NAME
FUNCTION
1
19
SQUELCH
Squelch Input. The squelch function disables the data outputs by forcing OUT- low and OUT+
high during a loss-of-signal condition. Connect to GND or leave unconnected to disable.
Connect to VCC to enable squelching.

20
VTH
Output of Internal Op Amp that Sets Loss-of-Signal Threshold Voltage (Figure 1). Connect a
resistor from VTH to INV and from INV to ground (minimum resistance 100k) to program the
desired threshold voltage.

1
INV
Inverting Input of Internal Op Amp that Sets Loss-of-Signal Threshold Voltage (Figure 1).
Connect a resistor from VTH to INV and from INV to ground (minimum resistance 100k) to
program the desired threshold voltage.
4
2
FILTER
Filter Output of Full-Wave Logarithmic Detectors (FWDs). The FWD outputs are summed
together at FILTER to generate the received-signal-strength indicator (RSSI). Connect a
capacitor from FILTER to VCC for proper operation.
5
3
RSSI
Received-Signal-Strength Indicator Output. The analog DC voltage at RSSI indicates the input
signal power. The RSSI output is reduced approximately 120mV when LOS+ is asserted.

IN-
Inverting Data Input

IN+
Noninverting Data Input

SUB
Substrate. Connect to ground.
9, 10
6, 7, 8
GND
Ground
11
9
CZP
Auto-Zero Capacitor Input. Connect a capacitor between CZP and CZN to determine the offset-
correction-loop bandwidth.
12
10
CZN
Auto-Zero Capacitor Input. Connect a capacitor between CZP and CZN to determine the offset-
correction-loop bandwidth.
13
11
VCCO
Output Buffer Supply Voltage. Connect to the same potential as VCC, but filter VCCO and VCC
separately.
14
12
OUT+
Noninverting PECL Data Output. Terminate with 50 to (VCC - 2V).
15
13
OUT-
Inverting PECL Data Output. Terminate with 50 to (VCC - 2V).
16
14
LOS-
Inverting Loss-of-Signal Output. LOS- is asserted low when input power drops below the LOS
threshold. This pin is PECL compatible and should be terminated with 50 to (VCC - 2V).
17
15
LOS+
Noninverting Loss-of-Signal Output. LOS+ is asserted high when input power drops below the
LOS threshold. This pin is PECL compatible and should be terminated with 50 to (VCC - 2V).
18
16
VCCO
MAX3964A/MAX3968: This pin can be left open or connected to the positive supply.

Exposed
Pad
Connect the exposed pad to board ground for optional electrical and thermal performance.
