Buy inexpensive 25 MHz SMD oscillating crystals for Single Pair Ethernet (SPE) applications

Posted on by February 16, 2025

Since the early 1980s, the Ethernet standard has evolved from a simple communication method between computer networks to the most widely used protocol in industrial communication. Copper cables, whether 2-pair for Fast Ethernet or 4-pair for Gigabit Ethernet, form the backbone of many corporate and industrial networks. The introduction of Single Pair Ethernet (SPE) technology, inspired by developments in the automotive industry, is now opening up completely new fields of application.
