SIT3372AI-2B3-28NX100.000000

Oscillators Overview

The SiTime SIT3372AI-2B3-28NX100.000000 is a differential MEMS Voltage-Controlled Crystal Oscillator (VCXO) operating at a nominal frequency of 100 MHz. It utilizes DualMEMS temperature sensing and TurboCompensation technology for dynamic performance. The device features an LVDS output format and operates within a supply voltage range of 2.52 V to 3.08 V. It supports a pull range of 80 ppm with a frequency stability of 25 ppm. The component is housed in a 6-SMD, No Lead package measuring 3.2 mm x 2.5 mm x 0.85 mm and functions across a temperature range of -40 °C to +85 °C.

Oscillators Feature Summary

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

Oscillators Applications

• Telecommunications systems requiring precise clocking
• Networking equipment demanding low-jitter differential signals
• Industrial applications operating in noisy environments

Oscillators Procurement Notes

Verify the complete part number against official SiTime documentation to ensure correct configuration parameters. Confirm that the ordering suffix matches the required voltage, output type, and temperature grade. Check availability status as distribution may vary by region. Ensure compliance with RoHS standards if required by your manufacturing process.

Oscillators Selection Notes

Select this component when a differential VCXO with high dynamic stability is required. The integrated noise filtering simplifies board design by removing external LDO requirements. Consider the 80 ppm pull range for frequency adjustment needs. Verify that the LVDS output interface is compatible with the target receiver or FPGA inputs.

Oscillators Part Context

This model belongs to the SiT3372 family of ultra-low jitter differential MEMS VCXOs. The series covers frequencies from 1 MHz to 220 MHz. The AI suffix indicates an extended industrial temperature range. The 28NX suffix typically denotes the 2.8V supply and LVDS output configuration.

Oscillators Replacement Considerations

Direct replacements must match the 100 MHz frequency, LVDS output, and 3.2x2.5mm package. Other SiT3372 variants with different frequencies or output formats are not electrically compatible substitutes without circuit redesign.
