Chrontel's CH7515 is a low-cost, low-power semiconductor device that translates the Embedded DisplayPort signal to the LVDS in form of RGB/YCbCr 4:4:4/YCbCr 4:2:2. This innovative eDP receiver with integrated 4 channel LVDS transmitters is specially designed to target the All-In-One PC and the notebook market segments. Leveraging the DisplayPort's unique source/sink \"Link Training\" routine, the CH7515 is capable of instantly bring up the video display to the LCD when the initialization process is completed between CH7515 and the graphic chip.The CH7515 is designed to meet the Embedded DisplayPort Specification version 1.2. The 4 eDP Main Link Lanes receiver supports input with data rate running at either 1.62Gb/s or 2.7Gb/s, and can accept digital RGB signal for LVDS output up to QSXGA 2560x2048@60Hz. With advanced 3D processing module integrated, The CH7515 can support up to 1920x1080@120Hz 3D display mode, with programmable emitter control signal and 3D LCD panel's backlight control signal output.The Backlight Enable control and the PWM are the two kinds of backlight control functions designed in the CH7515 Panel power control module. The brightness control commands sent through AUX Channel can be dynamically translated by CH7515 and converted into LCD backlight control signal. Alternatively, the brightness control commands can be input from the PWM in and GOIO pin of Backlight Brightness Control. The CH7515 will save the last setting of brightness level into the external BOOT ROM and restore it upon power up. The CH7515 can dynamically adjust backlight brightness according to video stream to save power consumption and it supports OSD display in this way.The CH7515 will immediately convert the Embedded DisplayPort signal to LVDS output after DisplayPort Link Training is completed. This feature can be achieved by loading the panel's EDID and the CH7515's configuration settings in the serial external BOOT ROM connected to the CH7515. During system power-up and upon completion of the DisplayPort Link Training through AUX Channel, CH7515 will generate LVDS signal according to the panel power-up timing sequencing stored in the external BOOT ROM.An advanced Power Management Unit (PMU) is incorporated in CH7515, which is specially designed to reduce power consumption in normal operation.
