xapp592(SDI Interfaces with kintex-7 GTX Transceivers) rx_t_lock sign filter

    Now I have a design based on xapp592(SDI Interfaces with kintex-7 GTX Transceivers).  I need use the rx_t_lock
 
sign for windows software. But I found that before the SDI sign is locked, the rx_t_lock will set 1'b1 occasionally.
 
Now I need know how to filter rx_t_lock jitter before the SDI sign locked.

Hi @chensimin1990,

 

Which vivado version are you using? Are you seeing the issue with the reference design with 2013.4?

 

Regards,

 

Florent

HI @chensimin1990,

 

Could you try with the reference design from the xapp and with 2013.4? Do you also see rx_t_lock toggling?
