CS5211 Design EDP to LVDS Convert the reference circuit or EDP to LVDS The adapter board reference circuit is shown below ：

CS5211 Design EDP to LVDS Converter or EDP to LVDS The design characteristics of the adapter plate are as follows ：

CS5211 Will serve as a DP or eDP The receiver device appears in the video source , And will serve as LVDS Display panel LVDS Source device . The device is a fully integrated solution , No external is required CPU、 Memory 、 Clock reference or voltage regulator .CS5211 Can be configured to slave from the display DDC Channel or connect from to CS5211（ Provide I2C host ） External options ROM Read EDID. external ROM It can also include configuration code , To customize equipment operation and interface timing .CS5211 Provide power on sequence of display panel and backlight control , Include PWM Generate . Backlight characteristics can be obtained by using eDP v1.2 DPCD Control register DP AUX Control the video source on the channel . perhaps , The video source can provide a backlight control signal to CS5211,CS5211 Gate it for panel power up sequencing , Alternatively, the video source can bypass the device and directly control the backlight of the panel .
