The HD3SS215 is designed to operate with a 3.3 V power supply. Levels above those listed in the Absolute Ratings table should not be used. If using a higher voltage system power supply, a voltage regulator can be used to step down to 3.3 V. Decoupling capacitors may be used to reduce noise and improve power supply integrity. AC capacitors must be placed on the MainLink lines. Additionally, AC capacitors are placed on the AUXC lines. After the blocking capacitors, the AUXCp line must be pulled down weakly through a resistor to ground, and the AUXCn line must be pulled up weakly through a resistor to VDD. The voltage level of the control pins, AUX_SEL and Dx_SEL should be set according to the application and muxing desired. For a DisplayPort connector, the CONFIG1 and CONFIG2 pins should be pulled to ground through resistors. For Dual Mode adapter implementation, the CONFIG1 line may be used to perform cable adapter detection. The CONFIG2 line can be configured for an HDMI adaptor or left as a no connect for a DVI adapter. The CONFIG2 pin on the connector should be pulled up or left floating accordingly for Dual Mode adapter configuration.
