Lattice Semiconductor claims the first superMHL products to deliver 4K 60fps RGB/4:4:4 video with concurrent USB 3.1 Gen 1 or Gen 2 data over the new USB Type-C connector; presented as a transmitter and receiver pair, it can deliver and receive 4K 60fps over a single lane, enabling a “PC experience” with USB Type-C devices.

The SiI8630 and SiI9396 is a low-power superMHL (Mobile high-definition Link) transmitter and receiver pair that can deliver and receive 4K 60fps over a single lane. , enabling a PC experience with USB Type-C devices.

SiI8630 targets the mobile/PC sector; it will 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.

SiI9396 is intended for mobile/PC accessories and displays : the 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 SiI9396 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, latice says, be able to connect to legacy MHL and future superMHL TVs, monitors, AVRs, Blu-ray Disc players, projectors, set-top boxes 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 at Lattice Semiconductor. “Other video solutions require four lanes to deliver 4K 60fps, which inhibits concurrent 4K video with USB 3.1 data.”

The SiI8630 and SiI9396 devices support:

UHD 4K 60fps 4:4:4 over a single lane

Improved electromagnetic interference (EMI) features

Concurrent USB 3.1 (Gen 1 or Gen 2) data

Seamless integration with USB Type-C products
