AD9789 retimer setting for DCODIV=32

Dear All,

 

I am using the AD9789 in LVDS SDR mode with DCO clock = fDACCLK/32 (DCODIV = 010 in register 0x22). It looks so that the retimer table are not usable in that mode. The standard mode is DCODIV=16.

 

I have to configure the latency, DSC and SNC values. If I use the DCODIV=16 mode then the table works as expected, but in case of DCODIV=32 mode it has some strange behaviour and I get it not running for my timing (latency of data to frame pulse).

 

Please, can someone give me a few hints.

 

Thanks and kind regards

Sven
