SiTime Corporation I2C\/SPI Oscillators SiT3521AI-2C225-GS25.000000

The SiT3521 is a 1 to 340 MHz I2C/SPI programmable oscillator with a 5.0 x 3.2 mm 10-pad QFN package. It supports LVPECL, LVDS, or HCSL output types, offers ±3200 ppm digital frequency pulling with 5 ppt resolution, and achieves 0.21 ps typical integrated phase jitter from 12 kHz to 20 MHz. Operating temperature ranges from -40°C to 105°C for the extended industrial variant, with an integrated LDO for power supply noise rejection. The device is RoHS and REACH compliant, Pb-free, Halogen-free, and Antimony-free.
