Description
Offset Correction Loop Capacitor. Place capacitor between
this pin and CZ2 to alter time constant of offset correction
loop. See Detailed Description section.
Offset Correction Loop Capacitor. Place capacitor between
this pin and CZ1 to alter time constant of offset correction
loop. See Detailed Description section.

Supply Ground
Output Current Level. This pin may either be connected to
ground or left unconnected. Connecting to ground causes
output current to be 20mA. The output is 16mA when left
unconnected. See Detailed Description section.
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.
