7.6.1
UART3 Routing (RN47)
RN47 is used to route the signals of UART3 serial interface through the RS-232
transceiver or around the RS-232 transceiver when not populated. When RN47 is not
populated RXD3_TTL,TXD3_TTL,RTS3_TTL and CTS3_TTL are routed through the RS-
232 transceiver U21 and come out as x_RXD3_RS232, x_TXD3_RS232,
x_RTS3_RS232 and x_CTS3_RS232 at the phyCORE-connector pins X1 pin 22D, X1
pin 23D, X1 pin 25D, X1 pin 26D. If U21 does not populate the module, RN47 is
populated to route the TTL level signals to these same pins.
The standard phyCORE-i.MX31 module will have U21 populated, thereby routing the RS-
232 level signals to the phyCORE-connector. Be sure the phyCORE-i.MX31 configuration
you are working with before interfacing these signals outside of the module as incorrect
voltage levels will likely cause damage to on-board and off-board components.
The following configurations are possible:
