Description

The FS6131-01 is a monolithic CMOS clock genera-

tor/regenerator IC designed to minimize cost and compo-

nent count in a variety of electronic systems. Via the I²C-

bus interface, the FS6131-01 can be adapted to many

clock generation requirements.

The ability to tune the on-board voltage-controlled crystal

oscillator (VCXO), the length of the Reference and Feed-

back Dividers, their granularity, and the flexibility of the

Post Divider make the FS6131-01 the most flexible

stand-alone phase-locked loop (PLL) clock generator

available.
