NAME
GND / TMDS_GND
ESD Level DESCRIPTION
N/A
GND reference.
Note 1: These 2 pins need to be connected together in-line on the PCB. See recommended layout diagram.
Note 2: This output can be connected to an external 0.1μF ceramic capacitor/pads to maintain backward compatibility with the
CM2020.
Note 3: Standard IEC 61000-4-2, C_DISCHARGE=150pF, R_DISCHARGE=330Ω, 5V_SUPPLY and LV_SUPPLY within recommended
operating conditions, GND=0V, 5V_OUT (pin 38), and HOTPLUG_DET_OUT (pin 20) each bypassed with a 0.1μF ceramic
capacitor connected to GND.
Note 4: Human Body Model per MIL-STD-883, Method 3015, C_DISCHARGE=100pF, R_DISCHARGE=1.5kΩ, 5V_SUPPLYand
LV_SUPPLY within recommended operating conditions, GND=0V, 5V_OUT (pin 38), and HOTPLUG_DET_OUT (pin 20)
each bypassed with a 0.1μF ceramic capacitor connected to GND.
Note 5: These pins should be routed directly to the associated GND pins on the HDMI connector with single point ground vias at the
connector
