TCP863

4 Channel High Speed Synch/Asynch Serial Interface

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 SCSI-

3 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.
