TAMC863 4 Channel High Speed Synch/Asynch Serial Interface

Application Information

The TAMC863 is a standard single Mid-Size/Full-Size

AMC.1 compliant module with four high speed serial data

communication channels.

The serial communication controller is implemented in

FPGA logic, along with a bus master capable PCI

interface, guaranteeing long term availability with the

option to implement additional functions in the future. The

FPGA is connected to the PCI Express interface via a PCI

Express to PCI bridge.

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 TAMC863

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 TAMC863 for

each channel at the front I/O connector: Receive Data

Data-Set-Ready (DSR3 +/-)

and Data-Terminal-Ready

(DTR3 +/-).
