Notes
:
8. High-frequency AC-parameters are guaranteed by design and characterization.
9. Deterministic jitter is measured with both K28.5 and 2

-1 PRBS data-pattern, measured at <f
MAX
. V
IN
= 10mV (20mVpp) RX, 100mV (200mVpp)
TX. See the “PRBS Discussion” section for more details on the K28.5 and 2
– 1 PRBS data pattern.
10. Random jitter is measured with a K28.7 character pattern, measured at <f
MAX
. V
IN
= 10mV (20mVpp) RX, 100mV (200mVpp) TX. See the “PRBS
Discussion” section for more details on the K28.7 PRBS data pattern.
11. Crosstalk is measured at the output while applying two similar differential clock frequencies that are asynchronous with respect to each other at
the inputs.
12. LOS is guaranteed to be chatter-free at f
