LFTVXO009909BULK

Overview

The LFTVXO009909BULK 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 ±500 ppb. It is housed in an 8-SMD module package with dimensions of 7.00mm x 5.00mm x 2.00mm. The operational temperature range spans from -40°C to +85°C, and the maximum supply current is specified as 3mA.

Feature Summary

• Integrates voltage-controlled tuning for precise frequency adjustment within VCTCXO architecture
• Employs temperature compensation circuitry to maintain high frequency stability across wide thermal ranges
• Delivers standard HCMOS logic output signals suitable for digital interface compatibility

Applications

• Precision timing references in telecommunications equipment
• Clock generation for embedded systems requiring stable low-frequency sources
• Industrial control applications operating in variable thermal environments

Procurement Notes

Verify the specific ordering suffix and packaging configuration against official IQD documentation before procurement. Confirm that the required frequency tolerance and voltage control characteristics align with system design specifications. Ensure compatibility with the 3.3V power supply rail and HCMOS input thresholds of downstream components. Check for any RoHS compliance requirements or environmental restrictions relevant to the target application market.

Selection Notes

Select this component when a stable 32.768 MHz reference is needed with voltage-tunable capabilities. Consider the 8-SMD footprint constraints and the -40°C to +85°C operating range for environmental suitability. Evaluate if the ±500 ppb stability meets the system's jitter and phase noise requirements compared to standard XO or TCXO alternatives.

Part Context

This part belongs to the LFTVXO series of surface-mount oscillators from IQD Frequency Products. It utilizes a crystal resonator as the basic frequency-determining element. The device is designed for applications demanding higher stability than standard crystals but with tuning flexibility provided by the voltage-control feature, distinguishing it from fixed-frequency TCXOs.

Replacement Considerations

Consult official IQD substitution guides for direct replacements. Verify pinout compatibility and electrical parameters such as supply voltage and output logic levels. Ensure the replacement maintains the same frequency, stability class, and physical package dimensions.
