Chrontel releases two chips for new DisplayPort standard

SAN JOSE, USA: Chrontel, a leading provider of video interface technologies, today announced two new devices that will help computer and display manufacturers as they navigate the transition from LVDS to DisplayPort.

Chrontel’s new CH7508 is a timing controller (TCON) that converts DisplayPort signals into mini-LVDS for display manufactures using mini-LVDS technology to drive TFT panels. The new CH7509 converts DisplayPort signals into LVDS so that computer processors using the new DisplayPort output can also maintain compatibility with LVDS displays.

The CH7508 is targeted at display manufacturers that wish to continue leveraging their extensive investment in mini-LVDS electronics, which control the internal column and row drivers that control display pixels.

By integrating a CH7508 into their display design, a panel can be upgraded for DisplayPort compatibility while maintaining internal mini-LVDS designs for timing control. The CH7508 supports panel resolutions up to WSXGA (1680 x 1050), and is capable of handling DisplayPort link rates up to 2.7Gb/s.

The CH7509 is targeted at computer motherboard manufacturers that have transitioned to processors that utilize DisplayPort video outputs exclusively.

By integrating a CH7509 into their motherboard design, these systems can maintain compatibility with the millions of external displays in the market that exclusively use LVDS inputs. The CH7509 supports panel resolutions up to WSXGA (1680 x 1050), and is capable of handling DisplayPort link rates up to 2.7Gb/s.

"Managing technology transitions is a delicate task for system designers," said Dr. David Soo, Chrontel President and CEO. "It is economically important for computer OEMs to maintain compatibility with the large installed base of LVDS displays, even as they begin to use new processors that have replaced LVDS outputs with DisplayPort.

"Display OEMs need to maximize life cycle ROI for their well-established mini-LVDS designs. Even today, many display OEMs are migrating RSDS display designs to mini-LVDS due to improved EMI performance, lower pincounts and reduced cost. Chrontel’s new duo of DisplayPort-to-LVDS conversion devices helps both computers and displays manufacturers achieve maximum cross-compatibility and profitability."

Developed as a replacement for the widely used LVDS standard, DisplayPort handles video data transmissions between a computer’s CPU or graphics controller and external display panels. DisplayPort handles larger display resolutions than the older LVDS standard.

Chrontel CH7058 samples are currently available, and production volumes will be available in July. The device is offered in a 64-pin QFN package, priced at USD 2.00 / each in 10,000 piece quantities.
