LFTVXO063791BULK

Overview

The LFTVXO063791BULK 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 clipped sine wave output format. The device requires a single 3.3 V supply voltage and draws a maximum current of 10 mA. It features high frequency stability, typically specified within tight tolerances across its operating range. The component is housed in an 8-SMD surface-mount package with dimensions of approximately 5.0 mm x 3.2 mm x 2.0 mm. It supports control voltages up to 3 V for frequency adjustment and includes a load capacitance specification of 10 pF.

Feature Summary

• Integrated temperature compensation ensures stable frequency performance across varying thermal conditions.
• Voltage-controlled tuning capability allows for precise frequency adjustment via external control signals.
• Compact surface-mount design facilitates integration into space-constrained electronic circuits.

Applications

• Wireless communication systems requiring stable clock sources
• Industrial control equipment needing reliable timing references
• Automotive electronics applications demanding robust oscillator performance

Procurement Notes

Verify the specific frequency stability tolerance and control voltage range against the official datasheet before procurement, as these parameters can vary based on the exact sub-model or manufacturing batch. Confirm that the 8-SMD footprint matches your PCB layout requirements. Ensure the 3.3 V supply rail meets the current sourcing capabilities required by the 10 mA maximum draw. Check for any RoHS compliance documentation if environmental regulations apply to your project.

Selection Notes

Select this component when a compact, voltage-tunable oscillator with integrated temperature compensation is required for 19.2 MHz applications. It is suitable for designs where space is limited due to its small 5.0 mm x 3.2 mm package. Consider the clipped sine wave output compatibility with downstream logic or amplifiers. Evaluate the need for voltage control versus fixed-frequency alternatives to determine if the added complexity of the control pin is justified for your system's jitter or calibration requirements.
