PRODUCTION DATA
6 Parameter Measurement Information
Following load circuit is used to measure pulse duration, propagation delay, output rise-time and fall-time measurement.
Figure 6-1 Load CircuitA. Load resistance RL =
1 MΩ for measuring data rate, pulse width, propagation delay and output rise and
fall measurements. RL = 50 kΩ for measuring enable and disable
times.
B. RT termination
resistance should be equal to ZOUT of pulse generators.
C. CL Load capacitance
includes probe and jig capacitance. CL = 15 pF when on the B-side.
D. VEXT External voltage
for measuring switching times.
E. All input pulses are supplied by
generators having the following characteristics: PRR ≤ 26 MHz, ZO = 50 Ω,
slew rate ≥ 1 V/ns.
F. VCCI is the
VCC associated with the input port.
G. VCCO is the
VCC associated with the output port.
