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 |I
OUT
| > 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) PDN1 = VDD and PDN2 = VDD means receiver off
-
Fast start-up is triggered when the receiver is after power down controlled to power up
4) Receiver inputs RFIP and RFIM have both 600 kΩ biasing MOSFET-transistors towards ground
