Selecting an Ethernet ICM the easy way

An ICM, or integrated connector module is a type of connector that integrates all the magnetics required to meet the Ethernet standard for xBASE-T connections. While it is possible to achieve this with simple standalone connectors and discrete magnetics, in practice this is only done in very high volume situations where fractions of a cent need to be saved.

ICMs provide a quick and easy, integrated solution which effectively guarantees the standards will be met, but it's not quite as simple as picking one and adding it to your design. In this week's Engineers' Insight Marco Enge looks through the standards, features and system requirements that may affect your connector selection.
