Please consider that interface is at +1.8V_DSW electrical level; therefore, please evaluate well the typical scenario of application. If there isn t any explicit need of
interfacing directly at +1.8V_DSW level, for connection to standard serial ports commonly available (like those offered by common PCs, for example) it is mandatory
to include an RS-232 transceiver on the carrier board.
In the following schematic here is an example of UART interface on the carrier board, with a multiprotocol transceiver allowing to support RS485/RS-422/RS-232
serial interfaces.
