The PCI functionality for the SYM8953U is contained within the Symbios SYM53C895A PCI to Ultra2 Controller with LVD Link Universal Transceivers. The SYM53C895A connects directly to the PCI bus and generates signal timing and bus protocol in compliance with the PCI Specification

Ultra2 SCSI is an extension of the SCSI Parallel Interface 2 and 3 (SPI-2 and SPI-3) family of standards. SCSI2 expands the bandwidth of the SCSI bus, allowing faster synchronous data transfers. For the internal bus, special impedance SCSI ribbon cables are specified for operation with Ultra and Ultra2 SCSI devices. You must consider the total length of the bus cables and the

LVD provides the reliability of HVD SCSI without the added cost of external differential transceivers. Ultra2 SCSI with LVD allows a longer SCSI cable and more devices on the bus, using the same cables defined in the SCSI-3 parallel Interface (SPI-2) standard for Ultra SCSI. Important: To utilize Ultra2 SCSI performance, you must only have LVD devices on the bus. Do not mix any SE devices with LVD
