General Description
The FS6131-01 is a monolithic CMOS clock generator/regenerator IC designed to minimize cost and component 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.

KEY FEATUREs
• Complete programmable control via I2C™-bus
• Selectable CMOS or PECL compatible outputs
• External feedback loop capability allows genlocking
• Tunable VCXO loop for jitter attenuation

APPLICATIONs
• Frequency synthesis
• Line-locked and genlock applications
• Clock multiplication
• Telecom jitter attenuation
