LFTVXO009909

Overview

The LFTVXO009909 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 supply voltage of 3.3 V and features amplitude control capabilities. It is housed in an 8-SMD module package, designed for surface mount installation. The unit maintains a frequency stability of 0.9 PPM and includes a load capacitance specification of 15 pF.

Feature Summary

• Integrated temperature compensation for stable frequency performance
• Voltage-controlled operation with amplitude adjustment capability
• HCMOS digital output interface

Applications

• Precision timing circuits requiring low drift
• Communication systems utilizing standard clock frequencies
• Industrial equipment needing reliable oscillator sources

Procurement Notes

Verify the specific operating voltage and output logic levels against your system requirements before integration. Confirm that the 8-SMD package dimensions align with your PCB footprint constraints. Ensure the supply voltage matches the specified 3.3 V to prevent damage or malfunction. Check for any recent product change notifications from the manufacturer regarding pinout or electrical characteristics updates.

Selection Notes

Select this component when a precise 32.768 MHz reference is required with high stability. Consider the 0.9 PPM stability rating for applications sensitive to frequency drift. Evaluate the 8-SMD form factor for space-constrained designs. Compare against other VCTCXOs if variable frequency tuning is needed beyond standard fixed-frequency operations.

Part Context

This oscillator belongs to the VCTCXO category within IQD's frequency product portfolio. It utilizes a quartz crystal as the basic resonator element. The series is designed for applications demanding superior frequency accuracy over varying environmental conditions compared to standard VCXOs.

Replacement Considerations

Cross-reference with other 32.768 MHz VCTCXOs offering similar 0.9 PPM stability and 3.3 V operation. Verify compatibility of the 8-SMD package and HCMOS output signal levels with existing circuit designs.
