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 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.

Features

? Just-in-time customization of clock frequencies via internal non-volatile 128-bit serial EEPROM

? I2C? -bus serial interface

? Three on-chip PLLs with programmable Reference and Feedback Dividers

? Four independently programmable muxes and post dividers

? Programmable power-down of all PLLs and output clock drivers

? Tristate outputs for board testing

? One PLL and two mux/post-divider combinations can be modified via SEL_CD input

? 5V to 3.3V operation

? Accepts 5MHz to 27MHz crystal resonators

? ROM-based device available for cost reduction migration path – contact your AMI sales representative for more information
