PCI GP-SSD

The PCI GP-SSD has been discontinued and is no longer supported; the information below is for reference only. For comparable products, see EDTs FPGA I/O products.

Features

• Serial rates up to 60 Mbits/sec (4 channel), 4 Mbits/sec (16 channel)
• Independent clock per channel
• Standard RS-422 or EIA-644 (LVDS), driver/receivers, or optionally RS-485 (please specify when ordering)
• Compatible with PCI platforms running Linux or Windows
• Single PCI Local Bus slot

Applications

• Monitoring serial data communications
• Telecom receiver

Description

The PCI GP-SSD is a family of synchronous serial interfaces. It can be ordered with RS-422, or EIA-644 (LVDS) drivers and receivers and preconfigured for 4 or 16 channels (4 channels is faster), or converted from one to the other in the field through a firmware download.

Two 4-channel modes are provided. In SSD4 mode, there are 1, 2 or 4 data bits plus 1 clock per channel, input only. In SSD4IO mode, there is 1 data bit plus 1 clock per channel, each channel independently selected as input or output.

When configured for 16 channels, there is 1 clock and 1 data bit per channel. In 16 channel mode, channels are programmed for either input or output in groups of four as follows: 0-3, 4-7, 8-11, and 12-15. The data is sampled on the rising edge of the clock and stored in the host computer memory by the PCI GP-SSD DMA. Data from each channel is stored in a different region of host memory.

Software

Device drivers for Linux and Windows are included with the PCI GP-SSD. The drivers provide access to the PCI through standard and asynchronous read and write system calls. A DMA ring buffer management library is provided for high speed continuous transfers. Example and utility programs written in the C language are also provided.

Cables

Custom cable assemblies suited to your application can be provided. click here for a list of standard EDT cable assemblies.

Options

When ordering, specify either 4- or 16-channel configuration, as well as signal level: RS422, EIA-644 (LVDS), or RS485. For ECL, order the PCI GP-ECL.
