Description
Fully compatible with FS6370 (EEPROM-based) and FS6377 (register-based) devices. Three on-chip PLLs with Reference and Feedback Dividers set by internal ROM look-up table Four independently programmable muxes and post dividers Selectable power-down of PLLs and shutdown of output clock drivers Tristate outputs for board testing Can be optimized for reference clock (instead of crystal) input 5V to 3.3V operation Commercial (FS6372) and industrial (FS6372i) temperature ranges
The FS6372 is a CMOS clock generator IC designed to minimize cost and component count in a variety of electronic systems. Three phase-locked loops feeding four muxes and post dividers provide a high degree of flexibility.
