3.1 CCG EVK Base Board
The CCG EVK base board is an evaluation board equipped with a Type-C port, a SuperSpeed USB Type-B port, and a
Display Port interface. It is primarily intended as a demonstration board for notebook designs that house a Type-C
connector. The board also serves as a vehicle to evaluate the alternate modes for Type-C, using the DisplayPort demo as
an example.
3.1.1 Block Diagram
The block diagram of the CCG EVK Base board is shown in
It has an on-board Type-C connector for the USB-
PD interface and a CCG3 daughter card interface connector to connect the CCG3 daughter card. It also includes a
SuperSpeed USB Type-B port, and a Display Port connector to source video. The SuperSpeed USB signals and Display
Port signals are connected to the Type-C connector through a high-speed multiplexer controlled by the CCG3 device. A DC
power adapter provides input voltage to the onboard Power Management IC (PMIC). The output voltage from the PMIC can
be selected using two voltage selection lines, controlled by the CCG3 device. This CCG base board along with the CCG3
daughter card helps to convert any desktop or notebook PC with legacy USB ports to operate as a Type-C USB host.
