SIT3372AI-2B9-25NC135.000000

Oscillators Overview

The SIT3372AI-2B9-25NC135.000000 is a MEMS Voltage-Controlled Crystal Oscillator (VCXO) from SiTime's Elite Platform, operating at a nominal frequency of 135 MHz. It features an LVDS output interface and requires a 2.5V supply voltage. The device utilizes DualMEMS technology for temperature sensing and offers a frequency stability of ±35 ppm with an absolute pull range of ±60 ppm. It is housed in a compact 6-SMD, No Lead package with dimensions of 7.00mm x 5.00mm.

Oscillators Feature Summary

• DualMEMS temperature sensing technology ensures high stability across operating conditions
• LVDS differential output interface designed for low-jitter signal transmission
• Voltage-controlled operation allows precise frequency tuning within the specified pull range

Oscillators Applications

• High-speed serial communication links requiring precise clock synchronization
• Data acquisition systems needing stable reference frequencies
• Test and measurement equipment utilizing VCXO-based timing solutions

Oscillators Procurement Notes

Verify the specific ordering suffix to confirm the supply voltage and output type, as variations exist within the SIT3372 family. Ensure the design supports LVDS input requirements for downstream components. Confirm that the 6-SMD no-lead package footprint matches the PCB layout specifications. Check for any specific reflow soldering profile recommendations provided by the manufacturer for this surface-mount device.

Oscillators Selection Notes

Select this component when a differential LVDS output is required for noise immunity in high-frequency applications. The 2.5V supply option is suitable for lower voltage logic interfaces compared to 3.3V variants. Consider the ±35 ppm stability and ±60 ppm pull range against system jitter and tuning requirements. Evaluate the 135 MHz frequency against available alternatives if different standard frequencies are needed.

Oscillators Part Context

This part belongs to the SiT3372 series, which represents SiTime's Elite Platform MEMS oscillators. These devices are engineered to replace traditional quartz crystals and oscillators, offering superior shock resistance and programmability. The AI suffix typically denotes specific performance characteristics within the Elite Platform lineup, focusing on low phase noise and high reliability.

Oscillators Replacement Considerations

Direct pin-to-pin replacements may include other SIT3372 variants with different supply voltages or frequencies, such as SIT3372AI-2E9-33NC135.000000 for 3.3V operation. Verify electrical compatibility before substitution. Generic MEMS VCXOs from other manufacturers may not offer identical DualMEMS performance or LVDS drive strength.
