    • Section 1.3, “Interface Descriptions,” page 1-3 General Description The LSI Logic LSIU40SE provides a SCSI-3, Ultra SCSI interface to PCI computer systems. Installing this adapter in your PCI system allows connection of SCSI devices over a SCSI bus. The dual channel LSIU40SE is a 16-bit, Single-Ended (SE), SCSI solution for your computer, using only one PCI slot.

    LSI53C876. The LSI53C876 connects directly to the two SCSI buses and generates timing and protocol in compliance with the SCSI standard. The SCSI interfaces on the LSIU40SE operate as 16-bit, synchronous or asynchronous, SE bus, and support Ultra SCSI protocols and 16-bit arbitration.

  • Page 16: Ultra Scsi

    Separate switches for each channel allow user override of termination. A 40 MHz oscillator is installed on the LSIU40SE to provide the clock frequency to the LSI53C876 that is necessary to support Wide Ultra SCSI transfers of up to 40 Mbytes/s.
