SIT3372AI-4E2-25NZ70.656000

Oscillators Overview

The SiTime SIT3372AI-4E2-25NZ70.656000 is a differential MEMS Voltage-Controlled Crystal Oscillator (VCXO) operating at 70.656 MHz. It features HCSL output signaling and functions within a supply voltage range of 2.25 V to 2.5 V. The device provides a frequency stability of ±25 ppm across an industrial temperature range of -40°C to +85°C. Packaged in a compact 7 mm x 5 mm surface-mount format, it utilizes DualMEMS temperature sensing and TurboCompensation technology for enhanced dynamic performance.

Oscillators Feature Summary

• Integrates DualMEMS temperature sensing and TurboCompensation technology for resistance to thermal gradients, shock, and vibration.
• Includes on-chip regulators to filter power supply noise, eliminating the need for external LDOs.
• Factory programmable for specific combinations of frequency, stability, voltage, output signaling, and pull range.

Oscillators Applications

• Telecommunications equipment requiring precise clock synchronization
• Networking infrastructure components
• Industrial applications operating in noisy environments

Oscillators Procurement Notes

Verify that the ordering suffix matches the required output signaling type, as variations exist between HCSL and LVDS configurations for this family. Confirm the supply voltage requirement aligns with system design constraints, noting differences between 2.5V and 3.3V variants. Ensure the temperature grade corresponds to the operational environment specifications. Cross-reference the package dimensions against PCB footprint requirements before finalizing procurement orders.

Oscillators Selection Notes

Select this component when low jitter and high stability are critical for differential clock distribution. The factory programmability allows optimization of clock configurations without custom quartz manufacturing delays. Consider the integrated noise filtering capabilities for systems sensitive to power supply fluctuations. Evaluate the mechanical robustness against vibration and shock if deployed in mobile or harsh industrial settings compared to standard quartz alternatives.

Oscillators Part Context

This part belongs to the SiT3372 series of ultra-low jitter differential MEMS VCXOs. The series covers a frequency range from 1 MHz to 220 MHz. It is designed to replace traditional quartz oscillators in applications demanding superior dynamic performance and reliability under extreme environmental conditions.

Oscillators Replacement Considerations

Direct substitutes include other SiT3372 variants with matching frequency and output types, such as SIT3372AI-2B9-33NC70.656000 for LVDS output at 3.3V. Verify pin compatibility and electrical parameters before substitution.
