CS48AU2B Data Sheet

The brand new CS48AU2B device is still based on the same

high-performance 32-bit fixed point Digital Signal Processor

core but instead is equipped with much less memory, tailoring

it for more cost-effective applications which feature Audyssey

Laboratories audio processing technologies. Target

applications are:

FEATURES

World’s first cost-effective, high-performance 32-bit DSP

that is solely dedicated to enable Audyssey Laboratories

audio processing technologies for today’s high-volume

consumer electronic products

Features: Audyssey Dynamic Volume^TM, Audyssey Dynamic

—

Digital Televisions

EQ^TM, Audyssey EQ^TM& Audyssey BassXT^TM/BassXT-TV^TM

—

iPod Docking Stations

Audyssey Dynamic Volume eliminates the need for

Automotive Head Units (OEM and Aftermarket)

constant volume adjustments

Automotive Outboard Amplifiers (OEM and Aftermarket)

Audyssey Dynamic EQ enables a reference playback

—

Blu-ray Disc Receivers

experience at any desired playback level

Soundbars / Sound Projectors

Audyssey EQ removes much of the distortion caused by

speaker enclosures and the typical room environment

producing greatly improved sound compared to similar

products without correction

The following Audyssey Laboratories algorithms are currently

supported on the CS48AU2B and more are in development:

Audyssey BassXT and BassXT-TV are specifically

calibrated to enhance the physical bass response of each

product model

While the individual Audyssey processing algorithms have

already been implemented on this DSP, the CS48AU2B is

programmed using the Cirrus proprietary DSP Composer

™

GUI development tool.

Configurable Serial Audio Inputs/Outputs

Processing chains combining both standard signal

processing blocks (Tone Control, Bass Management, etc.) in

combination with any combination of Audyssey Laboratories

technology algorithm blocks may be designed using a simple

drag-and-drop interface to create a custom signal flow

specific to your product model. The end result of this is a

software image that is down-loaded to the DSP via serial host

—

Maximum 32-bit @ 192 kHz

(Note: Audyssey Laboratories algorithms support 48 kHz,

44.1 kHz and 32 kHz)

—

Integrated 192 kHz capable S/PDIF transmitter

Integrated Clock Manager/PLL

—

Can operate from external crystal, external oscillator

(I C^®or SPI^TM) or via a serial master (self) boot.

Input Fs Auto Detection & Coefficient Loading

Host Control & Boot via Serial Interface

Support for loading of the various Audyssey Laboratories

algorithm coefficient files supplied by Audyssey Laboratories

is easily supported via DSP Composer, enabling the

OEM/ODM to quickly be able to generate the necessary files

for the system microcontroller which have been custom

tailored for each specific model based on the measurement

and analysis performed by Audyssey Laboratories.

Support for Master (Self) Boot via Serial EEPROM for

single Fs applications (i.e. 48 kHz only via ADC input)

Configurable GPIOs and External Interrupt Input

1.8V Core and a 3.3V I/O that is tolerant to 5V input

Low-power Mode
