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.
