General Description
1-3
Does not require software
The SYM53C141 SCSI Bus Expander works with the LSI Logic extensive
SYM53C7xx and SYM53C8xx family of SCSI products. It also works with
other industry SCSI controllers, disk drives, and SCSI peripherals. Use
the SYM53C141 for those difficult SCSI subsystem designs.
Figure 1.1 illustrates the signal grouping of the SYM53C141 SCSI Bus
Expander device. A SCSI SE bus connects directly to the SCSI A-side.
The interface signals are SCSI bus compatible driver and receiver
signals with no internal termination. The SCSI B-side connects directly
to a SCSI SE bus or to a SCSI LVD bus. The interface signals utilize LVD
Link technology.
