Voltage input to RSSI A/D converter. Full scale is 0
to 1.6 V.
Input to the Rx Audio Path. Input impedance is
600 k . Input signal must be capacitor coupled
Input for the digital data from the RF Receiver
section. Input impedance is 250 k . Hysteresis is
internally provided. Input signal level must be
between 50 and 700 mVpp.
Ground pin for the audio section. A direct
connection to a ground plan is strongly
recommended.
Buffered output of the 2nd LO. This high frequency
output is a current, requiring an external pullup
resistor.
Supply pin for the LO2 section. Allowable range is
2.7 to 5.5 V and must be within 0.5 V of all other
V CC pins. Good bypassing is required and isolation
with a 10
resistor is recommended.
