When using AD9176 in both single-link and dual-link mode therefore need two SYNCOUT signals.
The data sheet mentions possibility of combining two SYNCOUT signals in dual-link mode inside the DAC (register 0x110, bit 6); Will the combined SYNC signals be outputted on SYNCOUT0 or SYNCOUT1
Please provide additional information about combining the two SYNCOUT signals internally.
The two /SYNCOUTx signals are AND'd together, with an output at /SYNCOUT0.
Naturally if either link drops, both would have to be resynch'd.
Further to your response, wouldn't the /SYNCOUTx signals be "AND'd" together, not "OR'd", since these signals are active low; otherwise, when one link comes up, it's SYNC signal would mask any sync requests or error reporting of the other link. Could you please confirm that this is the case?
Hi Greg - Yes, fair point. AND is correct. I corrected the original answer.
