Description

The MCDP5290 is an advanced DisplayPort1.4a to

DP++ dual mode converter 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 receiver in MCDP5290 supports all DP standard

data rates up to HBR3 (8.1Gbps/lane). The dual mode

(DP++) transmitter support DP standard data formats

up to 8.1Gbps/lane or 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, MCDP5290 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 MCDP5290 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,

MCDP52x0 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 MCDP5290 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.

MCDP5290 functions as an HDCP1.x and HDCP2.x

repeater between the DP source and DP or HDMI sink.

The MCDP5290 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 MCDP5290 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 MCDP5290 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 MCDP5290 are the notebook, tablet accessories i.e., adapters (dongles), docking stations

and other AV accessories.
