SIT3372AI-1E3-25NZ80.000000

Oscillators Overview

The SIT3372AI-1E3-25NZ80.000000 is a differential MEMS Voltage-Controlled Crystal Oscillator (VCXO) from SiTime’s Elite Platform, operating at a nominal frequency of 80 MHz. It utilizes DualMEMS temperature sensing and TurboCompensation technology to deliver low-jitter performance with resistance to thermal gradients, shock, and vibration. The device features LVPECL output signaling and operates on a 2.5V supply voltage. It provides a frequency stability of ±50 ppm and an absolute pull range of ±145 ppm. The component functions within a temperature range of -40°C to +85°C and is housed in a compact 7.00mm x 5.00mm surface-mount package.

Oscillators Feature Summary

• Industrial applications with noisy environments

Oscillators Procurement Notes

Verify the complete part number against official SiTime documentation to ensure correct configuration. Confirm that the ordering suffix matches the required output type, voltage, and pull range specifications for the design. Check current availability status as lead times may vary. Ensure compatibility with reflow profiles specified in manufacturing notes.

Oscillators Selection Notes

Select this component when low jitter and high reliability are critical in space-constrained designs. The MEMS architecture offers advantages over quartz by eliminating custom build times. Consider the 80 MHz frequency and LVPECL output for high-speed digital interfaces. Evaluate the ±145 ppm pull range against system tuning requirements.

Oscillators Part Context

This model belongs to the SiT3372 series, which covers a frequency range of 1 MHz to 220 MHz. The Elite Platform designation indicates advanced compensation technologies. The 'AI' suffix typically denotes specific automotive or industrial grade variants, while 'E3' often relates to lead-free compliance. The '25' indicates the 2.5V supply voltage.

Oscillators Replacement Considerations

Direct replacements must match the 80 MHz frequency, LVPECL output, and 2.5V supply. Verify pinout compatibility for the 6-SMD no-lead package. Cross-reference with other SiT3372 variants if different pull ranges or stabilities are acceptable.
