Part Number: SN75DPHY440SS

Hi Sir,

Customer encountered the problem that their CLK output (DBCP/DBCN) no signal, but data works fine.

Could you please advise if there have any HW mistake or any setting incorrect?

Or share some tips how could we look into issue?

BTW, there MIPI CLK is coming with High speed mode.

Thanks,

George

I don't see an issue with the schematic. Would you please clarify the statement "BTW, there MIPI CLK is coming with High speed mode"?

Do you have a scope capture of both the clock input and the clock output?

Thanks

David

Hi David,

Thanks for checking the schematic, let me check about more from customer.

Also scope the data-in for the reference.

Thanks,
