TPMC863

TPMC863 4 Channel high-speed syn. Serial Interface

Four high speed serial data communication channels. The serial communication controller of the TEWS Technologies TPMC863 PMC module is implemented in FPGA logic, along with the bus master capable PCI interface, guaranteeing long term availability and having the option to implement additional functions in the future. Several interrupt sources can generate interrupts on INTA for each channel. Interrupts can be enabled and disabled separately. A 14.7456 MHz oscillator provides standard asynchronous baud rates. An additional 24 MHz oscillator is provided for other baud rates. A 10 MHz oscillator is used for the synchronous baud rate of 10 Mbit/s.

Each channel supports various serial communication protocols such as HDLC, asynchronous, isochronous, synchronous. Multiprotocol transceivers are used for the line interfaces. The physical interface can be selected by software individually for each channel as EIA-232, EIA-422, EIA-449, EIA-530, EIA-530A, V.35, V.36 or X.21.

The TPMC863 supports RxD+/-, TxD+/-, RxC+/-, TxC+/-, RTS+/-, CTS+/- and CD+/- lines for each channel. Additionally channel 3 provides DSR3+/- and DTR3+/- signals, both over front I/O only. The FPGA controller contains a receive and transmit FIFO of 512 long words (32 bit) per channel.

The TPMC863 provides front panel I/O via a HD-68 SCSI-3 type connector and P14 I/O.

A wide range of drivers is available: Linux, QNX, VxWorks and Windows. All drivers - except the Windows drivers - are supplied as C source code.
