Datasheet Summary
340 to 725 MHz Elite Platform I2C/SPI Programmable Oscillator
Description
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
- 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.
A user specifies the device’s default start-up frequency in the...
