Description

The MCDP5240 is an advanced USB Type-C /

DisplayPort1.4a to DP++ converter with an integrated

USB type-C de-multiplexer, targeted primarily for

Mobile Notebook accessory and display applications.

This device functions as a DP to DP re-timer with lane

count, link rate conversion option and DP to HDMI

protocol converter with an HDCP1.x/ HDCP2.x

repeater function.

The MCDP5240 has a DP alt-mode capable USB

Type-C Upstream Facing Port (UFP). The four high

speed lanes of UFP can receive DP1.4a audio-video

and USB3.1 Gen2 data streams simultaneously. The

input lane mapping is flexible and meets the USB

Type-C connector flip orientation requirements. The

incoming DP and USB signals are de-multiplexed,

retimed, and transmitted on the Downstream Facing

Ports (DFP). The MCDP5240 consists of a USB DFP

port with USB3.1 TX and RX pair and an audio-video

DFP port configured as AC coupled HDMI/DVI port,

each with four high-speed lanes.

The combo receiver in MCDP5240 supports all DP

standard data rates up to HBR3 (8.1Gbps/lane) and

USB3.1 Gen1 (5.0Gbps) and Gen2 (10.0Gbps). The

transmitter supports TMDS data format up to

6.0Gbps/lane. The side-band channel uses 1.0 Mbps

Manchester-coded AUX signaling for DP and DDC

signaling up to 100 kbps for the HDMI interface.

In the protocol converter mode, MCDP5240 translates

a DP SST stream into AC coupled HDMI2.0b output.

The highest video timing supported in this mode is

4k2k60Hz RGB/YCC 444 or 4k2k120Hz in YCC 420-

pixel format. It 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). The MCDP5240 also has a pixel processing

unit capable of video color space conversion from

RGB444 to YCC444 with bit depth expansion and pixel

encoding format conversion from YCC444 to

YCC422/420. It also supports advanced dithering

function to truncate the pixel bit depth to the precision

of the connected sink device. Pixel format conversion

along with horizontal blanking expansion improves

interoperability and smooth rendering of video from

mobile PC and tablets on legacy TVs. Besides,

MCDP5240 also supports HDMI CEC tunneling over

DP AUX channel for remote control pass-through, one

touch control of the connected devices in a CE system.

The MCDP5240 processes High Dynamic Range

(HDR) video content specified in BT601, BT709,

BT2020 or in the Adobe RGB colorimetry format with

the appropriate metadata conversion from DP to HDMI

standard. It also offers secure reception and

transmission of high bandwidth digital audio and video

content with HDCP1.x or HDCP2.x content protection.

MCDP5240 functions as an HDCP1.x and HDCP2.x

repeater between the DP source and DP or HDMI sink.

The MCDP52x0 can pass through DP SST or MST

uncompressed streams with the flexibility of lane count

and link rate conversion. The highest video timing per

stream and the number of streams transported is

limited by the DP1.4a link bandwidth.

The MCDP5240 uses an external crystal of 25MHz as

a reference clock for its operation. It has a 300MHz

ARM Cortex M3 CPU with on-chip memories for

storing data and code execution. The peripheral

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

master and slave interfaces. An internal Power-On

Reset (POR) circuit senses the voltage on the reset

input and provides the chip reset during system powerup.

The MCDP5240 uses an external 16Mbit 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

operation. A firmware update of the SPI flash is done

securely through the DP AUX_CH or I2C host

interface (Secure In-System-Programming).

Applications Information

The target applications of MCDP5240 are the notebook, tablet accessories i.e., adapters (dongles), docking stations

and other AV accessories. It is also intended for enabling USB Type-C DP alternative mode for inside-the-box

applications such as TVs, signage game consoles and other consumer equipment.

Adapter Application

In a dongle topology the MCDP5240 is part of the source side adaptor that plugs into a DP source device via a USB

Type-C connector at the upstream facing port. In a typical DP-to-HDMI dongle application, MCDP5240 functions as

a system master and operates as a protocol converter. In a USB type-C to HDMI dongle it can also function as a

Type-C Port Manager (TCPM) along with an external TCPC device (e.g. Kinetic MCDP9000 TCPC). The upstream

source typically powers the dongle. In DP to DP conversion mode, it converts the lane count and link rate to AC

coupled DisplayPort1.4 interface with HDCP1.x and 2.x repeater
