RTC clock synchronization buffer driver delay chip

312.5MHz, ±50ppm, LVDS Ultra-Low Jitter Standard Differential Oscillator 6-QFM -40 to 85

The FS7140 or FS7145 is a monolithic CMOS clock generator/regenerator integrated circuit designed to minimize cost and component count in various electronic systems. Through the I2C bus interface, FS7140/45 can be adjusted according to various clock requirements. The length, fine-grained granularity of the reference and feedback dividers and the flexibility of the post-divider make the FS7140/45 the most flexible stand-alone PLL clock generator.
