LFTVXO082847BULK

Overview

The LFTVXO082847BULK is a Voltage-Controlled Temperature-Compensated Crystal Oscillator (VCTCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 19.2 MHz with a high frequency stability of 0.14 ppm. The device utilizes HCMOS output format and requires a supply voltage range of 3.135 V to 3.465 V. Designed for surface-mount applications, it features a load capacitance of 15 pF and is housed in an 8-SMD, no-lead package.

Feature Summary

• Integrates temperature compensation for enhanced frequency stability
• Provides voltage-controlled tuning capability via external input
• Delivers digital HCMOS logic output signals
• Utilizes lead-free surface-mount packaging for automated assembly

Applications

• Precision timing circuits requiring low phase noise
• Telecommunications base station synchronization
• Test and measurement equipment clock sources
• High-performance computing system clocks

Procurement Notes

Verify the specific ordering suffix and package variant against the official IQD datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and check for any recent Product Change Notifications (PCNs) that may affect mechanical dimensions or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a stable 19.2 MHz reference is required with tight ppm tolerance. Ensure the application supports the 3.3V nominal supply and HCMOS interface. Evaluate thermal management needs as the oscillator includes internal compensation circuitry sensitive to ambient temperature variations within its specified operating range.

Part Context

This part belongs to the LFTVXO series of VCTCXOs from IQD Frequency Products. These oscillators are designed for applications demanding superior frequency stability compared to standard VCXOs. The series typically offers low aging rates and robust performance across industrial temperature ranges, serving as critical timing references in complex electronic systems.

Replacement Considerations

Direct substitutes include other 19.2 MHz VCTCXOs with 0.14 ppm stability and 8-SMD packages. Verify pinout compatibility and supply voltage ranges. Cross-reference with IQD's current portfolio for updated part numbers if the original is discontinued.
