Overview

The ECS-TXO-5032-250-TR is a Temperature Compensated Crystal Oscillator (TCXO) providing a stable 25 MHz reference clock. Operating at 3.3V with an HCMOS output, it maintains a tight frequency stability of +/-2.5ppm across a wide temperature range of -30 to +85 degrees C. This 5.0mm x 3.2mm surface-mount component is designed for systems requiring higher precision than standard crystal oscillators.

Why Choose This Part

The +/-2.5ppm stability offers significant timing precision over standard oscillators, which typically range from 20ppm to 100ppm. Its integrated temperature compensation circuitry is housed in a compact 4-SMD package, saving board space while ensuring performance from -30 to +85 degrees C. The 3.3V HCMOS output ensures direct compatibility with most modern digital logic and microcontrollers.

Applications

Ethernet Controllers
Provides the 25 MHz reference clock required for physical layer (PHY) and MAC hardware to ensure stable data transmission.
Wireless Transceivers
Serves as a stable frequency source for RF synthesizer circuits where drift must be minimized across temperature changes.
Industrial Gateways
Ensures reliable communication timing in harsh environments with fluctuating ambient temperatures.
Embedded Systems Timing
Acts as a precision system clock for microcontrollers and FPGAs that require better than 50ppm stability.

Getting Started

When designing the PCB, place a 0.01uF to 0.1uF bypass capacitor as close to the VDD pin as possible to minimize noise. Ensure the trace from the output pin to the load is short to maintain signal integrity and avoid reflections. During prototyping, verify that the 15pF maximum load capacitance of the HCMOS output is not exceeded by the destination pin and trace parasitics.
