USB Type-C docking system design can halve solution size
Providing support for audio, USB data, power and video, a multiport USB Type-C and Power Delivery (PD) minidock reference design has been unveiled by Texas Instruments. This reference design can be powered by a traditional power adapter, USB Type-C adapter or notebook computer, offering end users flexible, intelligent functionality.
The new TI Designs reference design provides a fully tested, verified plan for a 2x4" dock, at least 50% 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 60W 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 MCU. The minidock also supports USB 3.0 or 4K resolution video and digital audio through various output options. In order to simplfy and speed engineers' design cycles, all ICs within the design are compliant with the current USB Type-C and PD standards.
The design combines the complete solution of TI USB Type-C and PD-compliant ICs, including port controllers, data multiplexers, DC/DC converters, load switches, FETs, signal conditioners and circuit protection, easing product selection and purchasing during design implementation.
The minidock design features the industry's most complete portfolio of USB Type-C-compliant products and resources. As a founding member of the USB Implementers Forum and with more than 20 years of experience engineering USB-compliant products, TI enables designers to deliver the most innovative end solutions built on a foundation of high-performance products.
The minidock TI Designs reference design (TIDA-01243) is now available for download. Additionally, an evaluation module allows designers to quickly evaluate and implement their minidock designs.
