SIT3373AI-4E2-25NH270.000000

Oscillators Overview

The SIT3373AI-4E2-25NH270.000000 is a MEMS-based Voltage-Controlled Crystal Oscillator (VCXO) manufactured by SiTime. It operates at a nominal frequency of 270 MHz and utilizes HCSL output signaling. The device is powered by a 2.5V supply voltage and features a frequency stability of 25 ppm. It is housed in a compact 6-SMD, No Lead package with an exposed pad, designed for surface-mount applications.

Oscillators Feature Summary

• Utilizes silicon MEMS technology for robust performance
• Provides differential HCSL output signaling
• Supports voltage-controlled frequency adjustment

Oscillators Applications

• High-speed data communication interfaces
• Clock generation for high-performance processors
• Telecommunications equipment requiring precise timing

Oscillators Procurement Notes

Verify the specific output type and supply voltage requirements against the system design before procurement. Confirm that the 6-SMD no-lead package footprint matches the PCB layout. Ensure the 25 ppm stability meets the application's jitter and phase noise specifications. Check for RoHS compliance status if required by regulatory standards.

Oscillators Selection Notes

Select this component when a low-jitter VCXO with HCSL outputs is required for 270 MHz applications. Consider the 2.5V supply constraint and the thermal characteristics of the exposed pad package. Evaluate the 25 ppm stability against system timing budgets. Compare alternative frequencies or output types if the exact 270 MHz specification does not align with the target design.

Oscillators Part Context

This part belongs to the SiT3373 series of ultra-low jitter VCXOs from SiTime. These oscillators are designed to replace traditional quartz crystals in demanding applications. The series offers programmability and reliability advantages over discrete crystal solutions. The specific model indicates a 270 MHz frequency with HCSL outputs and 2.5V operation.

Oscillators Replacement Considerations

Direct substitutes include other SiTime models within the SIT3373 family with compatible frequencies and output types. Verify pin compatibility and electrical parameters when considering cross-brand replacements. Ensure the replacement maintains the required HCSL signaling and 2.5V supply constraints.
