ADAU1442/ADAU1445/ADAU1446

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.

be modified at any time via control registers, allows for maximum

system flexibility.

The ADAU1442, ADAU1445, and ADAU1446 differ only in

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 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

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.
