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) PDN1 = PDN2 = VDD means receiver off
-
Fast start-up is triggered when the receiver is after power down controlled to power up
2) 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)
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) Receiver inputs RFIP and RFIM have both 600 kΩ biasing resistors towards VDD
