Complete silicon and software solution for USB Type-C to DisplayPort adapters

A complete silicon and software solution for USB Type-C to DisplayPort adapters (dongles) has been announced by Cypress Semiconductor. The EZ-PD CCG1-based Type-C to DisplayPort Cable solution enables connectivity between a USB Type-C receptacle and a DisplayPort (DP) or Mini DisplayPort (mDP) receptacle, allowing emerging Type-C notebooks and monitors to be interoperable with older products. The Cypress Type-C to DP solution includes USB Billboard Device Class, which allows the adapter to communicate status to a host that does not support DP. The solution uses Cypress's EZ-PD CCG1 (CYPD1120) Type-C Port Controller to support DP as one of its Alternate Modes and the CY7C65210 Full-Speed USB 2.0 controller to support the USB Billboard Device Class. Cypress demonstrated that its Type-C to DP solution is interoperable with the Apple MacBook, the Google Chromebook Pixel and multiple other systems at the recently concluded VESA and USB-PD Interoperability events in Milpitas, California. "The market demand for USB Type-C is ramping quickly, and this will necessitate a strong demand for adapters to connect with older notebooks, monitors and other peripherals," said Ajay Srikrishna, vice president of the USB product line, Cypress. "Our EZ-PD CCG1-based Type-C to DisplayPort adapter solution is a comprehensive solution for this market. It is fully reversible and comes with reference schematics, firmware for the EZ-PD CCG1 and the Billboard Controller device, as well as a flashing tool for firmware updates." The USB Type-C standard is gaining rapid support with top-tier PC makers by enabling slim industrial designs, easy-to-use connectors and cables, the ability to transmit multiple protocols, and 100W power delivery (PD)-a significant improvement over the previous 7.5W standard. The Type-C standard's 2.4-mm-high connector plug is significantly smaller than current 4.5mm USB Type-A standard connectors. It also allows for transport of USB signals and PCIe or DP signals on the same connector, says the company.
