This pin may be either connected to ground of left unconnected. This pin does not effet the
performance of the device.
8
Loss of Signal (LOS) Threshold. Connect a resistor from this pin to ground to set the input signal
level at which LOS outputs will be asserted. See Application Information section.
9
Inverted Loss of Signal Output. LOS is HIGH for input signals above the threshold programmed by
TH. See Detailed Description section.
10
Noninverted Loss of Signal Output. LOS is LOW for input signals above the threshold
programmed by TH. See Detailed Description section.
