USB Type-C multiport minidock reference design speeds development

August 12, 2016 // By Julien Happich
Texas Instruments has introduced a multiport USB Type-C and Power Delivery (PD) minidock reference design that provides audio, USB data, power and video support.

The reference design can be powered by a traditional power adapter, USB Type-C adapter or notebook computer, offering end users flexible, intelligent functionality. It provides a fully tested, verified plan for a 2- by 4-inch dock, at least 50 percent smaller than existing docking solutions.

At the core of the USB Type-C and Power Delivery Minidock with Video and Charging Support Reference Design (TIDA-01243) is the TPS65982 USB Type-C and PD controller. The TPS65982 enables dual-role port USB Type-C functionality, capable of delivering 60 watts of power and supporting DisplayPort Alternate Mode and USB data transmission. In addition, the design features the TPS65986 USB Type-C and PD controller, HD3SS3212 SuperSpeed multiplexer, TUSB321 dual-role port controller and HD3SS460 Alternate Mode multiplexer, which work together to provide dual-role port capability for power, data and video transfer.

The design allows for autonomous PD negotiation for both source and sink, eliminating the need for an external microcontroller. By combining the highly integrated TPS65982 with other USB Type-C components in an optimized circuit, the minidock reference design allows engineers to develop up to 50 percent smaller docking stations compared to other designs available on the market with similar, comprehensive features. What's more, the minidock also supports USB 3.0 or 4K resolution video and digital audio through various output options.

The minidock TI Designs reference design (TIDA-01243) is now available for download.
