Active30 in stock

Overview

The LFTCXO085791 is a 19.2 MHz Temperature Compensated Crystal Oscillator (TCXO) designed for high-stability timing applications. It provides an HCMOS output and operates from a 3.3V supply while maintaining a tight frequency stability of +/-280ppb. This component is particularly suited for systems requiring precision frequency references in demanding thermal environments up to 105 degrees Celsius.

Why Choose This Part

The LFTCXO085791 offers exceptional frequency stability of +/-280ppb across an extended temperature range of -40 to 105 degrees Celsius. Its compact 5.0mm x 3.2mm 8-SMD footprint and low 10mA maximum current consumption make it ideal for power-sensitive portable designs.

Applications

GNSS Receivers
Provides a stable reference clock for GPS and other satellite navigation systems to improve time-to-first-fix and tracking sensitivity.
Industrial IoT Gateways
Ensures reliable wireless communication and synchronization in harsh industrial environments with significant temperature fluctuations.
Digital Signal Processing
Acts as a low-jitter clock source for processors requiring precise 19.2 MHz timing for sampling and data conversion.
Smart Grid Infrastructure
Used in utility metering and grid monitoring equipment that demands long-term frequency stability and wide temperature range support.

Getting Started

When integrating this TCXO, ensure the 3.3V supply is properly decoupled with a 0.1uF ceramic capacitor placed as close to the Vcc pin as possible. The HCMOS output should be routed with a short, direct trace to the target IC to minimize signal degradation and electromagnetic interference. Standard SMT reflow profiles apply, but care should be taken to follow the manufacturer's specific soldering recommendations for 8-SMD packages to avoid thermal shock to the crystal.
