Application Information

The TPMC863 is a standard single-width 32 bit PMC with

four high speed serial data communication channels.

The TPMC863 is the successor of the discontinued

TPMC862, providing similar functionality and full

connector and pin-out compatibility.

The serial communication controller 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.

Each channel has a receive and a transmit FIFO of 512

long words (32 bit) per channel for high data throughput.

Data transfer on the PCI bus is handled via TPMC863

initiated DMA cycles with minimum host/CPU intervention.

Several serial communication protocols are supported by

each channel, such as asynchronous, isochronous,

synchronous and HDLC mode.

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 also provides various interrupt sources,

generated on INTA. The interrupt sources can be enabled

or disabled individually.

Multiprotocol transceivers are used for the line interface.

The physical interface is selectable 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 following signals are provided by the TPMC863 for

each channel at the front and rear-I/O connectors:

Receive Data (RxD +/-), Transmit Data (TxD +/-), Receive

Clock (RxC +/-), Transmit Clock (TxC +/-), Ready-To-Send

(RTS +/-), Clear-To-Send (CTS +/-), Carrier-Detect

(CD +/-) and GND. Additionally serial channel 3 provides

Data-Set-Ready (DSR3 +/-) and Data-Terminal-Ready

(DTR3 +/-) at the front I/O connector.

The TPMC863 provides front panel I/O via an HD68

SCSI-3 type connector and rear I/O via P14.

Software Support (TDRV009-SW-xx) for different

operating systems is available.
