CS47048 Data Sheet

FEATURES

The CS47048 family is a new generation of audio system-on-a-

chip (ASOC) processors targeted at high fidelity, cost sensitive

designs. Derived from the highly successful CS48500 32-bit

fixed point audio enhancement processor family, the CS47048

further simplifies system design and reduces total system cost

by integrating the S/PDIF Rx, S/PDIF Tx, analog inputs, analog

outputs, and SRCs to simplify system design. For example, a

hardware SRC can down-sample a 192kHz S/PDIF stream to a

lower Fs to reduce memory and MIPS requirements for

processing. This integration effectively reduces the chip count

from 3 to 1 which allows smaller, less expensive board designs.

Cost-effective, High-performance 32-bit DSP

—

300,000,000 MAC/S (multiply accumulates per second)

Dual MAC cycles per clock

72-bit accumulators are the most accurate in the industry

32K x 32-bit SRAM with three 2K blocks assignable to either

Y data or program memory.

Integrated DAC & ADC Functionality

—

8 Channels of DAC output: 108dB DR, 98dB THD+N

4 Channels of ADC input: 105dB DR, 98dB THD+N

Integrated 5:1 analog mux feeds one stereo ADC

Target applications are:

— Automotive Head Units & Outboard Amplifiers

— Automotive Processors & Automotive Integration Hubs

— Digital TV

Configurable Serial Audio Inputs/Outputs

—

Integrated 192 kHz S/PDIF Rx

— MP3 Docking Stations

— AVR and DVD RX

— DSP Controlled Speakers (e.g. Subwoofers, Sound

Bars)

Integrated 192 kHz S/PDIF Tx

Supports 32-bit Serial Data @ 192 kHz

Supports 32-bit audio sample I/O between DSP chips

TDM I/O modes (Up to 8 channels per line)

The CS47048 is programmed using the simple yet powerful

Supports Different Fs Sample Rates

Cirrus proprietary DSP Composer^™GUI development and pre-

production tuning tool. Processing chains may be designed

using a drag-and-drop interface to place/utilize functional

macro audio DSP primitives and custom audio filtering blocks.

The end result is a software image that is downloaded to the

DSP via serial control port.

—

Three Integrated hardware SRC blocks

Output can be master or slave

—

Supports dual-domain Fs on inputs (S/PDIF Rx and I S)

Supports dual-domain Fs on outputs (S/PDIF Tx and I S)

DSP programming could not be easier for the novice or small

engineering development group. DSP Composer provides the

programmer with faster time-to-market opportunities and the

ability to implement custom code.

DSP Tool Set w/ Private Keys Protect Customer IP

Integrated Clock Manager/PLL

—

Flexibility to operate from internal PLL, external crystal,

external oscillator

The CS47048 is available in a 100-pin LQFP package with

exposed pad for better thermal characteristics. Both

Input Fs Auto Detection w/ µC Acknowledgement
