HDMI Alt Mode over USB-C solution makes direct connection

Cypress Semiconductor has launched a complete solution for USB-C to native HDMI connections without adapters or converters. Based on Cypress EZ-PD™ USB-C controllers, the solution allows next-generation laptops, smartphones, tablets, digital cameras and other HDMI-enabled sources with USB-C connectors to connect directly to HDMI-enabled displays, including HD and 4K televisions, using a simple USB-C to HDMI cable.

EZ-PD controllers now support HDMI Alternate Mode for USB Type-C, along with USB Type-C standard support for audio, video and data protocols, as well as USB Power Delivery (PD) for fast charging.

All HD and 4K televisions include HDMI connections, but connecting non-HDMI-enabled source devices requires adapters or converters that do not enable all native HDMI features. With the Cypress HDMI Alternate Mode solution, source device manufacturers can now use native HDMI features via USB Type-C connectors.

“At Panasonic, we viewed the versatility of USB-C as an opportunity to expand the connectivity of our HDMI-enabled displays, and we worked closely with Cypress and their USB-C experts to support HDMI Alt Mode,” said Naoshi Usuki, research and development director at Panasonic.

“Our HDMI alt mode solution adds to Cypress’ track record of industry firsts for USB-C and power delivery, thanks to the programmability of our EZ-PD controllers and years of USB know-how,” said Ajay Srikrishna, vice- president, wired connectivity business unit, Cypress. “After collaborating with Panasonic to support the HDMI Alternate Mode, we moved quickly to develop our solution and demonstrate it in time for CES.”

“The HDMI Alt Mode for USB-C will result in more smartphones, tablets and laptops incorporating HDMI audio and video technology over the USB-C connector, which will in turn help add to the nearly six billion HDMI devices that have shipped worldwide,” said Rob Tobias, president, HDMI Licensing Administrator, Inc. “We are pleased that Cypress has swiftly brought their HDMI Alt Mode solution to the market so developers can implement this user-friendly capability for consumers.”

Cypress’ EZ-PD CCG3 controller offers integration that minimises bill-of-material costs and helps simplify design, replacing multiple discrete components with a single-chip solution. The EZ-PD portfolio of USB-C controllers also includes CCG1, the world’s first programmable USB-C controller, CCG2, the market’s smallest programmable USB-C solution, and CCG4, the world’s first two-port USB-C solution. The EZ-PD portfolio was the first to support the latest USB PD 3.0 specification, which enables more robust end-to-end power delivery and charging solutions for laptop and mobile devices.

The USB Type-C standard is gaining rapid support with electronics manufacturers by enabling slim industrial designs, easy-to-use connectors and cables, the ability to transmit multiple protocols and deliver up to 100W of power. The 2.4-mm-high connector plug is significantly smaller than the current 4.5-mm USB Standard-A connector.
