General Description
The CGS3311, CGS3312, CGS3313, CGS3314,
CGS3315, CGS3316, CGS3317, CGS3318 and CGS3319
devices are designed for Clock Generation and Support
(CGS) applications up to 110 MHz. The CGS331x series of
devices are crystal controlled CMOS oscillators requiring a
minimum of external components. The 331x devices pro-
vide selectable output divide ratio (and selectable crystal
drive level). The circuit is designed to operate over a wide
frequency range using fundamental model or overtone
crystals.
Features
s Fairchild’s CGS family of devices for high frequency
clock source applications
s Crystal frequency operation range:
fundamental: 10 MHz to 100 MHz typical
3rd or 5th overtone: 10 MHz to 85 MHz
s Programmable oscillator drive
s Selectable fast output edge rates
s Output symmetry circuit to adjust 50% duty cycle point
between CMOS and TTL levels
s Output current drive of 48 mA for IOL/IOH
s FACTCMOS output levels
s Output has high speed short circuit protection
s Basic oscillator type: Pierce
s Hysteresis inputs to improve noise margin
