SIT3522数据表

The SiT3522 is an ultra-low jitter, user programmable oscillator which offers the system designer great flexibility and functionality. The device supports two in-system programming options after powering up at a default, factory programmed startup frequency:

  • Any-frequency mode where the clock output can be reprogrammed to any frequency between 340 MHz and 725 MHz in 1 Hz steps
  • 数字控制振荡器(DCO)模式,可以通过5至94个PPT(每万亿分别)分辨率来转向或拉动时钟输出的振荡器(DCO)模式。

用户在订购代码中指定设备的默认启动频率。通过I2C或SPI实现设备的用户编程。用户可以用工厂可编程选项或通过硬件引脚指定最多16个I2C地址,使设备能够与其他I2C设备共享I2C。
