DIE size = 1.47 x 1.46 mm; PAD size = 80 x 80 µm
Note: Because the substrate of the die is internally connected to VDD, the die has to be connected to VDD or left
floating. Please make sure that VDD is the first pad to be bonded. Pick-and-place and all component assembly
are recommended to be performed in ESD protected area.
Note: Coordinates are pad center points where origin has been located in bottom-left corner of the silicon die.

Notes:
1) 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)
2) 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
3) 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.
4) External crystal compensation capacitor pin QOM is connected only in MAS9190A5 and AF versions. It is left
unconnected in MAS9180A1 and AB..E versions which have internal compensation capacitor.
5) Differential input versions A1..A5 have 600 kΩ biasing MOSFET-transistors towards ground from both
receiver inputs RFIP and RFIM. Asymmetric input versions AB..AF have input pin RFIM unconnected.
