SIT3372AI-2B3-25NU70.656000

Oscillators Overview

The SiTime SIT3372AI-2B3-25NU70.656000 is a differential MEMS Voltage-Controlled Crystal Oscillator (VCXO) operating at a nominal frequency of 70.656 MHz. It utilizes LVDS output signaling and requires a 2.5V supply voltage. The device features a ±50 ppm absolute frequency stability and an absolute pull range of ±3145 ppm. It is housed in a 6-SMD, No Lead package with dimensions of 7.00mm x 5.00mm and operates within a temperature range of -40°C to +85°C.

Oscillators Feature Summary

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

Oscillators Applications

• Telecommunications systems requiring variable frequency sources
• Networking equipment needing low-jitter clock signals
• Industrial applications operating in noisy environments

Oscillators Procurement Notes

Verify the complete part number against official SiTime documentation to ensure correct output type, voltage, and stability specifications. Confirm that the LVDS interface and 2.5V supply requirements match the target circuit design. Check for any specific manufacturing notes regarding reflow profiles or tape and reel dimensions required for assembly.

Oscillators Selection Notes

Select this component when a differential VCXO with wide pull range and high dynamic performance is required. The integrated noise filtering simplifies board layout by removing the need for external linear regulators. Ensure the application environment does not exceed the specified temperature range or mechanical stress limits defined in the datasheet.

Oscillators Part Context

This model belongs to the SiT3372 Elite Platform series, designed for ultra-low jitter differential MEMS VCXO applications. The series supports frequencies from 1 MHz to 220 MHz and offers factory programmability to replace custom quartz solutions, reducing lead times and customization costs while maintaining semiconductor-grade reliability.

Oscillators Replacement Considerations

Direct substitution requires matching the 70.656 MHz frequency, LVDS output, 2.5V supply, and 6-SMD package. Verify that alternative VCXOs provide comparable pull range and jitter performance if replacing with non-SiTime parts.
