DEFINITIONS:

CL = Load capacitance: includes jig and probe capacitance.

RT = Termination resistance: should be equal to ZOUT of the Pulse Generator.

NOTES:

1. Diagram shown for input Control Enable-LOW and input Control Disable-HIGH.

2. Pulse Generator for All Pulses: Rate

≤ 1.0MHz; tF ≤ 2.5ns; tR ≤ 2.5ns.

3. if VCC is below 3V, input voltage swings should be adjusted not to exceed VCC.
