A = Analog, D = Digital, P = Power, G = Ground, I = Input, O = Output, NC = Not Connected
Notes:
1) External crystal compensation capacitor pin QOM is connected only in MAS6180A5 version. It is left
unconnected in MAS6180A1 and A2 versions which have internal compensation capacitor.
2) Pin 6 between QOM and QI must be connected to VSS to eliminate DIL 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)
-
the output is a current source/sink with |I
OUT
| > 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 (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 600 kΩ biasing resistors towards VDD
