Other Parts Discussed in Thread: DS32EL0421, DS32ELX0421

Hi TI expert

we're looking for a Serdes device to serialize/ De-serialize multiple LVDS inputs (4-5) into one output, the output will be connect to a fiber media, each LVDS input speed is up to 150Mhz, and the latency should be not more then few micro seconds,
can you please advise on such Device /Reference design?

Best regards,

Hi Thomas,

Could you provide a block diagram on what you want to achieve?

Is it 4 LVDS input to a single connection to 4 LVDS output where the single connection is fiber?

Best Regards,

Charley Cai

Hi Charley Cai

Following is the BD which described the required solution ( I guess need two Serdes's in each side):

Is there a clock signal along with the LVDS signals?

Our DS90UB947/948 device will need a clock signal to function.

Hi Charley Cai

we can generate a clock from the FPGA,
it seems the part DS90UB947 is mainly used for Video and Audio,
what about this one DS32EL0421?

Best regards,

Thomas

Hi Thomas,

Yes, DS32ELX0421 could work out as well. I may need to route you to a different team for DS32ELX0421
