STMicroelectronics N.V. (STMicroelectronics) has introduced new single-chip DisplayPort-to-VGA converter, STDP3100, to support in the rapid transition to DisplayPort as the display interconnect standard. The STDP3100 allows DisplayPort-based desktops, workstations and notebooks to connect to legacy analog VGA monitors and projectors. This will promote the uptake of the new high-performance digital-display interface by providing greater flexibility for equipment buyers and end users.
By consolidating a DisplayPort input, VGA output, and supporting functions into a single chip, the STDP3100 replaces current multi-chip solutions to enable smaller, lower power, cost-effective and reliable cable adapters. 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.
Current display interconnects between PCs and monitors are based on analog VGA or DVI standards. Neither standard fully supports the color rendition and pixel resolution required for larger screen sizes, which PC users are increasingly demanding. As a high bandwidth, secure, digital interface, DisplayPort overcomes these barriers, 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. Unlike VGA and DVI, 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 one billion colors. The STDP3100’s low power consumption allows designers the flexibility to draw power from the DisplayPort source, saving cost, size, and complexity while enhancing ease of use. In addition the device has a 20mW stand-by mode to help designers meet initiatives such as the International Energy Agency’s 1-W Plan. The STDP3100’s small 64-pin 10 x 10mm LQFP package enables it to be integrated into inline cable adapters, notebooks and docking stations. ST has already demonstrated interoperability with numerous DisplayPort PCs, notebooks, and graphics cards from major vendors, allowing fast design completion at low risk and low cost.
The STDP3100 is sampling in limited quantities now to lead customers; priced at $3.90 each in large volumes.
