1.5Benefits of LVDlink Technology
To support greater device connectivity and a longer SCSI cable, the LSIU160 features LVDlink technology, the LSI Logic implementation of Universal LVD SCSI. LVDlink transceivers provide the inherent reliability of differential SCSI, and a
The LVDlink transceivers reduce the power needed to drive the SCSI bus, so that the I/O drivers can be integrated directly into the chip. LVDlink technology lowers the amplitude of noise reflections and allows higher transmission frequencies.
The LVDlink transceivers operate in LVD and SE modes. They also allow the chip to detect a High Voltage Differential (HVD) signal when the chip is mistakenly connected to external HVD transceivers. When connected, the LSI53C1010 automatically detects the signal type, based on the voltage detected. It automatically switches to the SE or LVD mode, as appropriate.
Important: All bus devices must be LVD or SE. If a HVD device is
pcdetected, the board puts the SCSI bus in the high impedance state and shuts down.
1.6Benefits of TolerANT® Technology
The LSI53C1010 features TolerANT technology, which includes active negation on the SCSI drivers and input signal filtering on the SCSI receivers. Active negation causes the SCSI Request, Acknowledge, Data, and Parity signals to be actively driven HIGH rather than passively pulled up by terminators.
TolerANT receiver technology improves data integrity in unreliable cabling environments where other devices would be subject to data corruption. TolerANT receivers filter the SCSI bus signals to eliminate unwanted transitions, without the long signal delay associated with
