I have some unused pins of AD9953. Can I have advice how to set these pins setting.
Here is unused pin of the design.
10pin - CRYSTAL_OUT
44pin - SYNC_IN
45pin - SYNC_CLK
47pin - PS0
48pin - PS1
CRYSTAL_OUT(10pin) and SYNC_CLK(45pin) are output pins. So, it should be open.
Another is logic input, so I think it should be tied to GND due to 100k resister.
If my understanding is wrong, please would you give me your advice for each pin setting??
Thanks and best regards,
