Refers to the Audio Codec ‘97 Component Specification Ver 2.1 published by Intel
Corporation [].
Refers to the control chip which interfaces to the Codec’s AC-link. This has been also called
DC ’97 for Digital Controller ‘97 [].
Refers to the 64-field register map defined in the AC ’97 Specification.
Refers to a single Analog-to-Digital converter in the Codec. “ADCs” refers to the stereo pair of
Analog-to-Digital converters.
A single Digital-to-Analog converter in the Codec “DACs” refers to the stereo pair of Digital-
to-Analog converters.
Sample Rate converter. Converts data derived at one sample rate to a differing sample rate.
Refers to the chip containing the ADCs, DACs, and analog mixer. In this data sheet, the Codec
is the CS4297A9.
Fast Fourier Transform.
The number of bits in the output words to the DACs, and in the input words to the ADCs.
The worst case deviation from the ideal code width. Units in LSB.
dB FS is defined as dB relative to full-scale. The “A” indicates an A weighting filter was used.
