Utilizing UHD Video Output from Smartphones
Realizing Console-Grade Gaming Experience and Home Entertainment on 4K TVs

Lattice Semiconductor and MediaTek jointly announced today the launch of a high power-efficient reference design capable of driving 4K UHD through USB Type-C connectors. Lattice's USB Type-C port controller and MHL® transceiver can be easily used together with MediaTek's Helio™ X20, the world's first mobile processor featuring a Tri-Cluster™ CPU and 10 processing cores (deca-core). Lattice and MediaTek have been collaborating to develop next-generation low-power video reference designs for the rapidly growing 4K UHD market, resulting in the launch of this solution.

PDO Functionality for Seamless 4K Video Transmission and Fast Charging

Consumers generally desire longer battery life in their smartphones and other mobile devices, making it extremely important to provide high performance while consuming minimal power. Taking smartphones as an example, Lattice's SiI8348 MHL transmitter is connected to MediaTek's Helio X20 and handles seamless 4K video transmission, while the SiI7033 port controller manages MHL Alt mode configuration on USB Type-C along with PDO (Power Data Objects) configuration settings necessary for fast charging of smartphones.

Additionally, the SiI7033 port controller integrates switches needed to simultaneously support MHL and USB 3.1 connectivity through reversible Type-C connectors. In docks and accessories, Lattice's SiI7013 and SiI9396 port controllers configure MHL Alt mode and are used to convert from MHL to HDMI respectively to connect billions of displays worldwide.

C.H. Chee, Senior Director of Consumer Marketing at Lattice Semiconductor, stated, "MediaTek is a very important partner with whom we are collaborating to develop 4K video output technology for smartphones. Through this, users can enjoy console-grade gaming and home entertainment on the latest 4K UHD TVs," and added, "We are supplying industry-leading 4K video output solutions with the highest efficiency so that consumers can enjoy this connected world without battery concerns, allowing them to experience both aspects under optimal conditions."
