From Serial ATA Storage Architecture and Applications


Refers to user adoption of Serial ATA, where Serial ATA is often seen in homes and businesses.
Acronym for cyclic redundancy check. Used to verify the integrity of a transmission in a way similar to a checksum.
Command FIS.
A frame information structure that carries an ATA command (not a data payload) see also FIS and Data FIS.
Common Mode Voltage.
The voltage that is common to both sides of a differential circuit pair. If the line is perfectly balanced, the common mode voltage is cancelled.
Data Dependent Jitter.
Transmission of clock pattern to non-clock pattern, including inter-symbol interference.
Data FIS.
A frame information structure that carries a payload of data, not an ATA command. See also FIS and Command FIS.
Deterministic Jitter.
Systematic jitter that is not characterized by
Gaussian distribution probability.
Deterministic jitter includes duty cycle distortion jitter, sinusoidal jitter, data dependent jitter and uncorreleated jitter.
A computer peripheral, such as a hard disk drive. For this book, device almost always means a hard disk drive with a Serial ATA interface.
Acronym for electromagnetic interference.
Acronym for frame information structure. See also Data FIS and Command FIS.
Gbps or Gb/s.
Abbreviation of gigabits per second.
Gen 1 Speed.
1.5 gigabits per second, defined in the Serial ATA 1.0 specification.
Gen 2 Speed.
3.0 gigabits per second is targeted, but not guaranteed. This book pre-dates the Serial ATA specification that defines the Gen 2 signal timings.
Acronym for host bus adapter sometimes...

Products & Services
RAID Products
RAID products include component within a RAID system, such as RAID controllers and RAID disk arrays. RAID is an acronym for redundant array of independent (or inexpensive) disks.
RAID Disk Arrays
RAID disk arrays are collections of storage disks with integrated controllers to manage the storage of data.
Fiber Optic Transponders
Fiber optic transponders are devices that receive, amplify, and retransmit optical signals on different wavelength channels.
Network Clock Sources
Network clock sources are timing devices that use a signal from an atomic clock or other external reference source to set and maintain a central time for all of the elements in a network.
LAN Chips
LAN chips provide wireless local area network (LAN) connectivity in a system-on-chip platform.
