1. Description

The MCDP2900 is a power-optimized DisplayPort1.4a-to-HDMI2.0b converter, targeted for enabling USB

Type-C DP Alt mode on TVs, Game consoles and other consumer equipment as well as for mobile PC and

tablet accessory applications. This device functions as an active protocol converter with HDCP1.x/ HDCP2.3

repeater supporting HDR video quality for deep color media content playback.

MCDP2900 behaves as a DP branch device with a DP-to-HDMI transport protocol converter function and

allows a DP or USB Type-C source to drive an HDMI sink device. The maximum TMDS character clock

frequency supported is 600 Mchar/s (per HDMI2.0b specification).

The MCDP2900 operates with two power supply voltages: 1.2 V and 3.3 V. It consumes:

• 570 mW in protocol converter operation

• 11 mW sleep mode operation

The MCDP2900 has a DP1.4a receiver and an HDMI2.0b transmitter. The DP receiver supports up to

5.4Gbps/lane over 4 lanes. It supports DP SST transport format on its main link and Manchester-coded AUX

signaling as the side band channel. The downstream HDMI TX port is HDMI2.0b specification compliant.

The MCDP2900 is capable of supporting Ultra High-Definition video formats with resolutions as high as 4096

x 2160 progressive @ 60 Hz (4K2Kp60Hz). It supports RGB/YCbCr video color formats with a color depth of

16 bpc (bits per component or 48 bits per pixel) as long as it fits within the DP and HDMI link bandwidth.

This device also supports pixel encoding conversion from RGB or YCbCr444 to YCbCr420 and a YcbCr420

pass- through function. In addition, High Dynamic Range (HDR) with deep color up to 12bpc at 4Kp60Hz is

supported through the conversion of RGB/YCbCr444 over DP link to YCbCr420 on the HDMI output with a

horizontal expansion to CEA timings.

This device offers secure reception and transmission of high bandwidth digital audio and video content with

HDCP1.3 and HDCP2.3 content protection for the upstream DP interface. It also supports HDCP1.4 and

HDCP2.3 repeater function compliant to the latest CTS specification.

The MCDP2900 uses an external crystal of 27 MHz as a reference clock for its operation. An internal Power

On Reset (POR) circuit senses the voltage on the reset input and provides the chip reset during system

power-up. The device has an internal microcontroller with SPI, UART (debug only), and I2C system interface

signals. It uses an external 8Mbit SPI flash memory for storing a secure signed firmware image with fail-safe

recovery. Firmware update to the SPI flash is done securely through the DP AUX_CH or the I2C host

interface. The secure programming (In-System-Programming), secure boot and application FW signing

process uses RSA 2048-bit root and leaf public/private key pairs.
