Bi-directional USB-C active cable reference design unveiled

Jan. 6, 2020
At CES 2020, Analogix has introduced Times Square Reference Design RD1011, billed as defining the industry’s first bi-directional USB-C active cable with integrated retimer technology.
New active cable architecture, featuring SRIS and LTTPR support, is positioned as a superior option for connecting display monitors, docking stations, and VR HMDs.

Analogix Semiconductor has announced the availability of its Times Square RD1011, a high-performance reference design defining a USB-C to USB-C active cable with bi-directional support, capable of connecting a USB-C source to a USB-C device across multi-meter distances.

Analogix says the RD1011's low bill of materials (BOM) cost comprises: a dual retimer architecture with connection via a 4 meter twisted-pair cable and one paddle card at each end of the cable to maximize length without sacrificing performance; a bi-directional solution for extending USB-C, USB 3.2 10 Gbps Gen2 or DisplayPort 8.1 Gbps HBR3 source output over long distances; an SRIS architecture for true USB 3.2 compliance, as well as transparent and non-transparent (LTTPR) architecture for DisplayPort 1.4a interoperability; a fully functional e-marker controller with Power Deliver (PD 3.0) handling USB-C power contract negotiation and SOP`/SOP`` messages.  

“We’re pleased to be further expanding our industry-leading signal conditioning technology to pertinent and fundamental applications,” commented Michael Ching, vice president of marketing at Analogix. “Times Square’s clever architecture will extend the system performance across a thin and powerful USB-C cable to display monitors, highly integrated docking stations, and VR HMDs.”

Leveraging Analogix’s expertise in high-speed signal management, USB-C port controller architecture, and proven SRIS and LTTPR retimer technology, the company says its RD1011 design offers best-in-class performance with superior interoperability and very low power consumption at under 1.5W.

“We see growing demand for USB 3.2 USB-C to USB-C active cables and Analogix’s reference design is the framework that enables such connections with optimal performance,” asserted Robert Lin, head of ABG US sales and support at Foxlink.

The RD1011 reference design is sampling now and product demonstrations are taking place during this week’s CES 2020, at the Analogix Exhibitor Suite 30-136 in The Venetian resort in Las Vegas. For more information visit
