SIT3372AC-1E3-28NH30.720000

Oscillators Overview

The SiTime SIT3372AC-1E3-28NH30.720000 is a MEMS VCXO operating at 30.72 MHz with ±25 ppm stability and LVPECL output. It utilizes a 2.8V supply within a 6-SMD, no lead exposed pad package (7x5 mm). The device features DualMEMS temperature sensing and TurboCompensation technology for dynamic performance against shock, vibration, and thermal gradients. Integrated on-chip regulators filter power supply noise, eliminating the need for external LDOs. Factory programmability allows optimization of frequency, stability, voltage, and pull range.

Oscillators Feature Summary

• DualMEMS temperature sensing and TurboCompensation technology provide resistance to airflow, thermal gradients, shock, and vibration.
• Integrated on-chip regulators filter power supply noise, removing the requirement for dedicated external low-dropout regulators.
• Factory programmability enables customization of frequency, stability, voltage, output signaling, and pull range.

Oscillators Applications

• Telecommunications systems requiring precise clocking
• Networking equipment demanding low-jitter differential signals
• Industrial applications operating in noisy environments

Oscillators Procurement Notes

Verify the specific suffix codes against official SiTime documentation to confirm exact electrical parameters, including supply voltage tolerance, output format, and absolute pull range. Ensure the selected variant matches the required operating temperature range and package dimensions for the target PCB layout. Cross-reference the part number with manufacturer datasheets to validate factory programming options and compliance with RoHS standards before procurement.

Oscillators Selection Notes
