SIT3373AI-4B2-30NX250.000000

Oscillators Overview

The SIT3373AI-4B2-30NX250.000000 is a MEMS voltage-controlled oscillator (VCXO) manufactured by SiTime, operating at a nominal frequency of 250 MHz. It features HCSL output signaling and requires a 3V supply voltage. The device is housed in a 6-SMD, No Lead package. It utilizes DualMEMS temperature sensing and TurboCompensation technology to deliver low-jitter performance with resistance to thermal gradients, shock, and vibration. Integrated on-chip regulators filter power supply noise, removing the need for external LDOs.
