CH7216A中文资料Video Converter数据手册Chrontel规格书

描述 Description

Chrontel’s CH7216A 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 CH7216A’s advanced decoding / encoding algorithm, the input DisplayPort high-speed serialized multimedia data can beseamlessly converted to HDMI/DVI output. The CH7216A’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 CH7216A 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 CH7216A is capable of instantly bring up the video display to the HDMI/DVI TV/Monitor when the initialization process is completed.With sophisticated MCU and the embedded EEPROM,CH7216A supports auto-boot and EDID buffer.Leveraging the firmware auto-loaded from the embeddedEEPROM, CH7216A can support DP input detection,HDMI connection detection, and determine to enter into Power saving mode automatically.
