SIT3372AC-2E2-28NC148.350000

Oscillators Overview

The SiTime SIT3372AC-2E2-28NC148.350000 is a differential MEMS Voltage-Controlled Crystal Oscillator (VCXO) operating at 148.35 MHz. It features LVDS output signaling and functions within a supply voltage range of 2.52 V to 3.08 V, with a typical nominal voltage of 2.8 V. The device exhibits a frequency stability of 25 ppm and operates across an extended temperature range from -20°C to +70°C. Packaged in a compact 6-SMD, No Lead Exposed Pad form factor measuring approximately 3.2 mm by 2.5 mm, it integrates on-chip regulators to filter power supply noise.

Oscillators Feature Summary

• Utilizes DualMEMS temperature sensing and TurboCompensation technology for resistance to airflow, thermal gradients, shock, and vibration.
• Integrates 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 infrastructure requiring low-jitter clock signals
• Networking equipment demanding precise timing synchronization
• Industrial applications operating in noisy or dynamic environments

Oscillators Procurement Notes

Verify the complete part number against official SiTime documentation to ensure correct configuration of output format, voltage, and stability specifications. Confirm that the LVDS output type and 2.8V supply requirement align with the target system design. Check for RoHS compliance status and appropriate reflow profile requirements during assembly. Ensure availability through authorized distributors as stock levels may vary.

Oscillators Selection Notes

Select this component when a differential VCXO with low jitter and high immunity to environmental stressors is required. The integrated noise filtering simplifies PCB layout by removing the need for external linear regulators. Consider the 25 ppm stability and -20°C to +70°C operating range for industrial or telecom use cases where quartz alternatives might introduce longer lead times or customization costs.

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 and offers factory programmability to replace custom quartz oscillators. The AC suffix typically denotes specific stability and temperature performance grades within the product line, designed to optimize clock configurations while reducing development time.

Oscillators Replacement Considerations

Direct replacement requires matching the 148.35 MHz frequency, LVDS output, and 2.8V supply voltage. Verify that any substitute component supports the same 25 ppm stability and -20°C to +70°C operating range. Ensure the replacement package matches the 6-SMD No Lead Exposed Pad footprint and pinout compatibility for seamless integration.
