TTL output Limiting Amplifier
Pin Description
Pin No.
Name
Function
Auto-zero capacitor pin. A capacitor connected between this pin and AZ2 sets the
time constant of the offset correction loop. The offset correction is disabled when
the AZ1 and AZ2 pins are shorted together.

GNDA
INP
Analog Supply Ground. Must be at same potential as GNDE pin.
Positive data input
Negative data input
INN
Analog Supply Voltage. Must be at the same potential as the VCCE pin.
VCCA
CF
Level-detect filter capacitor pin. Connect a capacitor between this pin and VCCA.
The squelch function is disabled when JAM is connected to ground. The automatic
squelch function is enabled when JAM is connected to the LOSP.

JAM
Positive Loss-of-Signal output, CMOS level, compatible with PECL and TTL. LOSP is
low when the level of the input signal is above the preset threshold set by the VSET
input. LOSP is high when the signal level drops below the threshold. Normally
connected to JAM pin to enable automatic squelch function to operate.
Negative Loss-of-signal output, CMOS level, compatible with PECL and TTL. LOSN is
high when the level of the input signal is above the preset threshold set by the VSET
input. LOSN is low when the signal level drops below the threshold. Indicates Input
signal level status.

5V to 3V conversion output pin.No connection or can connect a capacitor
between this pin and GND.

Loss-of-Signal Threshold Pin. Resistor (RSET) to ground sets the LOS threshold. This
pin can be left open if the LOS detect function is not required and JAM is connected
to ground, otherwise connect VSET to ground.
