Overview

The LFTCXO085772 is a Temperature Compensated Crystal Oscillator (TCXO) from IQD Frequency Products operating at 19.2 MHz. It provides a stable HCMOS output from a 3.3V supply across an extended industrial temperature range of -40 to 105 degrees Celsius. This oscillator is designed for applications requiring tighter frequency stability than standard clock oscillators, featuring a 1ppm frequency tolerance.

Why Choose This Part

This TCXO offers superior frequency stability of 1ppm compared to standard quartz oscillators, making it suitable for precision timing. Its ability to operate reliably up to 105 degrees Celsius allows for deployment in harsh industrial environments where standard components might drift. The standard 7.0mm x 5.0mm footprint simplifies PCB integration for legacy system upgrades.

Applications

RF Transceivers
Provides a stable reference clock for wireless communication chipsets operating in the VHF/UHF bands.
Industrial Networking
Maintains timing synchronization in Ethernet switches and industrial gateways exposed to high-temperature environments.
GNSS Receivers
Serves as a reliable local oscillator for GPS/GNSS modules requiring high frequency stability for rapid signal acquisition.
Smart Metering
Ensures accurate long-term timing for utility meters located in outdoor enclosures with significant temperature fluctuations.

Getting Started

To integrate this component, ensure the 3.3V supply is decoupled with a 10nF to 100nF ceramic capacitor placed as close as possible to the VCC pin. The HCMOS output can directly drive standard CMOS logic levels; however, ensure the load capacitance does not exceed the specified maximum for the device to maintain signal integrity. Verification should be performed using a frequency counter or high-bandwidth oscilloscope with a low-capacitance probe.
