Sunnyvale, Calif.Widespread adoption of the High Definition Multimedia Interface (HDMI) is taking hold in the worldwide PC market with many industry-leading PC makers and component manufacturers designing their products to include HDMI interfaces. As the PC continues to evolve into a media center, PC platforms such as motherboards with integrated graphics chipsets, notebook PCs and discrete graphics cards will require connectivity to HDTVs and must include HD and multimedia capabilities.
Silicon Image has positioned its HDMI products to play a critical role in the HDTV transition by bridging the content delivery gap between content providers and consumers. Indeed, the company is the first to market HDMI and DVI-HDCP transmitters designed specifically for PC platforms that interface seamlessly to discrete and integrated graphics controllers.
The company has started to sample the VastLane SiI1392-3 and SiI1932-3 transmitter chips that enable PC makers to drive their digital output to PC monitors and HDTVs from a single transmitter. The VastLane SiI1392-3 and SiI1932-3 let PC makers use a single digital transmitter to connect to installed base of PC monitors with Digital Visual Interface (DVI) inputs and HDTVs with HDMI inputs, along with future PC monitors expected to incorporate HDMI.
HDMI, which has been adopted as an audio/video interface by more than 300 makers of consumer electronics and PC systems worldwide, has become a de-facto standard for connecting home entertainment products.

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 SiI1392-3 and SiI1932-3 are the low-cost successors to the Sil 1390 and Sil 1930 transmitters. They are self-contained parts that don't require an external microcontroller or audio PLL for operation.
As a result, BOM savings is an estimated $1.40, according to the company.
The VastLane SiI1392-3 and SiI1932-3 can support data transmission speeds of up to 340 megahertz (MHz) or 10.2 gigabits per second (Gbits/s), letting them support monitor resolutions up to WQXGA (2560 x 1600 pixels) or HDTV resolutions up to 1440p. At 340-MHz, the HDMI transmitter chip allows single link support for higher resolution monitors, such as Apple's 2560X1600 Cinema Display. The previous generation of HDMI chips for PCs operated at up to 165 MHz, which limited them to monitor resolutions of UXGA (1600 - 1200 pixels).

In addition to providing very simple migration from the previous generation parts, Silicon Image has made using the VastLane SiI1392-3 and SiI1932-3 transmitters much easier because the SiI 1392 Tx implements all required operation codes to support the Intel SDVO HDMI specification, as well as its own Transmitter Programming Interface (TPI) specification.
Intel's SDVO interface specification is a high-speed serial data interface designed into Intel's latest PCI Express-enabled chipsets: the Intel 915G, 915GV, 910GL and 945G Express Chipsets. PC makers designing with these PCI Express Chipsets require SDVO-compliant HDMI transmitters to link the internal Integrated Graphic Device of a PCI Express chipset with external consumer electronics products that use the HDMI standard to receive and display high-definition video and audio content.
Both parts also support the HDMI HD Audio protocol.
The VastLane SiI1932-3 supports a TMDS (Transition Minimized Differential Signaling) input interface from discrete graphics processing units (GPUs), while the 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 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.
The VastLane SiI1392-3 and VastLane SiI1932-3 are packaged as 64-pin lead-free QFNs and are priced at $6.50 each in volume quantities.
