Power Supply Ground

A = Analog, D = Digital, P = Power, G = Ground, I = Input, O = Output, NC = Not Connected

Notes:

1) QOM pin is electrically unconnected in MAS6180C1 version

2) Pin 4 between QOM and QI must be connected to VSS to eliminate TSSOP package lead frame parasitic

capacitances disturbing the crystal filter performance. All other NC (Not Connected) type pins are also

recommended to be connected to VSS to minimize noise coupling.

3) 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)

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

-

Internal pull-up with current < 1 µA which is switched off at power down

5) 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.

6) Receiver inputs RFIP and RFIM have both 1.4 MΩ biasing resistors towards VDD
