Analogix and GRL Initiate Certification for AV Compatibility between Devices with USB-C Ports

By CIOReview | Wednesday, September 2, 2015

SANTA CLARA, CA: Analogix Semiconductor, a designer and manufacturer of semiconductors for the digital multimedia market and Granite River Labs (GRL), a provider of Engineering Services and Test Solutions announces the expansion of SlimPort Adopters Program (SAP) to include the USB Type-C connector.

The program offers SlimPort certification including signal quality pre-test for DisplayPort, HDMI and VGA interoperability testing to confirm the maximum display resolution with devices available in the market and functional testing of power, data, audio and video transfer. The program is available to any USB Type-C device manufacturer.

It ensures that mobile devices work with the USB-C accessories available in the market. This includes the first wave of USB-C devices such as Apple USB-C Digital AV Multiport Adapter and the Google USB Type-C to HDMI Adapter.

Accessory makers can ensure that products work along video source devices with USB-C connector to support DisplayPort Alternate Mode as well as with many smartphones, tablets and notebook computers that will support DisplayPort Alt Mode. DisplayPort Alternate Mode is the standard for sending video over the USB Type-C port since its adoption by 12-inch MacBook, Google Pixel 2 Chromebook and Microsoft after its recommendation in their New Guidelines for USB for Windows 10.

Testing is performed in the Analogix EasyHD Lab to address the interoperability issues in HDMI and DisplayPort devices. GRL is already able to certify devices with USB Type-C connectors and DisplayPort Alternate Mode support.

Once products receive certification, adopters will have access to marketing collaterals and technical support, receive listings on the websites and also be provided with the option to use the SlimPort trademark on their products to highlight the video-out capability.

“Most leading mobile device manufacturers and accessory makers are aggressively switching to USB-C connectivity and SAP is in place to provide cost efficient solutions for interoperability testing and compliance reporting. This is increasingly important as resolutions increase on mobile devices. With USB-C, DisplayPort supports 4K 60Hz and beyond simultaneously with USB3 data transfer. The SlimPort trademark signifies to the end user that the device interoperates with the leading products available in the market, and with other SlimPort devices,” says Andre Bouwer, VP, Marketing, Analogix.
