Realtek SuperSpeed USB (USB 3.0) Hub Controllers Achieve USB-IF Certification


HSINCHU, Taiwan – March 13, 2013 – Realtek Semiconductor Corp. (Taiwan Stock Exchange: 2379.TW), one of the world’s largest IC design houses and a market leader in USB interface application technology, today announced the Realtek SuperSpeed USB (USB 3.0) hub controller (RTS5401) has passed USB 3.0 compliance and certification testing by the USB Implementers Forum (USB-IF).

“The USB-IF is pleased that Realtek has achieved certification for its SuperSpeed USB hub controller (RTS5401),” said Jeff Ravencraft, President & COO, USB-IF. “Realtek is a USB-IF member company dedicated to USB device standardization, and their efforts support the USB-IF’s mission to expand the SuperSpeed USB ecosystem”.

As the SuperSpeed USB market continues to grow at a rapid pace, hub solutions are needed to conveniently manage multiple consumer devices using USB 3.0. Realtek SuperSpeed USB hubs provide a flexible connection between the host and peripheral devices, with no sacrifice in transmission performance.

The Realtek RTS5401 is an advanced USB 3.0 hub controller with up to four downstream ports and with USB Battery Charging v1.2 support. The hub is backward compatible to USB 2.0 and USB 1.1. The System-on-a-Chip (SoC) successfully integrates a Switching Regulator and Low Dropout Regulator so that low-power consumption and a simplified BOM can be realized. Additionally, the RTS5401 integrates battery-charging controller logic that enables Dedicated Charging Port (DCP) and Charging Downstream Port (CDP) functionality as defined in the USB Battery Charging v1.2 specification and adds support for vendor specific, e.g., Apple, charging modes.

“We are proud to announce Realtek is one of the world’s first SuperSpeed USB (USB 3.0) hub controller chip vendors to receive USB-IF certification” said Realtek’s Vice President and Spokesman, Jessy Chen. “Our products offer high integration, high performance, and high adaptability. We have focused on every aspect of the user experience, as well as helping our customers to rapidly accelerate their design flow, and provide a substantial reduction in cost alongside an increase in available features”.

Realtek’s RTS5401 USB 3.0 hub controller is a competitive solution for any USB 3.0 hub application, and greatly helps reduce system design cost and time to market.
