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
DisplayPort 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 daughter card interface connector to connect the CCG2 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 USB Type-C Redriving Switch controlled by the CCG2 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 CCG2 device. This CCG EVK base board along with the CCG2
daughter card helps to convert any desktop or notebook PC with legacy USB ports to operate as a Type-C USB host.

Description
Power
The 24V input provided to the hardware is converted into the voltage to be provided on
the Type-C port using a PMIC. The output voltage of the PMIC is controlled by CCG2.
Power can also be consumed from Type-C connector for dead battery functionality.
Note:
The DC power adapter provided with the kit can support only up to 2.7A (at 24 V).
This kit will not work with 5V DC power adapters.
