Description

The KTM5030 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 multistream

audio-video splitter and protocol converter with

an HDCP1.x/ HDCP2.3 repeater supporting both

compressed (DSC) and uncompressed AV streams.

KTM5030 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 KTM5030

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 KTM5030 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 KTM5030 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.

KTM5030 is capable of processing up to six DP audiovideo

streams compressed or uncompressed. FEC

decoding and encoding is employed for the reliable

reception and transmission of DSC1.2a compressed

streams. These streams can be part of one single

large video timing or six independent video timings

from a single source with corresponding independent

multi-channel audio. The highest video timing per

stream and the number of streams transported is

limited by the DP1.4a and HDMI2.0 link bandwidth.

When the received DP MST stream is in DSC1.2a

compressed format, KTM5030 can decode the

streams (max two streams) or pass through to the

downstream sink or to another cascaded KTM5030

device. If a DP source sends an 8k4k60Hz

RGB/YCC444 DSC1.2a encoded video as four

4k2k60Hz MST, then two KTM5030 devices are

needed to decode all four streams. KTM5030 supports

both RGB 444 and YCC444/422/420 video pixel

encoding formats with a color depth up to 16 bpc (bits

per component or 48 bits per pixel). It has a pixel

processing unit capable of video pixel encoding format

conversion from RGB444 to YCC444 with bit depth

expansion and down scaling from YCC444 to

YCC422/420. Pixel format conversion along with

horizontal blanking expansion improves

interoperability and smooth rendering of CVT video

timings from a mobile PC on a consumer displays such

as TVs and projectors which supports only CEA

timings.

KTM5030 processes High Dynamic Range (HDR)

video content specified in BT601, BT709, BT2020,

BT2100 , Adobe RGB colorimetry format with the

proper metadata conversion from DP to HDMI. It also

offers secure reception and transmission of high

bandwidth digital audio and video content with

HDCP1.x or HDCP2.3 content protection. As a branch

device KTM5030 functions as a HDCP1.x and

HDCP2.3 repeater between the DP source and DP or

HDMI sink.

KTM5030 uses an external 25 MHz reference clock for

its operation. The reference clock can be generated

from a 25MHz crystal or from an external source. It has

a 300MHz ARM Cortex M3 CPU with on-chip

memories for code and data storage. The peripheral

subsystem includes SPI, UART (debug only), and I2C

master, slave interfaces. An internal Power-On Reset

(POR) circuit senses the voltage on the reset input and

provides the chip reset during system power-up. The

KTM5030 uses an external 16 Mbit SPI flash memory

for storing the RSA-2048 signed application firmware

with fail-safe recovery. At boot up, the CPU goes

through a secure boot process authenticating the

application code image stored in the SPI flash. It

supports both standard mode and quad mode SPI

operation. Firmware update for the SPI flash is done

securely through the DP AUX_CH or I2C host

interface (Secure In-System-Programming).
