Application Information

The TMPE863 is a standard full PCI Express Mini Card,

providing three high speed serial data communication

channels.

The serial communication controller is implemented in

FPGA logic along with the bus master capable PCIe

interface, guaranteeing long term availability and having

the option to implement additional functions in the future.

Data transfer to and from host memory is handled via

TMPE863 initiated DMA cycles for minimum host/CPU

intervention.

Each channel has a receive and transmit FIFO of 512 long

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

Several serial communication protocols are supported for

each channel, such as asynchronous (with oversampling),

isochronous, synchronous and HDLC mode.

Available signal encodings for synchronous data

communication are NRZ, NRZI, FM0, FM1 and

Manchester.

Available clock sources are 14.7456 MHz for standard

asynchronous baud rates, 10 MHz for the 10 Mbit/s

synchronous data rate and 24 MHz for other baud or data

rates.

Each channel provides various interrupt sources which

can be enabled or disabled individually.

The Differential I/O lines for EIA-422, EIA-485 Full-Duplex

are terminated with 120 Ω on-board.

The I/O signals are accessible through a 30 pin Pico-

Clasp latching connector. For Modules with Pico-Clasp

Connector, the TA309 Cable Kit is available.

The TMPE863 provides a basic heatsink to facilitate

thermal management. The heatsink can be used to install

additional cooling solutions like passive or active heatsinks

or to provide a thermal connection to an enclosure
