LFOCXO063801BULK

Overview

The LFOCXO063801BULK is a high-performance oven-controlled crystal oscillator (OCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 12.8 MHz with an exceptional initial frequency tolerance of ±20 ppb over the operating temperature range. The device utilizes HCMOS output format and requires a single 3.3 V supply voltage. It features a compact surface-mount package measuring 14.4 mm in length, designed for space-constrained applications requiring superior stability.

Feature Summary

• Provides ultra-high frequency stability with ±20 ppb tolerance across the full operating temperature range.
• Integrates an internal oven control mechanism to maintain consistent performance under varying environmental conditions.
• Delivers digital clock signals via a standard HCMOS output interface compatible with common logic families.

Applications

• Precision timing systems in telecommunications infrastructure
• High-accuracy test and measurement equipment
• Navigation and positioning systems requiring stable reference clocks

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific bulk packaging variant matches project requirements. Ensure supply chain compliance with RoHS directives. Validate electrical parameters against latest official datasheets prior to integration. Check for end-of-life status as indicated by current market availability.

Selection Notes

Select this OCXO when extreme frequency stability is critical and space allows for its physical dimensions. Consider the 3.3 V supply constraint and HCMOS drive capability. Evaluate thermal management needs due to oven operation. Compare aging rates and warm-up times against system startup requirements. Ensure compatibility with existing PCB layout constraints for the specified SMD footprint.

Part Context

This component belongs to IQD's LFOCXO series of oven-controlled oscillators, designed for applications demanding superior frequency accuracy compared to standard TCXOs or XOs. The series typically offers low phase noise and minimal drift over time and temperature variations, serving as a primary reference source in sensitive electronic systems.
