CH7211数据手册Chrontel中文资料规格书

描述 Description

Chrontel’s CH7211 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 CH7211’s advanced decoding / encoding algorithm, the input DisplayPort high-speed serialized multimedia data can be seamlessly converted to HDMI/DVI output. The CH7211’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 CH7211 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 CH7211 is capable of instantly bring up the video display to the HDMI/DVI TV/Monitor when the initialization process is completed.The CH7211 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 On Chip Flash, CH7211 support auto-boot and EDID buffer. Leveraging the firmware auto-loaded from Flash, CH7211 can support DP input detection, HDMI connection detection, and determine to enter into Power saving mode automatically.
