XO5084-031R

Overview

The XO5084-031R is a 12.8 MHz Oven-Controlled Crystal Oscillator (OCXO) manufactured by MtronPTI. It operates at 3.3V and features an HCMOS output interface. The device measures 25.50mm x 25.50mm with a through-hole mounting type. It supports an operating temperature range of -40°C to +85°C and has a maximum supply current of 1.2A.

Feature Summary

• Provides oven-controlled stability for high-frequency precision applications
• Delivers low phase noise performance suitable for demanding signal integrity requirements
• Features robust mechanical construction designed for reliable operation in varied thermal environments

Applications

• Telecommunications base station synchronization
• High-performance test and measurement instrumentation
• Precision timing systems requiring stable reference frequencies

Procurement Notes

Verify the specific frequency tolerance and aging specifications against the official datasheet before procurement, as these parameters are critical for system timing accuracy. Confirm that the 3.3V HCMOS logic levels match the receiving circuit's input requirements. Ensure the through-hole package dimensions align with the designated PCB footprint and thermal management strategy.

Selection Notes

Select this component when superior frequency stability and low jitter are required compared to standard TCXOs or SCXOs. The OCXO technology ensures consistent performance across wide temperature variations. Consider the higher power consumption and larger form factor relative to smaller oscillators when evaluating board space and thermal design constraints.

Part Context

This part belongs to the XO5084 series of OCXOs from MtronPTI. The series includes variants such as the XO5084-044SR, offering different frequency tolerances like ±10 ppb or ±20 ppb. These oscillators are engineered for applications where long-term stability and minimal phase noise are paramount.

Replacement Considerations

Direct substitutes include other XO5084 variants with matching pinouts and voltages, such as the XO5084-044SR, provided the specific frequency tolerance meets the design requirements.
