Output Disable (Squelch) Mode uses TMDS Clock channel signal detection. When low voltage levels on the TMDS input clock signals are detected, Squelch state enables and TMDS output port signals shall disable; when the TMDS clock input signal levels are above a pre-determined threshold voltage, output ports shall return to the normal voltage swing levels. HPD_SINK Shut Down When HPD_SINK pin is floating or tie to GND, TMDS outputs shall shut down to sleep mode; HPD_SINK does not control DDC channel.
