SuperMHL transmitter & receiver deliver 4K 60fps video

The world’s first superMHL products for USB Type-C to deliver 4K 60fps RGB/4:4:4 video with concurrent USB 3.1 Gen 1 or Gen 2 data have been introduced by Lattice Semiconductor. The SiI8630 and SiI9396 are a low-power superMHL transmitter and receiver pair that can deliver and receive 4K 60fps over a single lane, enabling a PC experience with USB Type-C devices. 

The SiI8630 transmitter is able to seamlessly interface with HDMI 2.0 transmitters already integrated into the application processors used in the latest phones, tablets and notebooks. Since this part has an MHL switch, it enables a direct interface with a USB 2.0-enabled Type-C connector without the need for additional high-speed switches. The SiI8630, combined with the Si7033, offers a complete solution to deliver 4K 60 video with concurrent USB 3.1 Gen 1 data.

The SiI9396 receiver is suitable for MHL adapters and docks. When paired with the SiI7023 or SiI7033, MHL accessories can be designed to connect USB Type-C mobile and PC products to HDMI displays and USB devices such as keyboards, mice and external storage. The receiver can also be used in monitors, projectors and TVs to connect to MHL and superMHL sources, including mobile and PC devices with the USB Type-C connector.

USB Type-C products using these solutions will be able to connect to more than 750m legacy MHL and future superMHL TVs, monitors, AVRs, Blu-ray Disc players, projectors, STBs and automotive products.

“Our superMHL transmitters and receivers offer the lowest power, quick time to market, and the only solution to offer concurrent USB 3.1 data with 4K60 UHD video to address the growing number of productivity applications for mobile devices,” said Abdullah Raouf, Senior Marketing Manager, Lattice Semiconductor. “Other video solutions require four lanes to deliver 4K 60fps, which inhibits concurrent 4K video with USB 3.1 data.”
