Glossary of Terms and Abbreviations
The glossary contains an alphabetical list of terms, phrases, and abbreviations used in this
book. Some of the terms and definitions included in the glossary are reprinted from IEEE
Std 754-1985, IEEE Standard for Binary Floating-Point Arithmetic, copyright ©1985 by

A
Asserted. Indicates active state of signal has been set. Refers to either inputs
or outputs.
B
BERC. Bit Error Rate Checking.
BERT. Bit Error Rate Testing.
BIST. Built-In Self-Test.
Bit alignment. Refers to the transition tracking loop recovering data bits
from the serial input stream.
Byte. Eight bits of uncoded data.
Byte alignment. Receiver identification of character boundaries through use
of Idle character recognition.
C
Character. An 8B/10B encoded byte of data.
D
Double data rate (DDR). The data is transferred on both the rising and
falling edge of the clock rather than on just the rising edge.
G
Gigabit. A unit of speed of data transfer. One gigabit indicates a data
throughput of 1 billion bits per second requiring a transfer rate of
1.25 billion symbols per second of 8B/10B encoded data.
Gigabaud. A unit of speed of symbol transfer. One gigabaud indicates a data
throughput of 800 million bits per second requiring a transfer rate of
1.0 billion symbols per second of 8B/10B encoded data.
