1 Timing is relative to the 0 differential voltage (VOD = 0).
2 LCR (link port clock ratio) = 1, 1.5, 2, or 4. tCCLK is the core period.
3 For the cases of tLCLKOP = 4.0 ns and tLCLKOP = 12.5 ns, the effect of tCOJT specification on output period must be considered.
4 LCR = 1.
5 LCR = 1.5.
6 LCR = 2.
7 LCR = 4.
8 The tLDOS and tLDOH values include LCLKOUT jitter.
9 TSW is a short-word transmission period. For a 4-bit link, it is 2 × LCR × tCCLK. For a 1-bit link, it is 8 × LCR × tCCLK ns.
