  • Page 15: Board Characteristics

    PCI is a high-speed standard local bus for interfacing a number of I/O components to the processor and memory subsystems in equipment ranging from PCs to servers. The PCI functionality for the LSIU80ALVD is contained within the LSI53C895A. The LSI53C895A connects directly to the PCI bus and generates signal timing and bus protocol in compliance with the PCI Specification Revision 2.1.

  • Page 16: The Scsi Interface

    The LSIU80ALVD supplies SCSI bus TERMPWR through a blocking diode and a self-resetting 1.5 A short circuit protection device. A 40 MHz oscillator is installed on the LSIU80ALVD to provide the clock frequency to the LSI53C895A that is necessary to support Ultra2 SCSI transfers of up to 80 Mbytes/s.

  • Page 17: Ultra2 Scsi Technology

    1.3.3 Ultra2 SCSI Technology The LSIU80ALVD fully supports Ultra2 SCSI. Ultra2 SCSI is an extension of the SCSI Parallel Interface 2 and 3 (SPI-2 and SPI-3) family of standards that expands the bandwidth of the SCSI bus, allowing faster synchronous data transfers.

  • Page 18: On-Board Led

    On-board LEDs are used to indicate the status of the SCSI bus. The SCSI Activity LED lights when the SCSI bus is transferring information. Using the LSIU80ALVD To utilize Ultra2 SCSI performance, the user must only have LVD devices on the bus. Do not mix any SE devices with LVD devices as the entire bus will drop to SE with maximum Ultra SCSI performance.
