Overview

Automotive head units with remote displays typically have the infotainment features divided into multiple systems.  This makes the head unit more configurable by the OEM allowing for features to be added or removed for different vehicle models. Our integrated circuits and reference designs offer solutions that allow remote inter-connectivity of these while addressing reduced system external machine interface (EMI).
