Hello,

We are in the last design phase of our new ultrasound scanner.

On all of our previous ultrasound scanners we had a power input connector to charge the battery, few USB host connectors and a video output connector.  We just receive from the mechanical team a request to replace all of those connectors by a single USB Type-C connector.

We have some experience with USB 2.0 and USB 3.0 but we have no experience with USB Type-C and Power Delivery.

Our requirements for the USB Type-C connector are:

  • USB 3.0 host,
  • USB 2.0 host,
  • Display Port output,
  • VBUS 5 V / 500 mA source to power peripherals like a USB memory stick,
  • VBUS 15 V / 3 A sink to charge the battery.

Can you help us select the proper controller?

Do you know a reference design that meet the requirements of our system?

Thank you,

Best Regards,

Patrice

Hi Patirce,

The notebook application of CCGx can support all of requirements you have lists out. I could like to recommend you CCG5C CYPD5126, or CCG4 CYPD4126, or CCG3 CYPD3125 for your design. And you can refer application notebook for all of them.

For example, CCG5C, you can get high level schematic block diagram in the datasheet: (You just need change the TBT controller to MUX like PS8740B, and then wire to source of DisplayPort and USB host.)

For CCG4 is easy, since CCG4 have EVAL KITs on websites: It is based on CYPD4225 for dual port, but you can cut half of it and use CYPD4126 for it.

For CCG3 is the most easy for you, the CCG3 EVAL KIT can support all of requirements without any changes. The link:
