Parameter Measurement Information

TCA9517 pmi_cps157.gif
RL = 167 Ω (0.9 V to 2.7 V) and RL = 450 Ω (3.0 V to 5.5 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.
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.
