USB Type-C DisplayPort Alternate Mode
This section introduces how to implement a DisplayPort Source based on USB Type-C DisplayPort
Alternate Mode. The demo includes two major parts: DisplayPort and USB Type-C.
For DisplayPort design, DisplayPort Intel FPGA IP is used to generate DisplayPort TX video. The
DisplayPort design is refer to the document :Arria 10 DisplayPort Design Example using on board
connector (TX Only).
For USB Type-C, system need to monitor the information sent from the USB Type-C Port
Controller CYPD3125 (EZ-PD CCG3). From the sent information, system can know whether the
plug-in device is a DisplayPort monitor and the DP lane number is 4 or 2, and system have to
configure the DisplayPort crossbar switch so the FPGA transceiver signals can be routed to the
type-c port correctly.
The Quartus Project USBC_DP_4K is designed for 4K monitor, and USBC_DP_FullHD is design
for Full HD Monitor. If your Type-C monitor only supports Full HD, please use the
USB_DP_FullHD for the demo setup.
System Block Diagram
shows the system block diagram for the DisplayPort Demo. When a Type-C monitor is
plugged into the Type-C Connector, the Type-C Port Controller (EZ-PD CCG3) will enable 5V
power for the monitor. When a Type-C device is plug-in or removed from the Type-C connector, the
CCG3 will notify FPGA through the IC2 interface. CCG3 will sends one byte data to 0 offset
address in the I2C Slave Port. The meaning of the data is shown in
. If attached device is a
DisplayPort monitor, then DisplayPort crossbar switch is configured so the transceivers signals are
routed to the type-c connector correctly.
For DisplayPort design, the Hot Plug Detect (HPD) causes the DisplayPort source to initialize the
link via AUX channel. The DisplayPort IP generates parallel Video data and FPGA transceivers are
used to serial the video data. For 4K video data, 4 TX transceivers are used with reference clock
270 MHz. For Full HD video data, 4 or 2 TX transceivers are used. The input video data for
DisplayPort IP is generated by VIP Test Pattern Generator II IP and VIP Clocked Video Output II IP.
In the system, a Nios II processor is used to control the DisplayPort IP. The Nios II Processor is
running on on-chip memory with 100Mhz.
