Overview

The ECS-TXO-2520-33-240-AN-TR is a Temperature Compensated Crystal Oscillator (TCXO) that provides a stable 24 MHz clock source in a compact 2.50mm x 2.00mm package. Operating from a 3.3V supply, it features HCMOS output logic and an enable/disable function for power management. This component is designed for applications requiring tighter frequency stability than standard oscillators, maintaining +/-2.5ppm over its operating temperature range.

Why Choose This Part

The primary advantage of this TCXO is its high frequency stability of +/-2.5ppm across a wide temperature range of -40 to +85 degrees Celsius. Its small 2520 footprint and low 0.9mm profile make it suitable for high-density PCB layouts, while the integrated enable/disable pin allows designers to reduce current consumption in battery-powered devices.

Applications

Wireless Transceivers
Provides a stable reference clock for RF frequency synthesis in sub-GHz and 2.4GHz radios.
GNSS Receivers
Ensures accurate timing for satellite signal acquisition in GPS/GNSS positioning systems.
Industrial Networking
Serves as a reliable system clock for Ethernet PHYs and industrial communication gateways.
Precision Instrumentation
Acts as a timebase for portable measurement equipment requiring low frequency drift.

Getting Started

To integrate this oscillator, ensure a 0.01uF bypass capacitor is placed as close as possible to the VDD pin (Pin 4). The output (Pin 3) should drive a high-impedance HCMOS load; if driving a long PCB trace, consider a series termination resistor to minimize signal reflections. Use the enable/disable pin (Pin 1) to toggle the output, noting that the output enters a high-impedance state when disabled.
