1:N LVDS/CML buffer from DC to 3Gbps

Other Parts Discussed in Thread: DS90LV001, DS25BR150, DS25BR204, SN65LVDS108

Hi team,

I'm looking for a 1:N fanout solution for LVDS and CML like below DS90LV001. It needs to be up to 3Gbps. I'm looking at DS25BR150, but it has internal termination that can't be parallel.

Thanks.

Hi Jerry,

You can use the DS25BR204 as a 1:4 repeater.

Thank you, I.K.

Customer needs up to 1:8 buffer. They would like to make channel-to-channel skew within 100ps. Do we have that part?

BTW, where can I find the .ami model for DS25BR204?

Thanks.

Hi Jerry,

The only 1:8 buffer we have is the SN65LVDS108, though it will only support data rates up to 400 Mbps. The skew also looks to be worse than the DS25BR204.

There is no .ami model available for the DS25BR204, only an IBIS model is available. AMI models are not created for LVDS parts.

Regards,

I.K.
