The specifications for parameters in this table are applicable only after any appropriate stabilization time has elapsed.

(2)

The propagation delay, tphase error, is dependent on the feedback path from any output to FBIN. The tphase error, tsk(o), and tsk(pk)

specifications are only valid for equal loading of all outputs.

A.

NOTES: . CL includes probe and jig capacitance.

B.

All input pulses are supplied by generators having the following characteristics: PRR

≤ 100 MHz, Z

O = 50 Ω, tr≤ 2.5 ns,

tf≤ 2.5 ns.

C.

The outputs are measured one at a time with one transition per measurement.
