SiTime Corporation Digitally Controlled Oscillators SIT3921AI-1D2-33NB100.000000

The SiT3921 is a digitally controlled differential oscillator (DCXO) offering output frequencies from 1 MHz to 220 MHz with factory-programmable accuracy. It supports multiple output standards including LVPECL and LVDS, and is available in industry-standard packages of 3.2 mm x 2.5 mm, 5.0 mm x 3.2 mm, and 7.0 mm x 5.0 mm. The device provides programmable pull ranges up to ±1600 ppm with linearity better than 1%, and exhibits less than 0.75 ps RMS phase jitter over a 12 kHz to 20 MHz bandwidth. Operating temperature ranges include industrial (-40 °C to +85 °C) and extended commercial (-20 °C to +70 °C). Supply voltage options are 2.25 V to 2.75 V or 2.97 V to 3.63 V. It features digital frequency control via a 40-bit protocol and meets MIL-STD-883F, JESD22, and MSL1 moisture sensitivity standards.
