6 Parameter Measurement Information

TCA9517A Test Circuit
A. RL = 167Ω (0.9V to 2.7V) and RL = 450Ω (3.0V to 5.5V) on the A side and 1.35kΩ on the B-side
B. RT termination resistance should be equal to ZOUT of pulse generators.
C. CL includes probe and jig capacitance.
D. All input pulses are supplied by generators having the following characteristics: PRR ≤ 10 MHz, ZO = 50 Ω, slew rate ≥ 1 V/ns.
E. The outputs are measured one at a time, with one transition per measurement.
F. tPLH and tPHL are the same as tpd.
G. tPLZ and tPHZ are the same as tdis.
H. tPZL and tPZH are the same as ten.
