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.
