Active22 in stock

Overview

The ECS-TXO-2520-33-400-AN-TR is a compact 40 MHz temperature-compensated crystal oscillator (TCXO) designed for applications requiring high frequency stability in a small footprint. It operates from a 3.3V supply and utilizes an HCMOS output, making it compatible with a wide range of modern microcontrollers and digital logic. The device features an enable/disable function and is housed in a miniature 2.5mm x 2.0mm 4-pin SMD package.

Why Choose This Part

This TCXO offers excellent frequency stability of +/-2.5ppm across a wide temperature range of -40 to +85 degrees Celsius. Its 2520-sized SMD package saves significant board space compared to traditional 3225 or 5032 oscillators while maintaining low current consumption of approximately 7mA.

Applications

Wireless Communication Modules
Provides a stable reference clock for RF transceivers where frequency drift must be minimized across temperature changes.
GPS/GNSS Receivers
Ensures precise timing for satellite signal acquisition and tracking in navigation systems.
IoT Edge Gateways
Serves as a reliable system clock for industrial gateways operating in environments with fluctuating ambient temperatures.
Precision Instrumentation
Acts as a low-jitter timing source for data acquisition systems and measurement equipment.

Getting Started

To implement this oscillator, ensure a 0.01uF to 0.1uF bypass capacitor is placed as close as possible to the 3.3V supply pin. Use the enable/disable pin (Pin 1) to reduce power consumption during system standby modes. Proper PCB layout techniques, including a solid ground plane and short traces, should be used to minimize electromagnetic interference and maintain signal integrity at 40 MHz.
