SIT3372AC-2E2-33NG155.520000

Oscillators Overview

The SiTime SIT3372AC-2E2-33NG155.520000 is a differential MEMS VCXO operating at 155.52 MHz with LVDS output. It features ±25 ppm frequency stability and operates on a 3.3 V supply within the -40°C to +85°C temperature range. The device utilizes DualMEMS temperature sensing and TurboCompensation technology for dynamic performance against thermal gradients, shock, and vibration. Integrated on-chip regulators filter power supply noise, removing the need for external LDOs. Factory programmability allows optimization of clock configurations without custom quartz lead times.
