FS7140: I2C Programmable 1-PLL Clock _ BDTIC a Leading Distributor in China

FS7140: I2C Programmable 1-PLL Clock

The FS7140 or FS7145 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 FS7140/45 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 FS7140/45 the most flexible stand-alone PLL clock generator available.

Features

Extremely flexible and low-jitter phase locked loop (PLL) frequency synthesis
No external loop filter components needed
150 MHz CMOS or 340 MHz PECL outputs
Completely configurable via I2C-bus
Up to four FS714x can be used on a single I2C-bus
3.3 V operation
Independent on-chip crystal oscillator and external reference input
Very low cumulative jitter

Applications

Precision frequency synthesis
Low-frequency clock multiplication
