first!

DIE size = 1.07 mm x 1.37 mm; PAD size = 80 µm x 80 µm

Note: Because the substrate of the die is internally connected to VSS, the die has to be connected to VSS or left

floating. Please make sure that VSS 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) 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) 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 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.

5) Receiver inputs RFIP and RFIM have both 600 kΩ biasing resistors towards VDD
