DS250DF410: Inter-pair Skew

Jim CHEN

Part Number: DS250DF410


Dear Team,

Do you know the inter-pair skew spec that my customer need to follow when using DS250DF410? 

What is the maximum value of the length difference between 4 main lanes?

Thank you.

Jim

    Each retimer channel is independent. As such, there is no real limit to the input inter-pair skew at the retimer level. The only system link limit is thus the skew tolerance at the downstream Physical Coding Sublayer block.

    In terms of channel-to-channel inter-pair skew contributed by the retimer, TI list a datasheet typical value of < 30ps

    Cordially,
