Application Information

The TXMC463 is a standard Switched Mezzanine Card (XMC) compatible module offering 4 channels of high performance asynchronous serial interface.

All modules offer front panel I/O with four RJ45 connectors. Four different standard modules are available: The TXMC463-10R and -15R provide 4 RS232 interfaces. The TXMC463-11R provides 4 RS422 interfaces. The TXMC463-12R provides 2 RS232 and 2 RS422 interfaces. The TXMC463-15R uses a non-standard RJ45 I/O pinout (as used on Motorola CPU boards).

Other configurations are available as factory build option on a per channel base.

Each RS232 channel supports TxD, RxD, CTS, RTS, DTR, CD, DSR/RI and GND. Each RS422 channel supports RxD+/-, TxD+/- and GND.

Each channel has 256 byte transmit and receive FIFOs to significantly reduce the overhead required to provide data to and get data from the transmitters and receivers. The FIFO trigger levels are programmable and the baud rate is individually programmable up to 1 Mbps for RS232 channels and 16 Mbps for RS422 channels. The UART offers readable FIFO levels.

All serial channels use ESD protected transceivers. ESD protection is up to ±15KV.

Software Support (TDRV002-SW-xx) for different operating systems is available.
