SPI-200 Abaco Systems Quad IP Carrier for DSP-Link3 Processor Boards

The Abaco Systems / SBS / Greenspring SPI-200 Quad IP Carrier for DSP-Link3 Processor Boards is a four slot IndustryPack® carrier that uses a DSP-Link3 connection for communication with the host processor. It is a full size ISA card but all communication with the processor is done through the DSP-Link3 connector. It does not have any connections to the ISA bus except power and ground. The DSP-Link3 connection is made through a high density 64 pin ribbon cable. The SPI-200 adds a broad range of I/O and memory capabilities to DSP-Link3 processor systems and is appropriate for rugged industrial and commercial configurations.

Each IndustryPack slot may be individually configured for either 8 MHz or 32 MHz operation. The carrier supports four single-wide IPs, two double-wide or a combination. All accesses to the IndustryPacks use the upper 16 bits of the 32 bit DSP-Link3 data bus and use Ready-Controlled cycles. Each IndustryPack slot has a page register to allow the full 8 MB of memory space defined by the IndustryPack Module Specification. The page registers may be accessed by either Standard or Standard Fast ASTRB/ cycles.

The SPI-200 provides protected, filtered +5V, +12V, and -12V supplies to all the IndustryPack by means of passive "T" filters, capacitors and fuses. The three terminal filters provide excellent RF rejection of power supply conducted noise.
