SIT3372AI-1B2-33NZ135.000000

Oscillators Overview

The SiTime SIT3372AI-1B2-33NZ135.000000 is a differential MEMS Voltage Controlled Crystal Oscillator (VCXO) operating at a nominal frequency of 135 MHz. It utilizes LVPECL output signaling and functions with a supply voltage of 3.3V. The device is housed in a compact 6-SMD, No Lead package. Designed for low-jitter applications, it incorporates DualMEMS temperature sensing and TurboCompensation technology to ensure stability against environmental factors such as thermal gradients, shock, and vibration.

Oscillators Feature Summary

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

Oscillators Applications

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

Oscillators Procurement Notes

Verify the complete part number including suffix codes to ensure correct voltage, output type, and frequency specifications. Confirm that the LVPECL output level matches the receiving circuit requirements. Check the datasheet for reflow profile limits and tape and reel dimensions to ensure compatibility with assembly processes. Validate that the 3.3V supply requirement aligns with the system design.

Oscillators Selection Notes

Select this component when a differential VCXO with factory programmability is required to eliminate custom quartz lead times. It is suitable for designs needing immunity to mechanical stress and thermal variations. Consider the 6-SMD package size for space-constrained layouts. Ensure the application benefits from integrated power regulation features that simplify the bill of materials by removing external components.

Oscillators Part Context

This model belongs to the SiT3372 family of ultra-low jitter differential MEMS VCXOs. The series supports frequencies from 1 MHz to 220 MHz. The AI suffix indicates specific packaging and performance characteristics within the product line. The family is designed to replace traditional quartz oscillators in high-performance computing and telecom sectors.

Oscillators Replacement Considerations

Substitutes must match the 135 MHz frequency, LVPECL output, and 3.3V supply. Verify pinout compatibility for the 6-SMD package. Compare jitter specifications and pull range requirements against the original design constraints.
