SiTime Corporation I2C\/SPI Oscillators SiT3521AI-2C225-9E25.000000

The SiT3521 is a 1 to 340 MHz I2C/SPI programmable oscillator with a 5.0 x 3.2 mm 10-lead QFN package. It supports LVPECL, LVDS, or HCSL outputs, offers typical integrated phase jitter of 0.21 ps (12 kHz to 20 MHz), and operates from -40°C to 105°C. The device includes an integrated LDO for power supply noise rejection and supports in-system frequency programming with 1 Hz resolution or ±3200 ppm digital pulling at 5 to 94 ppt resolution. It is RoHS and REACH compliant, and operates with 2.5 V, 2.8 V, 3.0 V, or 3.3 V supply voltages. The part is designed for telecom, networking, and industrial applications requiring low jitter and dynamic performance.
