PIN DESCRIPTION
Notes:
1) Pin 5 between quartz crystal filter pins must be connected to VSS to eliminate DIL package leadframe
2) OUT = VSS when carrier amplitude at maximum; OUT = VDD when carrier amplitude is reduced
3) AON = VSS means AGC off (hold current gain level); AON = VDD means AGC on (working)
4) PDN = VSS means receiver on; PDN = VDD means receiver off
parasitic capacitances disturbing the crystal filter performance. All other NC (Not Connected) pins are also
recommended to be connected to VSS to minimize noise coupling.

the output is a current source/sink with |I
at power down the output is pulled to VSS (pull down switch)
Internal pull-up with current < 1 µA which is switched off at power down
Fast start-up is triggered when the receiver is after power down (PDN=VDD) controlled to power up
(PDN=VSS) i.e. at the falling edge of PDN signal.
