Monolithic crystal controlled CMOS oscillator in bare die form

Description

The CGS3311 is a crystal controlled CMOS oscillator

requiring a minimum of external components and is

designed for Clock Generation and Support

applications up to 110 MHz. The device is highly

versatile, providing selectable output divide ratios,

multiple crystal drive levels and selectable rise and fall

timing options. The circuit is designed to operate over

a wide frequency range using fundamental model or

overtone crystals. The device is a direct electrical and

mechanical replacement for the obsolete CGS3311

produced by National Semiconductor.

Features:

Crystal frequency operation range:

? fundamental: 10 MHz to 100 MHz typical

? 3rd or 5th overtone: 10 MHz to 85 MHz

Programmable oscillator drive

Selectable fast output edge rates

Output symmetry circuit to adjust 50 duty cycle

point between CMOS and TTL levels

Output current drive of 48 mA for IOL/IOH

Output has high speed short circuit protection

Basic oscillator type: Pierce
