Overview

The LFTCXO085792 is a high-precision 20 MHz temperature-compensated crystal oscillator (TCXO) designed for stable frequency generation in demanding environments. It operates at 3.3V with an HCMOS output and maintains a very tight frequency stability of +/-280ppb across a wide temperature range of -40C to 105C.

Why Choose This Part

This TCXO offers exceptional frequency stability of +/-280ppb, making it significantly more accurate than standard oscillators. Its extended temperature range support up to 105C allows for deployment in harsh industrial applications without sacrificing timing integrity.

Applications

Precision Timing Reference
Serves as a stable clock source for industrial communication protocols that require minimal frequency drift.
Basestation Synchronization
Provides the necessary stability for small cell and wireless infrastructure timing synchronization.
Global Navigation Satellite Systems
Enhances GNSS receiver performance by providing a stable reference clock for faster signal acquisition.
IoT Edge Gateways
Ensures reliable long-term operation in outdoor or unconditioned environments where temperature fluctuations are common.
