LFTVXO009917BULK

Overview

The LFTVXO009917BULK is a surface-mount voltage-controlled temperature-compensated crystal oscillator (VC-TCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 20 MHz with a stability of ±0.5 ppm and includes a 15 pF load capacitance. The device utilizes HCMOS output format with a maximum duty cycle of 55% and requires a 3.3 V supply voltage. Packaged in an 8-pin SMD configuration, it is designed for precision timing applications requiring high frequency stability across varying environmental conditions.

Feature Summary

• Integrates voltage control with temperature compensation for enhanced frequency accuracy
• Delivers high stability performance suitable for precision timing circuits
• Utilizes compact surface-mount packaging for automated assembly

Applications

• Precision communication systems requiring stable carrier frequencies
• Test and measurement equipment demanding low phase noise
• Industrial control systems operating in variable thermal environments

Procurement Notes

Verify the specific revision status and lead times directly with authorized distributors or IQD sales offices, as component availability may fluctuate. Confirm that the 3.3 V supply requirement aligns with your system design before procurement. Ensure compliance with RoHS directives if required for your region. Cross-reference the datasheet specifications against your application's thermal and electrical constraints to validate suitability.

Selection Notes

Select this component when a balance between voltage tunability and temperature stability is critical. The 20 MHz frequency suits standard digital clocking needs. Consider the 8-pin SMD footprint for board space constraints. Evaluate the ±0.5 ppm stability against your system's jitter tolerance requirements. Compare power consumption and output drive capabilities with alternative oscillators to ensure compatibility with downstream logic levels.

Part Context

This part belongs to IQD's VC-TCXO family, combining the benefits of voltage-controlled crystals with temperature compensation. It addresses the need for precise frequency generation in environments where ambient temperature fluctuations could otherwise degrade signal integrity. The series targets applications requiring higher reliability than standard TCXOs but without the complexity of OCXOs.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with any potential alternatives by matching frequency, stability, package dimensions, and supply voltage requirements.
