SiTime Corporation I2C\/SPI Oscillators SiT3521AC-2C333-GE100.000000

The SiT3521 is a 1 to 340 MHz I2C/SPI programmable oscillator with ultra-low jitter, designed for applications requiring flexible frequency generation in noisy environments. It is packaged in a 10-lead QFN measuring 5.0 x 3.2 mm and supports LVPECL, LVDS, or HCSL output signaling. The device operates from -40°C to 105°C and features integrated LDO for power supply noise rejection with 0.02 ps/mV PSNR. It 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. The part is RoHS and REACH compliant, Pb-free, Halogen-free, and Antimony-free.
