    The LSI22915A has two 16-bit Low Voltage Differential (LVD) and Single-Ended (SE) Ultra160 SCSI channels that connect to the PCI local bus on your computer. The LSI22915A is tailored to systems that require on-board BIOS support. When you install the LSI22915A in your PCI system, you can connect up to 15 SCSI disk drives and other SCSI devices to each of its two SCSI channels.

  • Page 17: Lvdlink™ Technology Benefits

    ™ LVDlink Technology Benefits The LSI22915A supports LVD, a signaling technology that increases the reliability of SCSI data transfers over longer distances than those supported by SE SCSI. The low current output of LVD allows the I/O transceivers to be integrated directly onto the chip. LVDlink technology lowers the amplitude of noise reflections and allows higher transmission frequencies.

  • Page 33: Terminating The Scsi Bus

    The LSI22915A automatically enables its own termination when it is at the end of the bus. (In other words, the LSI22915A terminates itself if you connect only internal SCSI devices or only external SCSI devices.) LVD SCSI devices are usually terminated with external terminators, but sometimes termination is set with jumpers or with a switch on the device.
  • Page 34 The LSI22915A automatically controls SCSI bus termination for these three different bus configurations: • Section 2.2.6.1, “Internal SCSI Devices Only” • Section 2.2.6.2, “External SCSI Devices Only” • Section 2.2.6.3, “Internal and External SCSI Devices” 2.2.6.1 Internal SCSI Devices Only...
