Chrontel’s CH7217A 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,

adapter and dongle device. Through the CH7217A’s

advanced decoding / encoding algorithm, the input

DisplayPort high-speed serialized multimedia data can be

seamlessly converted to HDMI/DVI output.

The CH7217A’s DP/eDP receiver is compliant with the

DisplayPort Specification 1.4 and Embedded DisplayPort

(eDP) Specification version 1.4. With sophisticated

DisplayPort signal detection and the Lane Swap/AUX

polarity inversion logic, the CH7217A supports USB

Type-C cable plug orientation switch. With internal

HDCP key Integrated, the device support HDCP 2.3

specifications. In the device’s receiver block, which

supports four DisplayPort Main Link Lanes input with

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

8.1Gpbs, 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 CH7217A is

capable of instantly bring up the video display to the

HDMI/DVI TV/Monitor when the initialization process is

completed.

The CH7217A also supports up to 8-channel audio input

from either DP Rx or SPDIF/IIS 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 ROM,

CH7217A supports auto-boot and EDID buffer.

Leveraging the firmware auto-loaded from the embedded

ROM, CH7217A supports DP input detection, HDMI

connection detection, and determine to enter into Power

saving mode automatically.
