TS3DV642: Part-to-part skew spec

Alan O

Part Number: TS3DV642

Hello,

My customer needs a 2:1 mux to switch 10x LVDS pairs (Dual OLDI) from 2 deserializer IC's running a PCLK rate up to 125 MHz. This would require 2x TS3DV642 devices (6x diff pairs each).

What is the part-to-part skew of TS3DV642?

Thanks,
Alan

we don't have part to part skew spec, it more depends on your layout and trace length match

Trace matching is a fixed delay and should be within 1 ps error, so I think the part-to-part skew is NOT negligible.

Can you please check the device prop delay variance over process corners (assume temperature and voltage are the same between parts).

Regards,

Alan

ok, I think you want to know the parts variation of Propagation Delay. Let me check if I can find the data since we inherite it from other group.

sorry, we can't find bench data any more.
