Application Information
The TCP863 is a standard 3U 32 bit CompactPCI module
with four high speed serial data communication channels.
The TCP863 is the successor of the discontinued
TCP862, providing similar functionality and full connector
and pin-out compatibility.
The TCP863-10R provides front panel I/O via HD68 SCSI3 type connector and TCP863-20R additionally provides
rear I/O via J2.
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 provides dedicated receive and transmit
FIFOs for high data throughput.
Data transfer on the PCI bus is handled via TCP863
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 TCP863 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.
Driver support (TDRV009-SW-xx) for different operating
systems is available.
