DESCRIPTION

The PL133-47 is an advanced fanout buffer design for

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

tions. The PL133-47 accepts a reference clock input from

DC to 150MHz and provides 4 outputs of the same fre-

quency.

The PL133-47 is offered in a SOP-8L package and it offers

the best phase noise, additive jitter performance, and low-

est power consumption of any comparable IC.
