KTM50x0 Family USB Type-C® Alt Mode to 3x DP1.4a or HDMI2.0b (DP++)/USB-A

Kinetic Technologies' KTM50x0 family is an advanced DisplayPort™ (DP) 1.4a MST hub with an integrated USB Type-C demultiplexer (demux), targeted ‎primarily for mobile notebook accessory and display applications. This device functions as a multi-stream audio-video splitter and ‎protocol converter with an HDCP1.x/ HDCP2.3 repeater supporting both Display Stream Compression (DSC) and uncompressed AV ‎streams.

The KTM50x0 has a DP Alt Mode capable USB Type-C upstream facing port (UFP). The four high-speed lanes of UFP can receive ‎DP1.4a multi-stream transport (MST) audio-video and USB3.2 Gen2 data streams simultaneously. The flexible input lane mapping ‎meets standard DP or USB Type-C connector with flip orientation requirements. The incoming DP and USB signals are demuxed, ‎retimed, and transmitted on the downstream facing ports (DFP). The KTM50x0 consists of three AC-coupled DP/DP++ or DC-coupled ‎HDMI/DVI DFPs, each with four high-speed lanes and one USB port with USB 3.2 TX and RX pair. The stream routing logic in ‎KTM50x0 allows flexible routing of incoming DP MST converted into any combination of MST or single-stream transport (SST) on ‎any video DFP with link rate and lane count change option. Also, the SST can be replicated on two or more DFPs. In addition, the DP ‎SST can be converted into an HDMI or DVI output transition minimized differential signaling (TMDS) format.

The combo receiver in KTM50x0 supports all DP standard data rates up to High Bit Rate 3 (HBR3) (8.1 Gbps/lane) and USB 3.2 Gen1 ‎‎(5.0 Gbps) and Gen2 (10.0 Gbps). The dual mode (DP++) transmitters support DP standard data rates up to 8.1 Gbps/lane and TMDS ‎data rates up to 6.0 Gbps/lane.
