DEFINITIONS:

CL = Load capacitance: includes jig and probe capacitance.

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

Generator.

NOTE:

1. Pulse Generator for All Pulses: Rate

≤ 10MHz; tF ≤ 2.5ns; tR ≤ 2.5ns.

2. Pulse Generator for All Pulses: Rate

≤ 10MHz; tF ≤ 2ns; tR ≤ 2ns.

NOTES:

1. For tSK(o) OUTPUT1 and OUTPUT2 are any two outputs.

2. For tSK(b) OUTPUT1 and OUTPUT2 are in the same bank.

NOTE:

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

Disable-HIGH.
