Monolithic crystal controlled CMOS oscillator in bare die form

Description
The 54ACT3301 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 54ACT3301
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
