Cadence IP Subsystem for USB Type-C and DisplayPort 

Are you prepared for the market’s shift to the USB Type-C™ specification? It appears that every USB device will be converted to the new connector to provide users the single cable experience they desire. But enabling a plug-and-play USB Type-C solution is no picnic. With data rates up to 10Gbps and up to 100W of power, USB Type-C is the new connector for exciting next-generation products. Add in DisplayPort support via USB Alternate Modes (Alt Modes), and the design challenges become extremely complex.

Get to market faster and with higher confidence using the Cadence® IP subsystem for the USB, USB Type-C, USB Power Delivery, and DisplayPort specifications.

Our IP subsystem (Figure 1) features pre-verified components, including a port controller IP that integrates USB Type-C, USB Alt Modes, and USB Power Delivery. The subsystem, which enables development of single-chip solutions that combine video, audio, USB, and up to 100W of power delivery on a single external connector, includes:

  • A connector-agnostic USB controller
  • A DisplayPort 1.3 TX controller
  • A 6G multi-protocol SerDes PHY
  • A USB Type-C Port Controller
  • Drivers for embedded systems and Linux OS

The USB Type-C Revolution

The USB Type-C Cable and Connector Specification, as illustrated in Figure 1, supports:

  • Reversible plugs with two-way insertion; the host and device connectors are the same
  • Higher data rates, up to 10Gbps for USB Type-C 3.1 Gen2
  • Increased power, up to 100W through support for the USB Power Delivery 2.0 specification
  • Bi-directionality, so that devices can provide and consume power
  • Scalable power charging, which means that power consumption may dynamically change depending on the application’s needs
  • Eventual replacement of other connectors by using USB Alt Modes

The Need for PHY Flexibility

As a universal connector, a USB Type-C design would need to support multiple protocols and different power delivery mechanisms. For chip developers, PHY flexibility is key, in order to support a wide electrical specification range, particularly on the equalization side.

Type-C Port Controller

USB Type-C Port Controller is a new piece of IP designed to facilitate support for both Power Delivery and Type-C Alternate Mode specifications. Cadence USB Type-C Port Controller provides control over current operation mode over the Type-C cable, enabling USB-only, USB/DP or DP-only modes of operation, as well as provides signals to external Power Management IC that supports Power Delivery specification and delivers up to 100W of power over Vbus.

Supporting the DisplayPort Specification 

With video so prevalent in today’s electronic devices, the ability for USB Type-C connectors to connect to displays is an important development. Designing USB Type-C applications with support for the DisplayPort standard comes with two key challenges: interoperability and compliance. 

Pre-verified IP blocks integrated into a subsystem can help you avoid the time and effort required to verify otherwise separate components and ensure that they will work well together. That’s why Cadence’s IP subsystem for USB Type-C can help you stay on top of the market shift to a single universal cable for charging, data transfer, and video output.
