SIT3372AI-2B3-25NY155.520000

Oscillators Overview

The SiTime SIT3372AI-2B3-25NY155.520000 is a differential MEMS Voltage Controlled Oscillator (VCXO) operating at a nominal frequency of 155.52 MHz. It features an LVDS output format and operates within a supply voltage range of 2.25 V to 2.75 V. The device provides a frequency stability of ±50 ppm across an extended industrial temperature range of -40°C to +85°C. Packaged in a compact 5.0 mm x 3.2 mm surface-mount footprint, it utilizes SiTime’s Elite Platform technology for low jitter performance.

Oscillators Feature Summary

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

Oscillators Applications

• Telecommunications systems requiring precise clock synchronization
• Networking equipment demanding low-jitter differential signals
• Industrial applications operating in noisy or harsh environments

Oscillators Procurement Notes

Verify the complete part number against official SiTime documentation to ensure correct configuration. Confirm that the ordering suffix matches the required voltage, output type, and stability specifications. Check regional availability as distribution status may vary by location. Ensure compatibility with system power rails and interface requirements before integration.

Oscillators Selection Notes

Select this component when a differential VCXO with LVDS outputs is required for high-frequency applications. Consider the ±50 ppm stability and -40°C to +85°C temperature range for industrial use. The integrated noise filtering simplifies board design by removing the need for external linear regulators. Verify that the 155.52 MHz frequency aligns with system timing needs.

Oscillators Part Context
