Datasheet Summary
1 to 340 MHz Elite Platform I2C/SPI Programmable Oscillator
Description
The SiT3521 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 re-programmed to any frequency between 1 MHz and 340 MHz in 1 Hz steps
- Digitally controlled oscillator (DCO) mode where the clock output can be steered or pulled by up to ±3200 ppm with 5 to 94 ppt (parts per trillion) resolution.
The device’s default start-up frequency is specified in the ordering code....
