The amount of 1 kHz signal present on the output of the grounded AC-coupled line input channel with 1
kHz, 0 dB, signal present on the other line input channel. Units are in dB.
Refers to a consumer equipment compatible, voltage driven interface. The term implies a low driver
impedance and a minimum 10
A-D: Analog in, through the ADCs, onto the serial link.
D-A: Serial interface inputs through the DACs to the analog output.
A-A: Analog in to Analog out (analog mixer).
Refers to the PC 99 System Design Guide published by the Microsoft
Phase Lock Loop. Circuitry for generating a desired clock from an external clock source.
The number of bits in the output words to the DACs, and in the input words to the ADCs.
SNR, similar to DR, is the ratio of an arbitrary sinusoidal input signal to the RMS sum of the noise floor,
in the presence of a signal. It is measured over a 20 Hz to 20 kHz bandwidth with units in dB.
Sony/Phillips Digital Interface. This interface was established as a means of digitally interconnecting
consumer audio equipment. The documentation for S/PDIF has been superseded by the IEC-958
consumer digital interface document.
Sample Rate Converter. Converts data derived at one sample rate to a differing sample rate. The
CS4299 operates at a fixed sample frequency of 48 kHz. The internal sample rate converters are used
to convert digital audio streams playing back at other frequencies to 48 kHz.
THD+N is the ratio of the RMS sum of all non-fundamental frequency components, divided by the RMS
full-scale signal level. It is tested using a -3 dB FS input signal and is measured over a 20 Hz to 20 kHz
bandwidth with units in dB FS.
