Via the I2C- bus interface, the FS714x can be adapted to many clock generation requirements. The length of the reference and feedback dividers, their fine granularity, and the flexibility of the post divider make the FS714x the most flexible stand-alone phase-locked loop (PLL) clock generator available.
