Introduction
1.2 Benefits of LVDlink
The SYM53C140 supports Low-Voltage Differential (LVD) technology for
SCSI, a signaling technology that increases the reliability of SCSI data
transfers over longer distances than those supported by single-ended
SCSI technology. The low current output of LVD allows the I/O
transceivers to be integrated directly onto the chip. LVD provides the
reliability of High-Voltage Differential (HVD) SCSI technology without the
added cost of external differential transceivers. LVD allows a longer SCSI
cable and more devices on the bus. LVD provides a long-term migration
path to even faster SCSI transfer rates without compromising signal
integrity, cable length, or connectivity.
For backward compatibility to existing single-ended devices, the
SYM53C140 features multimode LVDlink transceivers that can switch
between LVD and single-ended modes.
Integrated LVDlink Multimode transceivers
Supports single-ended, LVD, or HVD technology (HVD must
have external transceivers)
Allows greater device connectivity and longer cable length
LVDlink transceivers save the cost of external differential
transceivers
Supports a long-term performance migration path
