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
CHARGE INJECTION
NOTES:
1. Select is used with multiplexers for measuring IQDCII during multiplexer
select. During all other tests Enable is used.
2. Used with multiplexers to measure IQDCII only.
3. Charge Injection =
VOUT CL, with Enable toggling for IQCII or Select toggling
for IQDCII.
VOUT is the change in VOUT and is measured with a 10M
probe.

DEFINITIONS:
CL = Load capacitance: includes jig and probe capacitance.
RT = Termination resistance: should be equal to ZOUT of the Pulse
Generator.
