Test Mode
The TEST input is a three level input. In normal system
operation, this pin is connected to ground, enabling the
CY7B9911 to operate as explained in the previous section (for
testing purposes). Any of the three level inputs can have a
removable jumper to ground or be tied LOW through a 100Ω
resistor. This enables an external tester to change the state of
these pins.
If the TEST input is forced to its MID or HIGH state, the device
operates with its internal phase locked loop disconnected, and
input levels supplied to REF 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
function based only on the connection of their own function
select inputs (xF0 and xF1) and the waveform characteristics of
the REF input.
Maximum Ratings
Operating outside these boundaries may affect the performance
and life of the device. These user guidelines are not tested.

Note
4. FB connected to an output selected for “zero” skew (i.e., xF1 = xF0 = MID).
