SIT3372AC-1E9-25NY51.200000

Oscillators Overview

The SiTime SIT3372AC-1E9-25NY51.200000 is a MEMS Voltage Controlled Crystal Oscillator (VCXO) operating at 51.2 MHz with LVPECL output signaling. It functions within a 2.5V supply voltage range and features a frequency stability of ±35 ppm. The device supports an absolute pull range of ±3170 ppm, enabling precise frequency tuning. Designed for low-jitter applications, it utilizes DualMEMS temperature sensing and TurboCompensation technology to resist thermal gradients and vibration. The component is housed in a compact 6-SMD, No Lead Exposed Pad package, measuring 7.00mm x 5.00mm, suitable for surface mount installation.

Oscillators Feature Summary

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

Oscillators Applications

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

Oscillators Procurement Notes

Verify the complete part number including suffixes to ensure correct voltage, output type, and frequency specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check datasheet for reflow profile limits and tape/reel dimensions to align with pick-and-place equipment capabilities. Ensure design-in documentation matches the specific Elite Platform configuration requested.

Oscillators Selection Notes

Select this model when a 51.2 MHz VCXO with LVPECL outputs is required. The 2.5V supply and ±35 ppm stability define the electrical constraints. Consider the 6-SMD package size for board space limitations. Verify that the ±3170 ppm pull range meets system tuning requirements. Compare against other SiT3372 variants if different voltages or output formats like LVDS are needed.

Oscillators Part Context

This component belongs to the SiT3372 Elite Platform series from SiTime. The series offers ultra-low jitter differential VCXOs ranging from 1 MHz to 220 MHz. These devices replace traditional quartz oscillators using MEMS technology. The platform provides programmability to reduce lead times and customization costs associated with custom-built quartz frequencies.

Oscillators Replacement Considerations
