1. These 2 pins need to be connected together in−line on the PCB.
2. This output can be connected to an external 0.1 mF ceramic capacitor, resulting in an increased ESD withstand voltage rating.
3. Standard IEC 61000−4−2, C_DISCHARGE = 150 pF, R_DISCHARGE = 330 W, 5V_SUPPLY and LV_SUPPLY within recommended operating
conditions, GND = 0 V and ESD_BYP (pin 37), 5V_OUT (pin 38), and HOTPLUG_DET_OUT (pin 20) each bypassed with a 0.1 mF ceramic
capacitor connected to GND.
4. Human Body Model per MIL−STD−883, Method 3015, C_DISCHARGE = 100 pF, R_DISCHARGE = 1.5 kW, 5V_SUPPLY and LV_SUPPLY within
recommended operating conditions, GND = 0 V and ESD_BYP (pin 37), 5V_OUT (pin 38), and HOTPLUG_DET_OUT (pin 20) each
bypassed with a 0.1 mF ceramic capacitor connected to GND.
5. These pins should be routed directly to the associated GND pins on the HDMI connector with single point ground vias at the connector.
