SIT3372AI-1E3-30NH125.000000

Oscillators Overview

The SiTime SIT3372AI-1E3-30NH125.000000 is a MEMS Voltage-Controlled Crystal Oscillator (VCXO) operating at a nominal frequency of 125 MHz. It features LVPECL output signaling and requires a 3.0V supply voltage. The device utilizes DualMEMS temperature sensing and TurboCompensation technology for low-jitter performance in noisy environments. It supports programmable frequency stability and pull range, eliminating the need for external LDOs through integrated on-chip regulators.

Oscillators Feature Summary

• Integrates DualMEMS temperature sensing and TurboCompensation technology to resist thermal gradients, shock, and vibration.
• Includes multiple on-chip regulators that filter power supply noise, removing the requirement for dedicated external LDO components.
• Factory programmable for specific combinations of frequency, stability, voltage, output signaling, and pull range.

Oscillators Applications

• Telecommunications systems requiring precise clocking
• Networking equipment with high-speed data transmission needs
• Industrial applications operating in electrically noisy environments

Oscillators Procurement Notes

Verify the exact part number configuration against official SiTime documentation to ensure correct voltage, output type, and frequency specifications. Confirm that the LVPECL output and 3.0V supply requirements align with the target circuit design before procurement.

Oscillators Selection Notes

Select this component when low jitter and resistance to environmental stressors are critical. The integrated regulation simplifies board design by reducing external component count. Ensure the application can accommodate the LVPECL interface and 3.0V logic levels.

Oscillators Part Context

This model belongs to the SiT3372 Elite Platform series, which offers ultra-low jitter differential VCXOs ranging from 1 MHz to 220 MHz. The AI suffix indicates an extended industrial temperature range, suitable for demanding operational conditions beyond standard commercial limits.

Oscillators Replacement Considerations

Substitution requires matching the 125 MHz frequency, LVPECL output, and 3.0V supply. Verify pin compatibility and thermal compensation characteristics with alternative MEMS oscillators from other manufacturers if direct SiTime variants are unavailable.
