Notes:

1) Pin 4 between quartz crystal filter pins must be connected to VSS to eliminate package leadframe 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.

2) OUT = VSS when carrier amplitude at maximum; OUT = VDD when carrier amplitude is reduced

(modulated)

-

-

at power down the output is pulled to VSS (pull down switch)

3) AON = VSS means AGC off (hold current gain level); AON = VDD means AGC on (working)

-

Internal pull-up (to AGC on) with current < 1

µA which is switched off at power down

4) PDN = VSS means receiver on; PDN = VDD means receiver off

-

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.
