DESCRIPTION

The PL133-97 is an advanced fanout buffer design for

high performance, low-power, small form factor applica-

tions. The PL133-97 accepts a reference clock input from

DC to 150MHz and provides 6 outputs of the same fre-

quency.

The PL133-97 is offered in a QFN-16L 3x3mm package

and it offers the best phase noise, additive jitter perfor-

mance, and lowest power consumption of any comparable

IC.

The PL133-97 outputs can be disabled to a high imped-

ance (tri-state) by pulling low the OE pin. When the OE pin

is high, the outputs are enabled and follow the REF input

signal. When the OE pin is left open, a pull-up resistor on

the chip will default the OE pin to logic 1 so the outputs are

enabled.

CLK8 is a free running output that remains enabled

when the OE pin is pulled low.
