KTM5000 / RD4-5000
USB Type-C / DisplayPort1.4 MST Hub

General Description

The KTM50x0 is an advanced DisplayPort1.4a MST hub with an integrated USB type-C de-multiplexer, targeted primarily for Mobile Notebook accessory and display applications. This device functions as a multi-stream audiovideo splitter and protocol converter
with an HDCP1.x/ HDCP2.3 repeater supporting both compressed (DSC) and uncompressed AV streams.
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 MST audio-video and USB3.2 Gen2 data streams simultaneously. The input lane mapping is flexible and meets standard DP or the USB Type-C connector with flip orientation requirements. The incoming DP and USB signals are de-multiplexed, 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 USB3.2 TX and RX pair. The Stream Routing Logic in KTM50x0 allows flexible routing of incoming DP MST stream converted into any combination of MST or SST streams on any of the DFP video ports with link rate and lane count change option. Also, the SST stream can be replicated on two or more DFP ports. In addition, the DP SST stream can be converted into a HDMI or DVI output (TMDS signal format).
The combo receiver in KTM50x0 supports all DP standard data rates up to HBR3 (8.1 Gbps/lane) and USB3.2 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. The side-band channel uses 1.0 Mbps Manchester-coded AUX signaling for DP and DDC signaling up to 100kbps for the HDMI interface

Ordering Information

Detailed functionality of the IC is described in the KTM50x0 datasheet. Included in the kit are the following items:

EVAL Kit Photo

1. DFP Type A: USB 3.2 GEN2 and USB 2.0

2. DFP Type A: USB 3.2 GEN2 and USB 2.0

3. UFP Type C: Up to 60 Watts and DP1.4 and USB 3.2 GEN2 /USB 2.0

4. DFP TX1: DP++ (DP1.4b or HDMI 2.0b)

5. DFP TX2: HDMI2.0b

6. DFP TX3 Type C: USB GEN2 and DP Alt Mode

7. DFP Type C Charger: 100 Watts Preferred. Minimum 35 watt required to

support all DFPs. (5 V Charger is not enough)
UART: Debug and FW update

Connection Setup

1. DFP Type C Charger is required to turn on RD4.
2. UFP Type can’t power up RD4 board because RD4 is designed as the dock station.
3. DPF Type C(TX3): Max 7.5 watt

Recommended Sequence: Not mandatory but in general

• Connect 100-Watt Type C Charger (> 35Watt) to DPF Type C Charger
• Connect DPF TX1 or TX2 or TX3 or both or all
• Connect UFP Type C
