LFTVXO075809

Overview

The LFTVXO075809 is a Voltage-Controlled Temperature-Compensated Crystal Oscillator (VCTCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 32.768 MHz and utilizes a crystal as its basic resonator. The device provides a clipped sine wave output format and is designed for surface mount installation in a compact 4-SMD, No Lead package with dimensions of 3.20mm x 2.50mm and a maximum seated height of 1.00mm. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates voltage control and temperature compensation for high stability.
• Delivers clipped sine wave output suitable for RF applications.
• Utilizes a quartz crystal resonator for precise frequency generation.

Applications

• Wireless communication systems requiring stable reference clocks
• Portable electronic devices with space constraints
• Industrial instrumentation needing reliable timing signals

Procurement Notes

Verify the specific frequency tolerance and pull range requirements against the official datasheet before procurement. Confirm that the clipped sine wave output interface matches the receiving circuit's input impedance and voltage levels. Ensure the 4-SMD package footprint aligns with the PCB layout guidelines provided in the manufacturer's documentation to guarantee proper soldering and mechanical stability.

Selection Notes

Select this component when a low-profile oscillator is required for frequencies around 32.768 MHz. Consider the 4-SMD package size if board real estate is limited compared to larger 6-pin alternatives. Evaluate the need for voltage control tuning capabilities versus fixed-frequency TCXOs. Verify that the operating temperature range meets the environmental conditions of the target application.

Part Context

This part belongs to the LFTVXO series from IQD Frequency Products, which specializes in miniature oscillators. The series includes various models with different frequencies and package sizes, such as the 6-SMD variants like LFTVXO076345. These components are designed for applications demanding high stability in small form factors, often used in mobile and industrial electronics where space and performance are critical.

Replacement Considerations

Direct substitutes may include other IQD VCTCXOs in the same 4-SMD package family, such as LFTVXO075807 or LFTVXO075809 variants with different frequencies. Cross-manufacturer replacements require matching the 32.768 MHz frequency, clipped sine output, and 4-SMD footprint. Always verify electrical parameters and pinout compatibility before substitution.
