SIT3372AI-1E2-28NG50.000000

Oscillators Overview

The SiTime SIT3372AI-1E2-28NG50.000000 is a differential MEMS Voltage-Controlled Crystal Oscillator (VCXO) operating at a nominal frequency of 50 MHz. It utilizes DualMEMS temperature sensing and TurboCompensation technology to ensure stability under thermal gradients, shock, and vibration. The device features an LVPECL output format and operates on a 2.8V supply voltage. It provides an Absolute Pull Range (APR) of ±120 ppm and maintains a frequency stability of ±50 ppm over the industrial temperature range of -40°C to +85°C. The component is housed in a compact 6-SMD, No Lead Exposed Pad package.

Oscillators Feature Summary

• Integrates DualMEMS temperature sensing and TurboCompensation for dynamic performance against environmental stressors
• Includes on-chip regulators to filter power supply noise without requiring external LDOs
• Factory programmable for specific frequency, stability, voltage, and pull range requirements

Oscillators Applications

• Telecommunications systems requiring low-jitter clock signals
• Networking equipment demanding high stability in noisy environments
• Industrial applications subject to thermal gradients and mechanical shock

Oscillators Procurement Notes

Verify that the specific ordering suffix matches the required electrical parameters, particularly the 2.8V supply voltage and LVPECL output configuration. Confirm the package type is 6-SMD with no lead exposed pad. Ensure the APR specification aligns with system design needs, as this variant supports ±120 ppm pull range. Cross-reference the part number with official SiTime documentation to confirm current production status and availability.

Oscillators Selection Notes

Select this component when a differential VCXO is required for applications needing frequency adjustability via voltage control. The integrated noise filtering eliminates the need for additional external components, simplifying the design. Consider this part for designs where space constraints favor surface-mount packages and where resistance to vibration and shock is critical for maintaining signal integrity.

Oscillators Part Context

The SIT3372AI belongs to SiTime’s Elite Platform family of MEMS oscillators. This series is engineered for ultra-low jitter applications across a wide frequency range from 1 MHz to 220 MHz. The AI suffix typically denotes specific performance or packaging variations within the broader SIT3372 product line, designed to replace traditional quartz devices with programmable alternatives.

Oscillators Replacement Considerations

Direct replacements must match the 50 MHz frequency, LVPECL output, and 2.8V supply voltage. Verify that substitute parts support the same ±120 ppm APR and ±50 ppm stability. Ensure the replacement component offers comparable immunity to thermal gradients and vibration through similar MEMS compensation technologies.
