DESCRIBE
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 2.2 specifications. In the
device’s receiver block, which supports four DisplayPort Main Link Lanes
input with data rate running at 1.62Gbps, 2.7Gbps, 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.
