SIT3372AI-1E9-28NX80.000000

Oscillators Overview

The SIT3372AI-1E9-28NX80.000000 is a differential MEMS Voltage-Controlled Crystal Oscillator (VCXO) manufactured by SiTime. It operates at a nominal frequency of 80 MHz with an LVPECL output signaling format. The device requires a supply voltage of 2.8V and is housed in a 6-SMD, No Lead package with an exposed pad. This component is engineered for low-jitter applications and utilizes DualMEMS temperature sensing technology.

Oscillators Feature Summary

• Integrates on-chip regulators to filter power supply noise without requiring external LDOs
• Provides resistance to airflow, thermal gradients, shock, and vibration via TurboCompensation technology
• Factory programmable for specific frequency, stability, voltage, and pull range configurations

Oscillators Applications

• Telecommunications systems requiring precise clock synchronization
• Networking equipment demanding low-jitter signal generation
• Industrial applications operating in noisy or thermally variable environments

Oscillators Procurement Notes

Verify the complete part number against official SiTime documentation to ensure correct configuration parameters. Confirm that the 2.8V supply requirement and LVPECL output levels match the target system design. Check reflow profile specifications during manufacturing integration to prevent thermal damage to the MEMS structure.

Oscillators Selection Notes

Select this model when a differential VCXO with factory-programmable pull range is required. Ensure the application environment involves potential thermal gradients or mechanical stress where standard quartz oscillators may fail. Verify that the 80 MHz frequency aligns with the system's timing architecture and that the 6-SMD package fits the PCB layout constraints.

Oscillators Part Context

This component belongs to the SiT3372 family of ultra-low jitter differential MEMS VCXOs. The series supports frequencies from 1 MHz to 220 MHz and offers various output formats including LVPECL and HCSL. The AI suffix indicates a specific industrial-grade variant within the broader SiTime programmable oscillator portfolio.

Oscillators Replacement Considerations

Direct replacements must match the 80 MHz frequency, LVPECL output, and 2.8V supply voltage. Consider other SiT3372 variants with different pull ranges if system requirements change. Cross-model substitution requires verification of pin compatibility and thermal performance characteristics.
