8 Parameter Measurement Information

GUID-D733FEAB-50F5-41AA-A7A0-0A6E31ED4137-low.gif
RL = 167 Ω (0.9 V to 2.7 V) and RL = 450 Ω (3.0 V to 5.25 V) on the A side and 1.35 kΩ on the B-side
RT termination resistance should be equal to ZOUT of pulse generators.
CL includes probe and jig capacitance. CL = 50 pF when on the B-side.
All input pulses are supplied by generators having the following characteristics: PRR ≤ 10 MHz, ZO = 50 Ω, slew rate ≥ 1 V/ns.
The outputs are measured one at a time, with one transition per measurement.
tPLH and tPHL are the same as tpd.
tPLZ and tPHZ are the same as tdis.
tPZL and tPZH are the same as ten.
