Notes:
7.
The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established.
8.
Measured with 100mV input swing. See “Timing Diagrams” section for definition of parameters. High-frequency AC-parameters are guaranteed by
design and characterization.
9.
RJ is measured with a K28.7 comma detect character pattern, measured at 10.7Gbps and 2.5Gbps.
10. DJ is measured at 10.7Gbps and 2.5Gbps, with both K28.5 and 223–1 PRBS pattern
11. Total jitter definition: with an ideal clock input frequency of
≤ f
MAX, no more than one output edge in 10
12 output edges will deviate by more than
the specified peak-to-peak jitter value.
