ELECTRICAL CHARACTERISTICS (continued)
RSSI/Carrier Detect
Connect 0.01 µF to Gnd from “RSSI” output pin to form the
carrier detect filter. “CD Out” is an open collector output
which requires an external 100 kΩ pull–up resistor to VCC.
The carrier detect threshold is programmable through the
MPU interface.
(RL = 100 kΩ, VCC = 2.6 V, TA = 25°C.)

Data Amp Comparator (see Figure 4)
Inverting hysteresis comparator. Open collector output
with internal 100 kΩ pull–up resistor. A band pass filter is
connected between the “Det Out” pin and the “DA In” pin with
component values as shown in the attached block diagram.
The “DA In” input signal is ac coupled.
(VCC = 2.6 V, TA = 25°C)
