Hi,
CCG3 is USB Type-C Power Delivery controller, which is can handle all of cases based on Type-C SPEC. Meanwhile, this Chip is also a MCU. If you would like to add a TCPM as counter/PWM/Timer, It is okay. Please kindly notice, by default, not all of CCG3 chips is pre-programmed full-featured firmware. You could refer Order Information of CCG3 datasheet.
If you would like to develop CCG3 firmware, below SDK is good for you.

Hi,LisaZ.I'm going to design a typeC to Displayport+USB3.0 typeA Dongle.
First question is,on the CCG3 EVM CY4531,Can I input the video on J3 typeC connector and output video on J4 connector to a legacy displayport monitor.
Another question is if I use the part CYPD3120-40LQXIT in our design,how to connect USB2.0 DP/DM to the type c port in order to fulfill firmware upgrade.Please see the attachment,which one is right?

Hi,
1. You cannot use CY4531 kit as it has Parade USB host & DP source mux and you are designing a sink device. CYPD3120 dongle example project is closer to your design.
2. You should connect as in option 1. USB Billboard device should be connected under the DS of Hub.

Muthu

Hi ,
Block diagram #1 is correct.
I have a blog (The difference is the USB2.0 can be USB2.0 host and device with the blog's design) with a hardware schematic, you can take a look. CCG3 Type-C receptacle DRP Reference Design (Power source & DisplayPort Sink)
