Balanced LVD SCSI Drivers and Receivers (PDF)
A White Paper prepared by Ken Stuart and Kelly Bryant of Symbios, for the SCSI Trade Association

The requirements for LVD drivers and receivers are defined in Annex A of the SCSI Parallel
Interconnect-2 (SPI-2) specification and is available at:  
ftp://www.symbios.com/pub/standards/io/x3t10/drafts/spi2.

 
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.
