PARAMETER MEASUREMENT INFORMATION (continued)

CL = 15 pF and includes instrumentation and fixture capacitance within ±20%.

The input pulse is supplied by a generator having the following characteristics: PRR

≤ 50 kHz, 50% duty cycle, tr ≤ 3

ns, tf ≤ 3 ns, ZO = 50Ω.

NOTE: PRBS bit pattern run length is 216

– 1. Transition time is 800 ps. NRZ data input has no more than five consecutive 1s

or 0s.
