DESCRIPTION
The ST7597 is an analog component of a 2-chip
audio solution (which is not described in this speci-
fication). The two fixed 48kHz DAC’s support a
stereo PCM output channel which contains a mix
generated in the ST7597 controller of all software
sources, including the internal synthesizer and
any other digital sources. PCM out is mixed with
analog sources, processed with optional Stereo
Enhancement and tone controls, and sent to inde-
pendently controlled LINE_OUT. For speaker-
phone telephony, the MONO_OUT delivers either
mic only or a mono mix sources to the telephony
subsystem.
The ADC path support 2 channel of fixed 48kHz
input. The standard stereo PCM in channel sup-
ports record of any mono or stereo source, or a mix
of sources.
