I have a problem in reset NCO phase of all channel ( include channel data path, main data path, 2 DAC) synchronize with sysref signal. Current mode used is :
+ JESD 204b. Subclass1. Mode1, Dual channel.
+ Sysref 1MHz continuous pulse,50% duty cycle
+ DAC freq : 9216 MHz
+ Channel_NCO freq : 1152 MHz
+ Board : AD917x-FMC-EBZ
+ Sysref :On, AC mode
As in data sheet, NCO can reset by sysref signal by setting bit 2 in register 0x131 for channel NCO and 0x113 for main NCO. But no thing happened. Is any setting need for auto reset NCO with sysref signal????
