Hi Team,

I saw another post mention that BC_FREQ_SELECT =25MHz have potential issue, may I know what kind of potential issue might cause?

my customer is using this setting and pass 10M cable length with 720P fps.

Thanks

1. for 4Gbps line rate, it is recommended to use 50Mbps bc for sync. mode.
2. for 2Gbps line rate, you can use 25Mbps bc for sync. mode.
the reason is that higher ref. clock can get better jitter performance for PLL, above two solutions are qualified in TI d/s.

regards,
Steven
