2.0 Description
The FS6370 is a CMOS clock generator IC designed to minimize cost and component count in a variety of electronic systems. Three
EEPROM-programmable phase-locked loops (PLLs) driving four programmable muxes and post dividers provide a high degree of
flexibility.
An internal EEPROM permits just-in-time factory programming of devices for end user requirements.
