Swiss startup Kandou has started volume production of its latest Matterhorn USB-C multiprotocol USB4 retimer chip.

The Matterhorn KB8010 extends the feature set of earlier Matterhorn retimers, adding support for DisplayPort 2.0 functionality to target mobile, tablet and desktop PC applications.

This addition of DisplayPort 2.0 functionality to KB8010 meets the increasing demand for increased bandwidth with 77.4Gbit/s, nearly triple the bandwidth of DisplayPort 1.4a at 25.92Gbit/s. This allows DP2.0 to handle 16K resolution with HDR at 60Hz, a 10K resolution with HDR at 80Hz or two displays with 8K resolution at 120Hz.

As well as support for DP2.0, KB8010 supports the optional USB4 low-power (CLx) states, USB3.2 Gen 2×2 (20Gbps), supports 1.8V IO logic and doubles the number of I2C device addresses, enabling system designers to reduce components on the motherboard and decrease system cost.

Kandou’s KB8010 USB4 retimer is sampling now and will ship in volume production starting Q1 2023. An evaluation kit and full product documentation are available to support customer evaluation and implementation in laptop, notebook, desktop and other host systems that support USB4 and DisplayPort.

“Kandou’s mission is to improve customer experiences with electronic devices by delivering cutting-edge chip-to-chip communications solutions,” said Amin Shokrollahi, Founder and CEO of Kandou. “Matterhorn’s market-leading features, compliance readiness and proven interoperability with hundreds of industry products are the key reasons why five of the top six PC OEMs have deployed Matterhorn in their personal computing platforms.”

Samples of KB8010 and evaluation kits are available now.
