TEST POINT

CL = 30 pF

NOTES:

CL includes probe and jig capacitance

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

PRR â¤ 10 MHz, ZO = 50 â¦, tr â¤ 1.25 ns/V, tf 1.25 ns/V.

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

VTT = VREF = VDDQ x 0.5
