San Jose, Calif.Chrontel announced the CH7507, a DisplayPort receiver IC with Integrated Timing Control (TCON) for use in notebook and netbook computer displays.
Developed as a replacement for the widely used LVDS standard, DisplayPort handles video data transmissions between a computer's CPU or graphics controller, across the hinge to the LCD screen in a notebook or netbook computer. As screen resolutions increase, DisplayPort offers performance capabilities that LVDS cannot match.
The Chrontel CH7507 satisfies DisplayPort specification version 1.1a, and supports 1440x900 display resolutions with 8-bit color depth, and 1680x1050 resolutions with 6-bit color depth, all at 60Hz refresh rates. And unlike LVDS, DisplayPort can operate at voltages below 2.5V, reducing power consumption. The low-power CH7507 devices are available in a 64-pin QFN package, and consume just 180mW.
The CH7507 combines a reduced swing differential signaling (RSDS) capability to interface directly with the video data transmitter, with a TCON to drive the source and gate LCD pixel array. The device integrates gamma correction and pixel dithering for improved display quality. Power consumption is optimized using the chip's dynamic refresh rate switching capability.
The CH7507 supports data rates up to 2.7Gb/s. The device integrates a brightness control function that manages LCD backlight modules. And specific ON/OFF sequences for different LCD panels can also be controlled through the CH7507's register map or programmed through the AUX channel by the transmitter.
Pricing: $1.60/ea. in 10,000-piece quantities.
Availability: Samples are currently available.
