Specifications subject to change without notice.

The CFS33xx Series utilizes

fundamental and 3rd overtone

crystal technology to provide

a low jitter output frequency.

The oscillator is equipped with

power saving standby feature

for battery and other low drain

applications. Available on

tape and reel in quantities of

500ea.

Clock Oscillator

With Standby Mode

Standby Feature: When pin 1 is disabled by applying a logic

"0", the output buffer of the oscillator goes into tri-state (high

impedance). In addition, the internal oscillator is stopped,

hence the entire oscillator consumes less than 10uA from

the supply pin.
