Chrontel’s CH7211A is a low-cost, low-power

semiconductor device that translates the DisplayPort

signal to HDMI/DVI through the USB Type-C connector.

This innovative USB Type-C based DisplayPort receiver

with an integrated HDMI Transmitter is specially

designed to target the USB Type-C to HDMI converter,

adopter and docking device. Through the CH7211A’s

advanced decoding / encoding algorithm, the input

DisplayPort high-speed serialized multimedia data can be

seamlessly converted to HDMI/DVI output.

The CH7211A’s DP/eDP receiver is compliant with the

DisplayPort Specification 1.3 and Embedded DisplayPort

(eDP) Specification version 1.4. With sophisticated

DisplayPort signal detection and the Lane Swap/AUX

polarity inversion logic, the CH7211A supports USB

Type-C cable plug orientation switch. With internal

HDCP key Integrated, the device support HDCP 2.2

specifications. In the device’s receiver block, which

supports four DisplayPort Main Link Lanes input with

data rate running at 1.62Gbps, 2.7Gbps or 5.4Gbps, and

converted the input signal to HDMI output up to

4Kx2k@60Hz. Leveraging the USB Power Delivery

control logic, the USB billboard module for USB device

indentify and DisplayPort’s unique source/sink “Link

Training” routine, the CH7211A is capable of instantly

bring up the video display to the HDMI/DVI TV/Monitor

when the initialization process is completed.

The CH7211A also supports up to 8-channel audio input

from either DP Rx or SPDIF port and output from HDMI

Tx with sample rate up to 192 KHz. Available audio

bandwidth depends on the pixel clock frequency, the

video format timing, and whether or not content

protection re-synchronization is needed.

With sophisticated MCU and the embedded EEPROM,

CH7211A support auto-boot and EDID buffer.

Leveraging the firmware auto-loaded from the embedded

EEPROM, CH7211A can support DP input detection,

HDMI connection detection, and determine to enter into

Power saving mode automatically.
