DESCRIPTION

The PL135-37 is an advanced oscillator fanout buffer

design for high performance, low-power applications.

The PL135-37 accepts a fundamental crystal input of

10MHz to 40MHz and produces three LVCMOS out-

puts of the same frequency. The Output Enable

(OE) function can be used to tri -state the outputs.

The PL135-27 offers the best phase noise and jitter

performance and lowest power consumption of any

comparable IC.
