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 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 PLL clock generator available.
