issue with SCSI operations. TolerANT input signal filtering is a built-in
feature of the LSI53C1000 and all LSI Logic Fast SCSI, Ultra SCSI,
Ultra2 SCSI, and Ultra160 SCSI devices.
The benefits of TolerANT technology include increased noise immunity
when the signal transitions to HIGH, better performance due to balanced
duty cycles, and improved fast SCSI transfer rates. In addition, TolerANT
SCSI devices do not cause glitches on the SCSI bus at power-up or
power-down. This protects other devices on the bus from data corruption.
When used with the LVDlink transceivers, TolerANT technology provides
excellent signal quality and data reliability in real world cabling
environments. TolerANT technology is compatible with both the
Alternative One and Alternative Two termination schemes proposed by
the American National Standards Institute.
