Note 1: Supply current measurements exclude I
Note 2: AC characteristics guaranteed by design and characterization.
Note 3: Measured by applying a pattern that contains 20µs of K28.5, followed by 5µs of zeros, then 20µs of K28.5, followed by 5µs
Note 4: Variation of bias monitor gain for any single part over the range of V
Note 5: Deterministic jitter measured at 4.25Gbps with a K28.5 pattern (00111110101100000101).
