The purpose of this article is to review these requirements and to show how a balanced LVD driver provides more system margin – and reliability -- for the system designer, system integrator, or VAR. Low Voltage Differential (LVD) signaling technology will be used in the next generation of parallel SCSI products. This is because the Ultra2 SCSI standard shifts the physical interface from a single-ended physical interface to an LVD physical interface. In an LVD physical interface, each signal has a dedicated return conductor as compared to a single-ended interface. An LVD driver generates this differential signaling where each SCSI signal has a plus signal (+) on one conductor and its exact complement minus signal (-) on the other conductor. LVD signaling is inherently less noisy than single-ended signaling and offers many I/O system benefits including greater cable distances, more device connectivity, and faster data transfer rates.
