Synchronous serial interface for PCI

The PCI GP-SSE is a legacy product, with limited availablity to existing customers only. Please see the SSE Mezzanine which has superseded this product.

  • 2 channels (one in/out, one in only)
  • 1 data bit per channel
  • ECL compatible driver/receivers
  • Transfer rates up to 400 megabits per second per channel
  • Implements a high-speed DMA channel between an external device and PCI computer
  • Customized by a RAM-based programmable gate array
  • Single short PCI bus slot
  • Low cost

The PCI GP-SSE board samples the data on the rising edge of the clock and stores it in host memory by the PCI GP-SSE DMA. It provides a simple, flexible low cost solution for telecom, datacom, and monitoring applications.

Two 9-pin D-connectors are provided, one for each channel. Each channel accepts a differential data signal (two wires) and a differential clock (two more wires) at standard ECL signal levels. All incoming signals are terminated through 50 ohms to -2 volts.

  • Telecom receiver
  • Monitoring serial data communications
  • Ground station support

Device drivers for Windowstm and Linux are included with the PCI GP-SSE, contact us about other operating systems.The driver provides access to the PCI GP-SSE through standard and asynchronous read and write system calls. A DMA ring buffer management library is provided for high speed continuous transfers.


Custom cables suited to your application can be provided.


EDT provides several levels of customer support, from phone consultation to custom design of hardware and software, at hourly rates.
