Squelch Input. The squelch function is disabled when SQUELCH is not connected or set to TTL low
level. When SQUELCH is set to TTL high level and LOS is asserted, the data outputs (OUT+, OUT-)
are forced to static levels.
Noninverted Loss-of-Signal Output. LOS is asserted TTL high when the signal drops below the assert
threshold set by the TH input. The MAX3272 does not have ESD protection on this pin. The
MAX3272A has ESD protection on this pin.
Inverted Loss-of-Signal Output. LOS is asserted TTL low when the signal drops below the assert
threshold set by the TH input. The MAX3272 does not have ESD protection on this pin. The
MAX3272A has ESD protection on this pin.
Output Current Level. When this pin is not connected, the CML output current is approximately
16mA. When this pin is connected to ground, the output current increases to about 20mA.
Inverted Data Output
Noninverted Data Output
Output Polarity Control Input. Connect to GND for an inversion of polarity through the limiting
amplifier and connect to V

for normal operation.
Offset-Correction-Loop Capacitor Connection. A capacitor connected between this pin and CAZ1
extends the time constant of the offset correction loop. Typical value of C
AZ
is 0.1μF.
Offset-Correction-Loop Capacitor Connection. A capacitor connected between this pin and CAZ2
extends the time constant of the offset correction loop. Typical value of C
