NOTE: Input amplitude that is <550mV and >325mV will not reliably cause the LLA output to go HIGH. Input amplitude that is <325mV will
always flag the LLA output HIGH.
NOTE: Logic High, logic Low, and a differential short on the inputs will cause the LLA output to go HIGH. This feature is only available when
both differential inputs are being used, and their respective frequencies are within ±50% of one another (i.e.: CLK0 is 100MHz, CLK1 must be
within 50MHz to 150MHz).
