Embedded DisplayPort to LVDS Converter

2 Lane eDP input, Dual Link LVDS Output

The PS8615 is an Embedded DisplayPort™ to LVDS converter designed for PC’s that utilize a GPU with an Embedded DisplayPort (eDP™) output and a display panel that accepts an LVDS input.

The PS8615 will appear as a DP or eDP Sink device to the video Source, and will serve as an LVDS Source device to the LVDS display panel. The device is a fully integrated solution requiring no external CPU, memory, clock reference or voltage regulator. The PS8615 can be configured to read EDID from the display DDC channel, or from an option external ROM attached to the PS8615 (I2C master provided).  The external ROM can also include configuration code to customize device operation and interface timing. The PS8615 provides display panel power-up sequencing and backlight control including PWM generation. Backlight characteristics can be controlled by the video Source over the DP AUX channel using the eDP v1.2 DPCD control registers. Alternately, the video Source can provide the backlight control signals to the PS8615 which will gate them for panel power up sequencing, or the Source can bypass the device and control the panel backlight directly.
