LFTVXO009919

Overview

The LFTVXO009919 is a Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 32.768 MHz with an HCMOS output format. The device requires a 3.3V supply voltage and features a frequency stability of ±500ppb. It is housed in an 8-SMD module package, designed for surface mount installation. The operational temperature range extends from -40°C to +85°C, ensuring reliability across industrial environments.

Feature Summary

• Integrates voltage control functionality with temperature compensation for enhanced frequency precision.
• Delivers a standard HCMOS digital output signal suitable for logic interfacing.
• Utilizes amplitude control mechanisms to maintain consistent signal integrity.

Applications

• Precision timing circuits requiring low drift
• Industrial communication systems
• Medical instrumentation

Procurement Notes

Verify the specific ordering suffix and package variant against the official IQD datasheet to ensure compatibility with design requirements. Confirm that the 8-SMD module footprint matches the PCB layout. Validate supply voltage and output logic levels before integration. Check for any recent product change notifications or lifecycle status updates directly from the manufacturer.

Selection Notes

Select this component when a stable 32.768 MHz reference is needed with voltage tuning capabilities. Consider the 8-SMD module size for space-constrained designs. Ensure the system can accommodate the 3.3V supply requirement. Evaluate thermal management needs given the wide operating temperature range. Compare stability specifications against application drift tolerances.
