9.2.2.2 Detailed Design Procedure

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. Pull-up resistors to 5 V must be placed on the source side DDC clock and data lines according to the HDMI2.0 Standard. A weak pull down resistor should be placed on the source side HPD line. This is to ensure the source can differentiate between when HPD is disconnected or at a high voltage level. The AUX_SEL and Dx_SEL control pins should be set according to the application and desired muxing.
