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.
