SIT3372AI-4E9-33NX140.000000

Oscillators Overview

The SIT3372AI-4E9-33NX140.000000 is a MEMS Voltage-Controlled Crystal Oscillator (VCXO) manufactured by SiTime, operating at a nominal frequency of 140 MHz. It features HCSL differential output signaling and requires a 3.3V supply voltage. The device utilizes a 6-SMD, No Lead package with an exposed pad, measuring 3.20mm x 2.50mm in size and 0.80mm in height. This component is engineered for low-jitter applications and incorporates DualMEMS temperature sensing and TurboCompensation technology to ensure stability against thermal gradients, shock, and vibration.

Oscillators Feature Summary

• Integrates DualMEMS temperature sensing and TurboCompensation technology for resistance to airflow, thermal gradients, shock, and vibration.
• Includes multiple on-chip regulators to filter power supply noise, eliminating the need for dedicated external LDOs.
• Factory programmable for specific combinations of frequency, stability, voltage, output signaling, and pull range.

Oscillators Applications

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

Oscillators Procurement Notes

Verify that the specific suffix '4E9' corresponds to the required HCSL output type and 3.3V supply voltage configuration. Confirm the 140 MHz frequency matches system requirements. Ensure the 6-SMD no-lead package footprint aligns with the PCB layout. Check for RoHS compliance and material declarations if required by project specifications.

Oscillators Selection Notes

Select this model when a differential HCSL output is required at 140 MHz with a 3.3V supply. Choose over standard oscillators if dynamic performance against vibration and thermal stress is critical. Consider factory programmability if custom pull ranges or stability levels are needed beyond standard quartz options.
