SiTime Corporation I2C\/SPI Oscillators SiT3521AC-2C2331GM100.000000

The SiT3521 is a 1 to 340 MHz I2C/SPI programmable oscillator with ultra-low jitter, designed for telecom, networking, and industrial applications requiring flexible frequency generation. It comes in a 10-lead QFN package measuring 5.0 x 3.2 mm, supports LVPECL, LVDS, or HCSL output standards, and operates from -40°C to 105°C. The device offers any-frequency programming in 1 Hz steps and digital frequency pulling with resolution as low as 5 ppt, featuring integrated LDO for power supply noise rejection and a typical integrated phase jitter of 0.21 ps (12 kHz to 20 MHz). It is RoHS and REACH compliant, Pb-free, halogen-free, and antimony-free.
