. I would like to use a crystal in position x3. It is suggested to add an inductor L4 in the schematic however L4 has no specified value as the user guide indicates. Additionally the user guide indicates to remove the 1Kohm pull down resistor from pin 31. In the schematic this is labeled as R6 but I believe it to be R2 looking at the board?
