SiTime Corporation I2C\/SPI Oscillators SiT3521AI-2C125-GX125.000000

The SiT3521 is a 1 to 340 MHz I2C/SPI programmable oscillator with ultra-low jitter, offering any-frequency programming in 1 Hz steps and digitally controlled oscillator mode with pull ranges up to ±3200 ppm and resolution as low as 5 ppt. It features integrated LDO noise filtering, 0.02 ps/mV PSNR, and supports LVPECL, LVDS, or HCSL outputs with programmable swing and common mode voltage. Operating from -40°C to 105°C, it is housed in a 10-lead QFN package measuring 5.0 x 3.2 mm, and is RoHS and REACH compliant. The part supports I2C address configuration via pins or factory programming, and operates at 2.5 V, 2.8 V, 3.0 V, or 3.3 V supply voltage.
