Note 1: Supply current measurements exclude I
Note 2: Tested with R
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: V
Note 5: Variation of bias monitor gain for any single part over the range of V
Note 6: Guaranteed by design and characterization.
Note 7: Measured electrically with a 50Ω load AC-coupled to OUT+.
Note 8: Deterministic jitter is the peak-to-peak deviation from the ideal time crossings measured with a K28.5 bit pattern at 3.2Gbps
