SIT3372AC-1B3-33NE25.000000

Oscillators Overview

The SiTime SIT3372AC-1B3-33NE25.000000 is a differential MEMS voltage-controlled crystal oscillator (VCXO) operating at 25 MHz with LVPECL output signaling. It functions within a supply voltage range of 2.97 V to 3.63 V and supports an operating temperature range from -40°C to +85°C. The device utilizes DualMEMS temperature sensing and TurboCompensation technology for dynamic performance stability against thermal gradients, shock, and vibration. Integrated on-chip regulators filter power supply noise, removing the need for external LDOs. The component is housed in a 6-SMD, no-lead package.
