Silicon Image Inc. has announced two new VastLane HDMI transmitter chips that enable PC manufacturers to drive their digital output to PC monitors and HDTVs from a single transmitter.

The VastLane SiI1392-3 and VastLane SiI1932-3 HDMI transmitters promise blazing-fast performance of up to 340MHz or 10.2Gbps, letting them support monitor resolutions up to WQXGA (2560 x 1600 pixels) or HDTV resolutions up to 1440p. These products can drive the biggest, highest-resolution PC monitors on the market with a single-link solution, the company said. The previous generation of HDMI chips for PCs operated at up to 165MHz, which limited them to monitor resolutions of UXGA (1,600 x 1,200 pixels).

Silicon Image said it is delivering the components needed to strengthen the market leadership of HDMI in the PC space, building upon HDMI's current position as the de facto standard digital interface for HDTVs and high-definition CE products.

The new devices let PC makers use a single digital transmitter to connect to the large and rapidly-growing installed base of PC monitors with DVI inputs and HDTVs with HDMI inputs, along with future PC monitors expected to incorporate HDMI. These transmitters handle a broad range of PC applications ranging from corporate desktop PCs to home media PCs and notebook PCs to retail graphics cards.

"Silicon Image is enabling PC manufacturers to realise the benefits of HDMI with HDMI transmitter solutions designed for all PC sources," said Dale Zimmerman, VP of worldwide marketing at Silicon Image. "These products bring cost-effective, high-performance HDMI functionality to a variety of PC platforms, including motherboards with integrated graphics chipsets, notebook PCs and discrete graphics cards. PCs using these transmitters will have truly universal connectivity with the estimated 150 million DVI and HDMI monitors and TVs already in the market."

PC-to-HDTV transmission
PCs with HDMI connectors allow consumers to transmit the highest-quality premium digital audio and video content, such as high-definition movies from HD-DVD or Blu-ray Disc drives and HDTV tuners, to HDTVs and other displays.

The VastLane SiI1932-3 supports a Transition Minimised Differential Signaling (TMDS) input interface from discrete GPUs, while VastLane SiI1392-3 supports Intel's SDVO interface with integrated graphics controller chipsets. Because HDMI is backward compatible with DVI, these transmitters give PC makers the maximum flexibility of being able to interface to any digital display, from existing DVI LCD monitors, HDTVs and projectors to future low-cost all digital PC monitors with DVI or HDMI inputs. In addition, PCs integrating these transmitters can be designed to meet Windows Vista Premium requirements and to be fully compliant with the latest High-bandwidth Digital Content Protection (HDCP) 1.2 specification to transmit premium HD content.

In addition to adding unprecedented TMDS high-bandwidth performance, the new transmitters enable system-level cost reduction compared to currently-available HDMI solutions by integrating functions that normally require a discrete MCU in addition to the discrete transmitters.

Interoperability testing of HDMI products is available today through the Simplay HD Testing Program operated by Simplay Labs LLC, a wholly-owned subsidiary of Silicon Image. The Simplay HD Testing Program helps consumers identify high-definition components, such as HDTVs and next-generation DVD players, that will work together to provide a consistent "plug-and-play" user experience and to maximise users' access to premium high-definition content. Products bearing the Simplay HD logo have undergone testing related to HDMI and HDCP specifications, as well as compatibility testing with a suite of other devices that have been Simplay HD verified.

The VastLane SiI1392-3 and VastLane SiI1932-3 are packaged as 64-pin Pb-free QFNs and are currently available for sampling.
