TEWS Technologies Extends mPCIe Module Family Into Communications with FPGA-Based 3 Channel High Speed Synch/Asynch Serial Interface

TEWS extends its tradition of delivering high-density I/O solutions with the introduction of a synchronous/asynchronous standard full PCI Express Mini Card module with three high speed serial data communication channels. The TMPE863 is designed for data communications, LAN/WAN networking, traffic control, simulation, telecommunications, and COTS applications.

To minimize obsolescence issues, 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.

To support many possible applications, 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 available 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. The TA309 Cable Kit is available to support this connector.

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.

Software drivers for VxWorks, Linux, Windows, QNX and Integrity are available.  To support long term programs, the TEWS´ modules have a 5-year warranty.
