DESCRIPTION
The PL133-67 is an advanced fanout buffer design for
high performance, low-power, small form factor applica-
tions. The PL133-67 accepts a reference clock input from
DC to 150MHz and provides 6 outputs of the same fre-
quency.
The PL133-67 is offered in a TSSOP-16L package and it
offers the best phase noise, additive jitter performance,
and lowest power consumption of any comparable IC.
The PL133-67 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.
