FS6131

Programmable Line Lock Clock Generator IC

1.0 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

2.0 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.

3.0 Applications

• Frequency synthesis

• Line-locked and genlock applications

• Clock multiplication

• Telecom jitter attenuation
