SiT3521 Product details

Description

The SiT3521 is an ultra-low jitter, user programmable oscillator which offers the system designer great flexibility and functionality. 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

Features

Programmable frequencies (factory or via I2C/SPI) from 1 MHz to 340 MHz.
Digital frequency pulling (DCO) via I2C/SPI.
Output frequency pulling with perfect pull linearity.
13 programmable pull range options to ±3200 ppm.
Frequency pull resolution as low as 5 ppt (0.005 ppb).
0.21 ps typical integrated phase jitter (12 kHz to 20 MHz).
Integrated LDO for on-chip power supply noise filtering.
0.02 ps/mV PSNR.
-40°C to 105°C operating temperature.
