SIT3373AC-4E2-25NZ345.600000

Oscillators Overview

The SIT3373AC-4E2-25NZ345.600000 is a MEMS-based Voltage-Controlled Crystal Oscillator (VCXO) manufactured by SiTime. It operates at a nominal frequency of 345.6 MHz with a supply voltage range of 2.5V to 3.63V, typically powered at 2.5V. The device features an HCSL output format and is housed in a compact 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a maximum height of 1.00mm. It supports an operating temperature range from -40°C to +85°C and offers a frequency stability of ±25 ppm.

Oscillators Feature Summary

• Utilizes silicon MEMS technology for enhanced reliability compared to traditional quartz resonators.
• Provides differential HCSL output signals suitable for high-speed digital interfaces.
• Offers precise voltage control for frequency tuning applications within the VCXO specification.

Oscillators Applications

• High-speed serial communication links requiring stable clock sources.
• Data acquisition systems needing precise timing synchronization.

Oscillators Procurement Notes

Verify the specific suffix codes against the official SiTime datasheet to ensure compatibility with required voltage levels, output formats, and tolerance specifications. Confirm that the exposed pad package requires appropriate thermal management and soldering techniques during assembly. Cross-reference the part number with current manufacturer availability as supply chain conditions may vary.

Oscillators Selection Notes

Select this component when a differential HCSL output is required alongside MEMS-based frequency stability. Ensure the design accommodates the 7x5mm footprint and the specific 2.5V or 3.3V power rail constraints. Validate that the ±25 ppm stability meets the system's jitter and phase noise requirements for the target application environment.

Oscillators Part Context

This model belongs to the SiTime Elite Platform family of MEMS oscillators. It shares the core MEMS resonator architecture with other SIT3373 variants but is distinguished by its specific frequency, output type, and packaging configuration. The platform is designed to replace traditional quartz crystals and oscillators in demanding electronic designs.

Oscillators Replacement Considerations

Direct replacements include other SIT3373 series parts with matching 345.6 MHz frequency and HCSL output, such as SIT3373AC-1B9-25NZ345.600000 or SIT3373AI-4E9-33NU345.600000Y, provided voltage and stability tolerances align with the original design requirements.
