340 to 725 MHz I2C/SPI Programmable Oscillator

The SiT3522 is an ultra-low jitter, user programmable oscillator. This device is based on SiTime's Elite Platform™ that utilizes unique DualMEMS™ temperature sensing and TurboCompensation™ technology to deliver exceptional dynamic performance, making it:

  • Resistant to airflow and thermal shock
  • Resistant to shock and vibration
  • 卓越的电源噪声抑制

The device supports two in-system programming options:
1) Any-frequency mode to reprogram the clock output to any frequency between 340.000001 MHz to 725 MHz
2) Digitally controlled oscillator (DCO) mode to steer or pull the clock up to ±3200 ppm

Combined with wide frequency range and user programmability, this device is ideal for telecom, networking and industrial applications that require a variety of frequencies and operate in noisy environments.
