Overview

The LFTCXO085793 is a 38.88 MHz Temperature Compensated Crystal Oscillator (TCXO) designed for applications requiring high precision and stability. It provides an HCMOS output and operates from a 3.3V supply within a compact 5.0mm x 3.2mm 8-SMD package. This oscillator maintains tight frequency stability of +/-280ppb across a wide temperature range from -40C to 105C.

Why Choose This Part

This TCXO offers exceptional frequency stability of +/-280ppb, making it significantly more accurate than standard crystal oscillators. The extended operating temperature range up to 105C ensures reliable performance in demanding industrial or outdoor environments. Its 3.3V HCMOS output simplifies integration with modern digital logic and FPGAs.

Applications

Base Station Synchronization
Provides a stable reference clock for wireless infrastructure and telecommunications equipment requiring precise timing.
Precision Instrumentation
Acts as a reliable frequency source for measuring devices that operate in environments with significant temperature fluctuations.
SDH/SONET Networking
Ideal for synchronous digital hierarchy systems that need consistent 38.88 MHz clocking for data transmission.
Satellite Communications
Used in ground station equipment where high frequency stability is critical for signal integrity.

Getting Started

To use this oscillator, ensure a stable 3.3V supply is provided to the Vcc pin with a 0.1uF ceramic decoupling capacitor placed as close to the device as possible. The 8-SMD footprint requires standard reflow soldering processes; refer to the land pattern for optimal thermal and mechanical stability. Verify that the load capacitance on the HCMOS output does not exceed the maximum rating to maintain signal integrity.
