SIT3372AC-2E9-28NE148.425750

Oscillators Overview

The SiTime SIT3372AC-2E9-28NE148.425750 is a differential MEMS Voltage-Controlled Crystal Oscillator (VCXO) operating at a nominal frequency of 148.42575 MHz. It utilizes LVDS output signaling and requires a 2.8V supply voltage. The component is housed in a 6-SMD, No Lead package with an exposed pad. Designed for low-jitter applications, it incorporates DualMEMS temperature sensing and TurboCompensation technology to ensure stability against thermal gradients, shock, and vibration.

Oscillators Feature Summary

• Integrates multiple on-chip regulators to filter power supply noise without requiring external LDOs
• Factory programmable for specific frequency, stability, voltage, output signaling, and pull range combinations
• Provides resistance to airflow, thermal gradients, shock, and vibration through DualMEMS and TurboCompensation technologies

Oscillators Applications

• Telecommunications systems requiring variable pullable frequencies
• Networking equipment operating in noisy environments
• Industrial applications demanding robust clock signals under dynamic conditions

Oscillators Procurement Notes
