PI6C9911 & PI6C9911E

5V High Speed Programmable Skew

Test Mode

The TEST input is a three-level input. In normal system operation,

this pin is connected to ground, allowing the PI6C9911 to

operate as explained briefly above (for testing purposes, any of the

three-level inputs can have a removable jumper to ground, or be

tied LOW through a 100 ohm resistor. This will allow an external

tester to change the state of these pins).

If the TEST input is forced to its MID or HIGH state, the device will

operate with its internal phase locked loop disconnected, and in-

put levels supplied to REF will directly control all outputs.

Relative output to output functions are the same as in normal mode.

In contrast with normal operation (TEST tied LOW). All outputs

will function based only on the connection of their own function

select inputs (xF0 and xF1) and the waveform characteristics of the

REF input.
