Glossary

Adoption.: Refers to user adoption of Serial ATA, where Serial ATA is often seen in homes and businesses.
CRC.: 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.
Device.: 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.
EMI.: Acronym for electromagnetic interference.
FIS.: 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.
HBA.: Acronym for host bus adapter sometimes...
