Glossary
Single-Ended
Configuration
An electrical signal configuration that uses a single line for each signal,
referenced to a ground path common to the other signal lines. The
advantage of a single-ended configuration is that it uses half the pins,
chips, and board area that differential/low-voltage differential
configurations require. The main disadvantage of single-ended
configurations is that they are vulnerable to common mode noise. Also,
cable lengths are limited.
Synchronous
Transmission
Transmission in which the sending and receiving devices operate
continuously at the same frequency and are held in a desired phase
relationship by correction devices. For buses, synchronous transmission
is a timing protocol that uses a master clock and has a clock period.
Target
A SCSI device that performs an operation requested by an initiator.
Termination
The electrical connection at each end of the SCSI bus, composed of a set
of resistors.
Ultra3 SCSI
A standard for SCSI data transfers. It allows a transfer rate of up to
160 Mbytes/s over a 16-bit SCSI bus. STA (SCSI Trade Association)
supports using the terms “Ultra3 SCSI” over the term “Fast-80.”
