CMOS Clock Generator Driver

FN2974

Rev 4.00

Sep 9, 2015

The Intersil 82C84A is a high performance CMOS Clock

Generator-driver which is designed to service the requirements

of both CMOS and NMOS microprocessors such as the

80C86, 80C88, 8086 and the 8088. The chip contains a crystal

controlled oscillator, a divide-by-three counter and complete

“Ready” synchronization and reset logic.

Features

• Generates the System Clock For CMOS or NMOS

Microprocessors

• Up to 25MHz Operation

• Uses a Parallel Mode Crystal Circuit or External

Frequency Source

Static CMOS circuit design permits operation with an external

frequency source from DC to 25MHz. Crystal controlled

operation to 25MHz is guaranteed with the use of a parallel,

fundamental mode crystal and two small load capacitors.

• Provides Ready Synchronization

• Generates System Reset Output From Schmitt Trigger

Input

• TTL Compatible Inputs/Outputs

• Very Low Power Consumption

• Single 5V Power Supply

All inputs (except X1 and RES) are TTL compatible over

temperature and voltage ranges.

Power consumption is a fraction of that of the equivalent

bipolar circuits. This speed-power characteristic of CMOS

permits the designer to custom tailor his system design with

respect to power and/or speed requirements.
