I am trying to route the SYSREF signal to one of the CS bits of the AD9680 output.
I have configured the AD9680 to output 14 bits of data, and 2 CS bits, but I do not see the SYSREF on either bit.
The relevant register values are as follows:
0x58F : 0x8D (14 bits of data, 2 CS bits)
0x559 : 0x55
0x55A : 0x05
Can someone please shed some light on this?
