SIT3372AI-2B3-28NE51.200000

Oscillators Overview

The SIT3372AI-2B3-28NE51.200000 is a differential MEMS Voltage-Controlled Crystal Oscillator (VCXO) manufactured by SiTime. It operates at a nominal frequency of 51.2 MHz with an LVDS output signaling format and requires a 2.8V supply voltage. The device utilizes DualMEMS temperature sensing and TurboCompensation technology to deliver ultra-low jitter performance while providing resistance to airflow, thermal gradients, shock, and vibration. Integrated on-chip regulators filter power supply noise, removing the need for external LDOs. This programmable component is housed in a 6-SMD, No Lead package.

Oscillators Feature Summary

• Integrates DualMEMS temperature sensing and TurboCompensation technology for dynamic stability against environmental stressors such as thermal gradients, shock, and vibration.
• Features integrated on-chip regulators that filter power supply noise, eliminating the requirement for dedicated external Low Dropout (LDO) regulators.
• Provides factory-programmable flexibility for frequency, stability, voltage, output signaling, and pull range to optimize clock configurations.

Oscillators Applications

• Telecommunications systems requiring precise timing signals
• Networking equipment demanding low-jitter differential clocks
• Industrial applications operating in noisy or thermally variable environments

Oscillators Procurement Notes

Verify the specific ordering suffix to confirm the exact output format, supply voltage, and frequency tolerance required for the design. Ensure the selected variant matches the system's electrical interface specifications. Confirm the package type and reflow profile requirements during procurement to guarantee compatibility with manufacturing processes. Cross-reference the part number with official SiTime documentation to validate all technical parameters before finalizing orders.

Oscillators Selection Notes

Select this component when designing circuits that require a differential VCXO with ultra-low jitter and high immunity to mechanical and thermal disturbances. The integrated noise filtering simplifies the power architecture by removing external LDO dependencies. Consider the programmability features to tailor the pull range and stability to specific application needs without custom quartz fabrication delays.

Oscillators Part Context

This model belongs to the SiT3372 family of differential MEMS VCXOs from SiTime. The series covers a frequency range from 1 MHz to 220 MHz and supports various output formats including LVPECL, LVDS, and HCSL. The family is engineered for telecom, networking, and industrial sectors where reliable clock generation under harsh conditions is critical.

Oscillators Replacement Considerations

Substitute parts must match the 51.2 MHz frequency, LVDS output, and 2.8V supply voltage. Verify pinout compatibility and package dimensions (6-SMD, No Lead) for direct replacement. Check if alternative MEMS VCXOs offer comparable jitter performance and pull range capabilities.
