Industrial RF transceiver

[1]

Pin TEST must be connected to ground in the application.

[2]

The exposed die pad area must be connected to ground.

[3]

VDD_DIGL is the internal supply of the digital part and shall only be externally connected to a blocking

capacitor 15 nF (nominal).

[4]

VDD_DIGL must neither be pulled to high voltages nor to GND

[5]

Do not use VDD_DIGL to supply external devices

[6]

All GND_RF are connected internally

[7]

TXOUT is not to be supplied externally except for an inductor connected to VREGPA

[8]

RST_N shall be connected only with a 4.7 k

Ω resistor in series.

[9]

MSDA features an on-chip pull-up resistor to VDD_IO and may be left open or terminated to VDD_IO, as

desired.

[10] MSCL is an output and shall be unconnected in the application.
