LFTCXO063781BULK

Overview

The LFTCXO063781BULK is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by IQD Frequency Products, operating at a nominal frequency of 10 MHz. It utilizes surface-mount technology in a compact 5.3mm x 3.2mm x 2.0mm package. The device provides high frequency stability with an initial tolerance of ±0.14 ppm and a maximum aging rate of ±1 ppm per year. It functions within an extended temperature range of -40°C to +85°C and requires a supply voltage of 3.3V.

Feature Summary

• High precision frequency stability with ±0.14 ppm initial tolerance
• Low aging rate ensuring long-term accuracy over time
• Extended industrial temperature operation capability
• Compact surface-mount design for space-constrained applications

Applications

• Precision timing circuits requiring low drift
• Industrial communication systems
• Test and measurement equipment
• Medical instrumentation

Procurement Notes

Verify the specific suffix and packaging configuration when ordering, as bulk packaging may differ from standard tape-and-reel formats. Confirm that the 3.3V supply requirement aligns with your system's power rails. Ensure the ±0.14 ppm stability meets your application's jitter and phase noise specifications. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when high short-term and long-term frequency stability is critical. The 10 MHz output is suitable for reference clocks in digital signal processing. Consider the 3.3V operating voltage and SMD footprint during PCB layout. Compare against lower-stability SPXOs if cost is a primary constraint, but retain this TCXO for applications demanding minimal temperature-induced drift.

Part Context

This part belongs to IQD Frequency Products' TCXO portfolio, designed for applications needing reliable clock sources beyond standard crystal oscillators. The manufacturer specializes in quartz-based frequency control solutions, offering various packages and frequencies. This specific model targets markets where size, stability, and temperature resilience are prioritized over ultra-low cost alternatives.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. When evaluating alternatives, ensure the replacement matches the 10 MHz frequency, 3.3V supply, 5.3x3.2mm footprint, and ±0.14 ppm stability. Verify that any cross-reference maintains the same aging rate and temperature range specifications.
