LFTCXO079058

Overview

The LFTCXO079058 is a temperature-compensated crystal oscillator (TCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 19.2 MHz and utilizes a clipped sine wave output format. The device is designed for surface-mount installation in a compact 4-SMD, No Lead package configuration. It functions within a supply voltage range centered around 1.8V. The component supports an extended industrial operating temperature range from -40°C to +85°C, ensuring stable performance under varying thermal conditions.

Feature Summary

• Integrates temperature compensation circuitry to maintain frequency stability across the specified operating temperature range.
• Delivers a clipped sine wave output signal suitable for interfacing with various digital logic families.
• Utilizes a low-profile surface-mount package design optimized for automated assembly processes.

Applications

• Wireless communication modules requiring precise clock synchronization
• Portable electronic devices with limited power budgets
• Industrial control systems operating in variable thermal environments

Procurement Notes

Verify the specific frequency tolerance and aging specifications against the official IQD datasheet prior to integration. Confirm that the 1.8V supply voltage aligns with the target system's power architecture. Ensure the clipped sine wave output compatibility matches the receiving circuit's input requirements. Check for any recent product change notifications or lifecycle status updates directly from the manufacturer.

Selection Notes
