SIT3372AI-4B3-28NU184.320000

Oscillators Overview

The SiTime SIT3372AI-4B3-28NU184.320000 is a differential MEMS Voltage-Controlled Crystal Oscillator (VCXO) operating at a nominal frequency of 184.32 MHz. It utilizes HCSL output signaling and requires a 2.8V supply voltage. The device features a frequency stability of ±50 ppm and an Absolute Pull Range (APR) of ±3145 ppm. It is housed in a compact 6-SMD, No Lead package designed for surface mount applications.

Oscillators Feature Summary

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

Oscillators Applications

• Telecommunications systems requiring precise timing
• Networking equipment with low-jitter requirements
• Industrial applications operating in noisy environments

Oscillators Procurement Notes

Verify the complete part number including suffixes to ensure correct voltage, output type, and pull range specifications. Confirm that the 2.8V supply requirement aligns with the target system design. Check reflow profile compliance for the 6-SMD package during assembly. Ensure ESD protection measures are followed as per standard semiconductor handling guidelines.

Oscillators Selection Notes

Select this component when a differential VCXO with high pullability is required for jitter-sensitive applications. The integrated noise filtering simplifies board layout by removing external LDOs. Consider the ±3145 ppm pull range for frequency tuning needs. Verify that the HCSL output interface matches the receiving device inputs.

Oscillators Part Context

This model belongs to the SiT3372 Elite Platform series, which offers ultra-low jitter performance across a 1 MHz to 220 MHz range. The series replaces traditional quartz devices by offering programmability and shorter lead times. It is designed for reliability in harsh environments using MEMS technology.

Oscillators Replacement Considerations

Other SIT3372 variants with different output types or voltages may serve as functional substitutes if electrical parameters match. Cross-reference specific suffix codes for exact pin-out and signal compatibility before substitution.
