Supply Ground
Noninverted Input Signal
Inverted Input Signal
Supply Ground
This pin may be either connected to ground of left
unconnected. This pin does not effet the performance of the
device.
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.
Inverted Loss of Signal Output. LOS is HIGH for input
signals above the threshold programmed by TH. See
Detailed Description
section.
Noninverted Loss of Signal Output. LOS is LOW for input
signals above the threshold programmed by TH. See
Detailed Description
section.

Squelch Input. Squelch is disabled if this pin is
unconnected or set LOW. When SQUELCH is HIGH,
OUT+ and OUT- are forced to static levels. See
