SiT3522 Datasheet (SiTime) - I2C/SPI Programmable Oscillator

SiT3522, I2C/SPI Programmable Oscillator

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
