All VCC pins can be tied to a single 3.3-V power source. A 0.01-μF capacitor is connected from each VCC pin
directly to ground to filter supply noise.
Standard TMDS terminations are integrated on all TMDS inputs. External terminations are not required. Each
input channel contains an 8-dB equalization circuit to compensate for cable losses. The voltage at the TMDS
input pins must be limited per the absolute maximum ratings. An unused input should not be connected to
ground as this would result in excessive current flow damaging the device. TMDS input pins do not incorporate
failsafe circuits. An unused input channel can be externally biased to prevent output oscillation. The
complementary input pin is recommended to be grounded through a 1-k
resistor and the other pin left open.
