1-6 Describing the LSI20160

Important: All bus devices must be LVD or SE. If a High Voltage
Differential (HVD) device is detected, the board puts the
SCSI bus in the high impedance state and shuts down.
1.6 TolerANT

Technology Benefits
The LSI20160 features TolerANT technology, which includes active
negation on the SCSI drivers and input signal filtering on the SCSI
receivers. The benefits of TolerANT technology include increased
immunity to noise when the signal is going 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, so other devices on the bus are also
protected from data corruption.
When it is used with the LVDlink transceivers, TolerANT technology
provides excellent signal quality and data reliability in real world cabling
environments. TolerANT input signal filtering is a built-in feature of the
LSI53C1000 device as well as all LSI Logic SCSI devices.
