Single-chip DisplayPort-to-VGA converter device

The STDP3100 from ST Microelectronics is single-chip DisplayPort-to-VGA converter IC.
This chip enables DisplayPort-based desktops, workstations and notebooks to connect to legacy analog VGA monitors and projectors. STDP3100 packs a DisplayPort input, VGA output, and supporting functions into a single chip. These adapters will be inserted between the new DisplayPort notebook PCs and the large installed base of legacy monitors and projectors. This convenience allows consumers and enterprises to upgrade monitors and projectors at a later date. The STDP3100 can also be embedded in notebook PCs, and docking stations as their chip sets transition to DisplayPort.

DisplayPort supports the color rendition and pixel resolution required for larger screen sizes allowing PC users to watch high-quality multimedia content from Blu-ray players, Internet television, digital cameras, and high-definition gaming at WQXGA (2560 x 1600) and FHD 120Hz resolution. Also DisplayPort is an evolving, open standard, architected to scale upwards for today's fastest high-definition data rates, supporting bandwidth up to 10.8Gbit/s per link.

The STDP3100 supports a 2-lane DisplayPort receiver compliant with the DisplayPort version 1.1a standard. This supports 1080p high-definition video, on 1920 x 1200 (WUXGA) displays capable of displaying over a billion colors. The STDP3100 consumes low power and has a 20mW stand-by mode to help designers meet initiatives such as the International Energy Agency's 1-W Plan.
ST has already demonstrated interoperability with DisplayPort PCs, notebooks, and graphics cards from major vendors.
