FS714x

Programmable Phase-Locked Loop Clock Generator

1.0 Key Features

• Extremely flexible and low-jitter phase locked loop (PLL) frequency synthesis

• No external loop filter components needed

• 150MHz CMOS or 340MHz PECL outputs

• Completely configurable via I2C™-bus

• Up to four FS714x can be used on a single I2C-bus

• 3.3V operation

• Independent on-chip crystal oscillator and external reference input

• Very low “cumulative” jitter

2.0 Description

The FS714x (FS7140x or FS7145x) is a monolithic CMOS clock generator/regenerator IC designed to minimize cost and component

count in a variety of electronic systems. Via the I

2C-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 PLL clock generator available.

3.0 Applications

• Precision frequency synthesis

• Low-frequency clock multiplication

• Video line-locked clock generation

• Laser beam printers (FS7145)
