DIE size = 1.91 x 1.78 mm; PAD size = 100 x 100 µm except for VSS PAD size 104 x 112 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 the center of VDD pad

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.
