Why Matterhorn™

Low active power. Low BOM. Low risk.

With no serial memory, low active power in USB4 and DP-ALT modes, and full USB4, USB 3.2 and DisplayPort compliance, there’s a lot less to worry about

Fully optimized USB4

Matterhorn allows every USB4 device to be the best it can be-optimizing data transfer and hitting the highest speeds the USB4 spec has to offer, whilst also future-proofing it for newer versions

Highly Maneuverable

Matterhorn’s 5x5 mm package is up to 50% smaller than competitors, giving you a lot more room to maneuver

Simple integration

Autonomous environment scoping and dynamic correction means there’s no system tuning required, whilst also enabling longer PCB traces. So once installed, it just works
