Overview

The ECS-3963-080-BN-TR is an 80 MHz fixed-frequency crystal oscillator (XO) designed for high-speed clocking applications. It operates from a 3.3V supply and provides a standard HCMOS output in a compact 5.0mm x 3.2mm surface-mount package. This component features an enable/disable function on pin 1, allowing for power savings in sensitive embedded designs.

Why Choose This Part

This oscillator offers a tight frequency stability of +/-50ppm across its entire operating temperature range, ensuring timing accuracy in harsh environments. The standard 5032 footprint and 1.3mm profile make it a drop-in solution for space-constrained PCB layouts needing low-jitter clocking.

Applications

Microcontroller System Clocking
Provides a high-stability 80 MHz external clock source for MCUs that require precise timing for high-speed peripherals.
Ethernet and Networking
Suitable for driving PHY chips or network processors requiring fixed-frequency reference signals.
Data Acquisition Systems
Acts as a reliable timing reference for high-speed ADCs and DACs to ensure consistent sampling intervals.
Embedded Computing
Used in industrial computing modules where a wide operating temperature range from -40C to +85C is required.

Getting Started

To use this device, provide a stable 3.3V supply to pin 4 and ground pin 2. Use a 0.01uF to 0.1uF ceramic decoupling capacitor placed as close as possible to the VDD pin to minimize supply noise. Note that pin 1 must be pulled high or left floating to enable the 80 MHz output, while pulling it low will place the device into a high-impedance standby mode.
