Bi-directional USB-C active cable can display more monitors

Signal conditioning technology from Analogix Semiconductor has been expanded with the addition of the Time Square RD1011 reference design for USB-C to USB-C active cable with true bi-directional support.

It has an integrated retime and a cable architecture with separate reference clock independent SSC (SRIS) and link training-tunable PHY repeater (LTTPR) support.  According to Analogix, it is capable of connecting a USB-C source to a USB-C device across multi-meter distances.

The RD1011 is claimed to have the highest interoperability, lowest power consumption at under 1.5W and lowest bill of materials (BoM) cost available today.

It has a dual retimer architecture with connection via a four meter twisted-pair cable and one paddle card at each end of the cable. This maximises length without sacrificing performance.

The bi-directional solution extends USB-C, USB 3.2 10Gbits per second Gen2 or DisplayPort 8.1Gbits per second HBR3 source output over long distances, while the SRIS architecture meets true USB 3.2 compliance and there is transparent and non-transparent LTTPR architecture for DisplayPort 1.4a interoperability.

An e-marker controller with Power Deliver (PD 3.0) handles USB-C power contract negotiation.

Vice president of marketing at Analogix, Michael Ching, said: “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 [head mounted displays].”

RD1011 is sampling now and product demonstrations are taking place during CES 2020 at Analogix Exhibitor Suite 30-136 in The Venetian, Las Vegas.

Analogix Semiconductor designs and manufactures semiconductors for the digital multimedia market, from portable devices such as smartphones, notebooks, and AR/VR head mounted displays, to large, high-definition TVs and high-end graphics cards. Analogix says it is the market leader in providing end-to-end interface connectivity semiconductor solutions for DisplayPort (its SlimPort brand), including high-speed signal conditioners and an industry leader in display panel controllers, such as low-power, high-speed timing controller solutions. The DisplayPort standard is an innovative, packetised digital interface for high-resolution video and audio that was developed by the Video Electronics Standards Association (VESA). SlimPort branded products are compliant with DisplayPort, Mobility DisplayPort (MyDP), and DisplayPort Alternate Mode over the USB Type-C connector.

Analogix display panel timing controllers offer the world’s lowest power, smallest packaging, and proprietary image enhancement to produce more accurate colours, thinner bezels and smoother frame rates on the latest high dynamic range (HDR) panels, says the company.
