Equalizer Control. This pin allows the user to control the equalization level of the MAX3815. Connect
the pin to GND for automatic operation. Set the voltage to V

Characteristics for more information.
Loss-of-Clock Signal Output, LVTTL Open Collector. This pin asserts low upon loss of the input TMDS
clock from the cable.
Power-Down Input, LVTTL. This input allows the IC to be powered down to conserve power. Connect
high for normal operation. Pull low for power-down mode.
