    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.
