Pin Description

NAME
FUNCTION
1
INV
Inverting Input of Internal Op Amp that Sets Power-Detect Threshold Voltage (Figure 1). Connect a
resistor from V
TH
to INV (R2), and from INV to ground (R1 = 100k
), to program the desired threshold
voltage.
2
FILTER
Filter Output of Logarithmic Full-Wave Detectors (FWDs). The FWD outputs are summed together at
FILTER to generate the RSSI output. Connect a capacitor from FILTER to V
CC
for proper operation.
3
RSSI
Received-Signal-Strength Indicator Output. The voltage at RSSI indicates the input-signal power. The
RSSI output is reduced approximately 120mV when LOS is asserted.

SD
Signal Detect, PECL Output. The SD output is high when input power is above the power-detect
threshold, and low when input power is below the power-detect threshold. This pin is PECL-
compatible and should be terminated with 50
to (V
CC
- 2V) or equivalent.
15
LOS
Loss-of-Signal Output, TTL Open Collector (with ESD Protection). The LOS output is high when input
power is below the power-detect threshold, and low when input power is above the power-detect
threshold.
16
LOS
Inverted Loss-of-Signal Output, TTL Open Collector (with ESD Protection). The
LOS
output is low
when input power is below the power-detect threshold, and high when input power is above the
power-detect threshold.
