Description
The FS6370 is a CMOS clock generator IC designed to minimize cost and ponent count in a variety of electronic systems. Three EEPROM-programmable phaselocked 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.
