FS7145: 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.
特性- 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
|
应用- Precision frequency synthesis
- Low-frequency clock multiplication
| 终端产品- Laser beam printers (FS7145)
- Video line-locked clock generation
