Features
  • 80 Mbytes per second (max) input transfer rate via the front panel connector (RS422/485 differential I/O transceivers)
  • 200 Mbytes per second input transfer rate via the front panel connector (Pseudo ECL I/O transceivers)
  • 132 Mbytes per second PCI transfer rate in burst mode.
  • A single board can interface to a wide variety of external high-speed devices.
  • "Deep FIFO buffers" (up to 512 Kbytes) allow data bursts to be transferred over the PCI bus independent of transfers over the cable.
  • 32-Bit data transfers on the PCI bus
  • On-board cable controller, FIFOs, and DMA engine provide for continuous data transfer capability.
  • Data input/output clock rate up to 20 MHz (50 MHz max PECL)
  • Data input/output width of 32 bits
  • "Program-and-forget" DMA engine handles D32 transfers, also DMA Chaining · Interrupts available upon DMA-completion, FIFO status, cable status,

Description
  • The PCI-HPDI32A board is a fast and flexible bi-directional 32-bit digital I/O board that transmits and receives data up to 80 Mbytes (differential I/O) or up to 200 Mbytes (Pseudo ECL I/O) per second. The board is use-ful as a general-purpose DMA interface to a variety of external peripherals. The DMA engine is capable of transferring data to/from Host memory using D32 block transfers, while the FIFO memory (up to One Mbyte of total FIFO) provides continuous transmission of data without interrupting the DMA transfers or requiring intervention from the Host CPU.

    The board has 7 bi-directional programmable handshake lines and eight pre-configured software selectable interface protocols to allow easy interfacing to most digital I/ O peripherals. Available transceivers are RS485/422 and PECL. For TTL and LVDS transceiver versions, please see the PCI64-HPDI32ALT.
