March 1997
CMOS Clock Generator Driver
Description
The Intersil 82C84A is a high performance
CMOS Clock Generatordriver 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-bythree counter and complete “Ready” synchronization and reset logic.
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.
All inputs (except X1 and RES) are TTL compatible over temperature and
