Datasheet Brief

MCDP28x0

1.

Description

The MCDP28x0 is a power-optimized DisplayPort1.2a-to-HDMI2.0b converter device targeted for

desktop/mobile PC motherboard-down applications and for DP or USB type-C adaptor (dongle, docking

station) applications. This device functions as a level shifter as well as an active protocol converter.

In level shifter mode, the device functions as a PHY repeater with optional jitter removal capability. This

operating mode provides a low-power means of using an AC-coupled TMDS signal from a dual mode DP

(DP++) source to be repeated to the HDMI output. The maximum TMDS character clock frequency in this

mode is limited to 340 Mchar/s (per HDMI1.4b specification).

In Protocol Converter (PCON) mode, MCDP28x0 functions as a DP branch device receiving AC coupled

DisplayPort stream and converting it to HDMI output. The maximum TMDS character clock frequency

supported in this mode is up to 600 Mchar/s (as per the HDMI2.0b specification).

The MCDP28x0 operates with two power supply voltages: 1.2 V and 3.3 V. It consumes:

•

100 mW in PHY analog repeater mode

•

412 mW in protocol converter mode

•

0.1 mW in connected standby mode (1.2 V power rail disabled)

The MCDP28x0 has a DisplayPort1.2a dual-mode receiver and HDMI2.0b transmitter. The upstream

main link can receive DP input at HBR2 rate over 4 lanes and AC-coupled TMDS signal up to

340Mchar/s. It supports DP SST stream on its main link and Manchester-coded AUX signaling or native

3.3 I2C signaling as the side band channel with the DP++ source. The downstream HDMI TX port is

HDMI2.0b specification compliant.

The MCDP28x0 is capable of supporting Ultra High-Definition video formats, resolutions as high as 4096 x

2160@60 Hz. It supports RGB/YCbCr video color formats with a color depth of 16 bpc (or 48 bits per

pixel) as long as it fits within the DP1.2a and HDMI2.0b link rate. In addition, this device also supports

pixel encoding conversion from YCbCr444 to YCbCr420 and YcbCr420 pass-through from a DP input to

an HDMI output. High Dynamic Range (HDR) with deep color up to 12bpc at 4Kp60Hz is supported

through the conversion of YCbCr444 CVT timing over DP link with horizontal expansion to YCbCr420

CEA timing on the HDMI TX output.

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

with HDCP 1.x content protection for the upstream DP interface and HDCP2.2 for the downstream HDMI

interface. It also operates as an HDCP1.x repeater between the source and the sink. In addition, it

conforms to the secure communication protocol specified in the Intel “LSPCON Security Requirements
