USB Type-C to HDMI/DVI/VGA adapter; and development kit

A dongle design for an interface adaptor; and a robust USB Type-C development kit, use Cypress’ EZ-PD CCG1 USB Type-C port controller and USB Billboard controller, to enable emerging USB Type-C products to communicate with older products.

A complete silicon and software solution for USB Type-C to HDMI/DVI/VGA adapter dongles, the EZ-PD CCG1-based USB Type-C to HDMI/DVI/VGA Adapter solution enables connectivity between a USB Type-C receptacle and an HDMI/DVI/VGA plug, allowing emerging USB Type-C notebooks to connect to an HDMI/DVI/VGA display. Cypress has also expanded its USB-Type C design support with the CY4501 CCG1 Development Kit (DVK), which enables designers to add USB Type-C to any system.

The Cypress USB Type-C to HDMI/DVI/VGA solution includes USB Billboard functionality, which allows the adapter to communicate status to a host that does not support DisplayPort (DP). This solution uses Cypress’s EZ-PD CCG1 (CYPD1120) USB Type-C Port Controller to support DP as one of its Alternate Modes, Cypress’s USB Billboard controller (CY7C65210) to support the USB Billboard Device Class, and MegaChips’ DP to HDMI/DVI/VGA protocol converter chip. Cypress says it has demonstrated that its USB Type-C to HDMI solution with power delivery (PD) is interoperable with the Apple MacBook, the Google Chromebook Pixel and multiple other systems, at USB-PD Interoperability events.

“With the rapid adoption of USB Type-C, the market is looking for fast ways to bring USB Type-C connectivity to products and for adapter dongles that enable connectivity with older products,” said Ganesh Subramaniam, Senior Director of the USB product line at Cypress. “Cypress's CY4501 CCG1 Development Kit demonstrates the ability of our EZ-PD CCG1 controllers to serve as a total USB Type-C solution by packaging the host, client and cable boards in a single kit for unmatched ease of implementation. Likewise, we designed our complete EZ-PD CCG1-based USB Type-C to HDMI/DVI/VGA Adapter solution to help customers get their dongles to market quickly.”

Cypress customers can pre-order the CY4501 CCG1 DVK online from the Cypress store. Based on Cypress’s EZ-PD CCG1 USB Type-C Port Controller, the kit serves as a platform to evaluate several features for USB Type-C with design examples and demonstrations of USB SuperSpeed, DisplayPort and Power
