SIT3372AC-1E2-28NC156.250000

Oscillators Overview

The SiTime SIT3372AC-1E2-28NC156.250000 is a MEMS Voltage-Controlled Crystal Oscillator (VCXO) operating at a nominal frequency of 156.25 MHz. It features LVPECL output signaling and operates within a supply voltage range of 2.97 V to 3.63 V, typically powered at 2.8 V. The device exhibits a frequency stability of ±25 ppm and functions across an industrial temperature range of -20°C to +70°C. Packaged in a 7 mm x 5 mm surface-mount format, it integrates on-chip regulators for noise filtering.

Oscillators Feature Summary

• Utilizes DualMEMS temperature sensing and TurboCompensation technology for resistance to airflow, thermal gradients, shock, and vibration.
• Integrates multiple on-chip regulators to filter power supply noise, eliminating the need for dedicated external LDOs.
• Factory programmable for specific combinations of frequency, stability, voltage, output signaling, and pull range.

Oscillators Applications

• Telecommunications systems requiring low-jitter clock signals
• High-speed networking equipment
• Industrial applications operating in noisy environments

Oscillators Procurement Notes
