GENERAL DESCRIPTION
The ADAU1442/ADAU1445/ADAU1446 are enhanced audio
processors that allow full flexibility in routing all input and
output signals. The SigmaDSP core features full 28-bit processing
(56-bit in double-precision mode), synchronous parameter
loading for ensuring filter stability, and 100% code efficiency
with the SigmaStudio tools. This DSP allows system designers
to compensate for the real-world limitations of speakers, amplifiers,
and listening environments, resulting in a dramatic improvement
of the perceived audio quality through speaker equalization,
multiband compression, limiting, and third-party branded
algorithms.
The flexible audio routing matrix (FARM) allows the user to
multiplex inputs from multiple sources running at various
sample rates to or from the SigmaDSP core. This drastically
reduces the complexity of signal routing and clocking issues in
the audio system. FARM includes up to eight stereo asynchronous
sample rate converters (depending on the device model), Sony/
Philips Digital Interconnect Format (S/PDIF) input and output,
and serial (I2S) and time division multiplexing (TDM) I/Os. Any of
these inputs can be routed to the SigmaDSP core or to any of the
asynchronous sample rate converters (ASRCs). Similarly, any one
of the output signals can be taken from the SigmaDSP core or
from any of the ASRC outputs. This routing scheme, which can
be modified at any time via control registers, allows for maximum
system flexibility.
ASRC functionality and packaging. The ADAU1442/ADAU1445
contain 16 channels of ASRCs and are packaged in TQFP packages,
whereas the ADAU1446 contains no ASRCs and is packaged in
an LQFP. The ADAU1442 can handle nine clock domains, the
ADAU1445 can handle three clock domains, and the ADAU1446
can handle one clock domain.
The ADAU1442/ADAU1445/ADAU1446 can be controlled in
one of two operational modes: the settings of the chip can be
loaded and dynamically updated through the SPI/I2C port, or
the DSP can self-boot from an external EEPROM in a system
with no microcontroller. There is also a bank of multipurpose
(MP) pins that can be used as general-purpose digital I/Os or
as inputs to the 4-channel auxiliary control ADC.
The ADAU1442/ADAU1445/ADAU1446 are supported by the
SigmaStudio graphical development environment. This software
includes audio processing blocks such as FIR and IIR filters,
dynamics processors, mixers, low level DSP functions, and
third-party algorithms for fast development of custom signal flows.
