SIT3372AI-2B3-25NU50.000000

Oscillators Overview

The SiTime SIT3372AI-2B3-25NU50.000000 is a MEMS Voltage-Controlled Crystal Oscillator (VCXO) operating at a nominal frequency of 50 MHz. It utilizes LVDS output signaling and functions with a 2.5V supply voltage. The device features a ±50 ppm absolute pull range and ±50 ppm frequency stability. It is housed in a compact 6-SMD, No Lead package measuring 7.00mm x 5.00mm with a maximum height of 1.00mm. Designed for low-jitter applications, it incorporates DualMEMS temperature sensing and TurboCompensation technology to resist environmental stressors.

Oscillators Procurement Notes

Verify the complete part number including suffixes against official SiTime documentation to ensure correct configuration. Confirm that the specified output format, voltage, and frequency match the design requirements. Check manufacturing notes for proper reflow profiles and tape and reel dimensions prior to assembly. Ensure compatibility with the target system's clock distribution network.

Oscillators Selection Notes

Select this component when a differential VCXO with precise frequency control and high environmental robustness is required. The integrated noise filtering simplifies board layout by removing the need for dedicated external linear regulators. Consider the programmability options if standard quartz alternatives present long lead times or customization constraints.

Oscillators Part Context

This model belongs to the SiT3372 Elite Platform series from SiTime. The series covers a frequency range of 1 MHz to 220 MHz and is engineered specifically for low-jitter timing applications. It represents a MEMS-based alternative to traditional quartz oscillators, offering superior dynamic performance and configurability.

Oscillators Replacement Considerations

Direct substitutes include other SIT3372 variants with different frequencies or output formats, such as SIT3372AI-2B3-25NU148.350000. Cross-model replacement requires verifying pinout compatibility and electrical parameter alignment.
