Cypress 7-port USB-C hub controller combines five chips in one
The programmable EZ-USB HX3PD hub controller simplifies USB-C dock system designs by integrating the functionality of five chips into one. This lowers the bill-of-materials (BOM) and cuts board size by half for notebook and tablet docking stations, monitor docks and multi-function USB-C peripherals.
USB-C docks have been complex to design, requiring two USB hubs to support internal and external connections, a dedicated controller for every USB-C port that supports USB PD charging, along with a USB billboard and USB-C bridge controller to report operating status and connection failures. The EZ-USB HX3PD hub controller simplifies system design by integrating these functions in a 12 x 12 mm package.
The controller includes a 7-port, 10-Gbps USB 3.1 Gen 2 hub, two USB-C ports with USB PD 3.0 charging at 100W, and a dock management controller with support for secure firmware downloads. Programmability enables designers to update USB-C and USB PD specifications and resolve interoperability issues, while a configurable USB PHY improves signal quality to meet and exceed USB compliance requirements.
“Our new HX3PD hub solution brings 10-Gbps performance to our leading portfolio of USB hubs for docking solutions, which includes HX3 and HX3C,” said Ajay Srikrishna, vice president of Cypress’ Wired Connectivity Business Unit. “The controller leverages our expertise in USB-C and USB Power Delivery to provide a highly-integrated solution, continuing our long track record of being first to market with USB-C solutions and extending our leadership in SuperSpeed USB.”
The HX3PD is sampling with production in the third quarter of 2018 in a 192-ball BGA package.
