Via the I Cbus 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 Feedback 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.
