DS110DF410 - Channel to Channel skew

Hello Kawai,

The intra-pair skew (i.e. between TXP and TXN for any output) is about 3 ps. The skew between two channels, for example between channel 0 and channel 1, is not a specified/tested parameter. Note that the propagation delay (a.k.a. latency) through the device from input to output at 10.3125 Gbps is about 300 ps. I expect the skew between two channels to be much less than the propagation delay through a channel, and more on the order of the intra-pair skew (few picoseconds). However, I should stress that this is not a tested or specified parameter. Hope this helps.

Best regards,

Casey Morrison
