Description
RSSI is the receive signal strength indicator. This
pin must be filtered through a capacitor to ground.
The capacitance value range should be 0.01 to
0.1 µF. This is also the input to the Carrier Detect
comparator. An external R to ground shifts the
RSSI voltage.

Mix2 In
Mix2 In is the second mixer input. Signals are to be
ac–coupled to this pin, which is biased internally to
VCC RF. The input impedance is
2.8 kΩ at 455 kHz. The input impedance can be
reduced by connecting an external resistor to
VCC RF.
