LVDS to DisplayPort converter ICs compatible with WUXGA resolutions

Chrontel has announced two new devices for computer and display manufacturers converting from legacy LVDS to the emerging DisplayPort standard for high-speed, high-resolution displays. Chrontel's new CH7510 is a timing controller (T-CON) used in display panels to convert DisplayPort input signals into mini-LVDS outputs that directly drive row and column pixel data on LCDs. The new CH7511 is used in notebook computers to convert DisplayPort input signals into LVDS, which is still widely used to drive video signals across the notebook's hinge to the computer display.

Both devices are product updates of Chrontel's popular CH7508 and CH7509 devices, which were announced in May 2010. The CH7510 and CH7511 are now compatible with WUXGA display resolutions (1920 x 1200 pixels at 60Hz refresh rates), while the CH7508 and CH7509 support WSXGA+ resolutions (1680 x 1050). The CH7510 and CH7511 are compliant with DisplayPort (DP) version 1.1a and embedded DisplayPort (eDP) standard version 1.2, and both devices support link rates up to 2.7Gb/s.

"DisplayPort is clearly the video interface standard of the future. Intel, AMD and other major technology companies have stated their plans to phase-out LVDS," said Dr. David Soo, Chrontel President and CEO. "At the same time, many monitor manufacturers have a significant investment in LVDS technology, and the cost of LVDS displays remains very competitive in the marketplace. Chrontel's new devices will help our customers make a smooth, profit-maximizing transition to DisplayPort."

Developed as a replacement for the widely used LVDS standard, DisplayPort handles video data transmissions from a computer's CPU or GPU to internal and external display panels. Major CPU vendors have publicly announced their plans to eliminate LVDS outputs from their product lines by 2013. The CH7511 DisplayPort Receiver / LVDS Transmitter enables computer designers that use new CPUs or GPUs with DisplayPort outputs to maintain compatibility with display panels already designed with LVDS inputs.

Mini-LVDS is a low-voltage, low-EMI version of LVDS that is used to drive row and column data to the LCD module within a display panel. The CH7510 allows display OEMs to offer products that use an external DP interface, while leveraging their investment in legacy mini-LVDS electronics inside the LCD module. Although the DisplayPort specification allows for direct drive of LCD displays, many display OEMs can maximize cost effectiveness by continuing to use mini-LVDS to directly drive LCD panels.

Package: Both 7511 and 7510 in 68-pin QFN
Availability: Now in samples and volumes in Apr 2011
CH7511: USD 1.95 each in 10,000 piece quantities
