PMC-5565PIORC Reflective Memory - interface allows data to be shared between up to 256 independent systems (nodes) at rates up to 174 Mbyte/s. Each Reflective Memory board may be configured with 64 MB or 128 MB of onboard SDRAM.The local SDRAM provides fast Read access times to stored data. Writes are stored in local SDRAM and broadcast over a high speed fiber-optic data path to other Reflective Memory nodes. The transfer of data between nodes is software transparent, so no I/O overhead is required. Transmit and Receive FIFOs buffer data during peak data rates to optimize the host computer and bus performance to maintain high data throughput.

PMC-5565PIORC is RoHS compliant. It has improved PIO read performance and firmware that can be upgraded in the field.

RoHS Compliant

Product Overview

  • High speed, easy to use fiber-optic network (2.12 Gbaud serially)
  • Data written to memory in one node is also written to memory in all nodes on the network
  • Up to 256 nodes
  • Connection with multimode fiber up to 300m, single mode fiber up to 10km
  • Dynamic packet size, 4 to 64 bytes of data
  • Transfer rate 43 Mbyte/s (4 byte packets) to 174 Mbyte/s (64 byte packets)
  • 64 Mbyte or 128 Mbyte SDRAM Reflective Memory
  • Two independent DMA channels
  • Any node on the network can generate an interrupt in any other node on the network or in all network nodes with a single command
  • Error detection
  • Redundant transfer mode for extra error suppression
  • No processor overhead
  • No processor involvement in the operation of the network
  • PCI 64-bit 66 MHz transfers, 3.3 or 5V, single width mezzanine interface
