SIT3372AI-4B9-30NB184.320000

Oscillators Overview

The SiTime SIT3372AI-4B9-30NB184.320000 is a High-Clock-Speed-Limit (HCSL) output Voltage-Controlled Crystal Oscillator (VCXO) operating at a nominal frequency of 184.32 MHz. It utilizes MEMS technology with DualMEMS temperature sensing and TurboCompensation for dynamic stability. The device features integrated on-chip regulators to filter power supply noise, eliminating the need for external LDOs. It operates within a -40°C to +85°C industrial temperature range and supports a pull range up to 10 MHz. The component is housed in a compact 6-SMD, No Lead package.

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 programmable configuration allows optimization of frequency, stability, voltage, output signaling, and pull range.

Oscillators Applications

• Telecommunications equipment requiring precise timing synchronization
• Networking infrastructure components demanding low-jitter performance
• Industrial applications operating in noisy or thermally variable environments

Oscillators Procurement Notes

Verify that the specific ordering suffix matches the required HCSL output signaling and 184.32 MHz frequency. Confirm the 6-SMD package dimensions align with PCB layout constraints. Ensure the -40°C to +85°C temperature rating satisfies the operational environment requirements. Cross-reference the pull range specification against system tuning needs.

Oscillators Selection Notes

Select this VCXO when low jitter and high dynamic stability are critical in electrically noisy environments. The integrated noise filtering simplifies board design by reducing component count. Consider this part for applications requiring factory-programmable flexibility to avoid custom quartz lead times. Verify that the HCSL interface compatibility matches the receiving clock input specifications.
