Power Supply Ground  
G
A = Analog, D = Digital, P = Power, G = Ground, I = Input, O = Output, NC = Not Connected  
Notes:  
1) Pin 4 between QOM and QI must be connected to IC’s filtered VDD (pin 1) to eliminate TSSOP package  
lead frame parasitic capacitances disturbing the crystal filter performance and minimizing noise coupling. All  
other NC (Not Connected) type pins are recommended to be connected to VSS.  
2) PDN1 = VDD and PDN2 = VDD means receiver off  
Fast start-up is triggered when the receiver is after power down controlled to power on  
-
3) OUT = VSS when carrier amplitude at maximum; OUT = VDD when carrier amplitude is reduced  
(modulated)  
-
The output is a current source/sink with |IOUT| > 5 µA  
At power down the output is pulled to VSS (pull down switch)  
-
4) AON = VSS means AGC off (hold current gain level); AON = VDD means AGC on (normal operation)  
-
Unused AON pad can be left unconnected due to internal pull-up with current < 1 µA. Pull up current is  
switched off at power down.  
5) Receiver inputs RFIP and RFIM have both 1.4 Mbiasing resistors towards VDD
