CS470xx Data Sheet

The CS470xx 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 CS470xx further simplifies system design and

reduces total system cost by integrating the S/PDIF Rx,

S/PDIF Tx, analog inputs, analog outputs, and SRCs. For

example, a hardware SRC can down-sample a 192 kHz

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.

FEATURES

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 highest precision 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

Target applications are:

Integrated 5:1 analog mux feeds one stereo ADC

— Automotive Head Units & Outboard Amplifiers

— Automotive Processors & Automotive Integration Hubs

— Digital TV

— MP3 Docking Stations

— AVR and DVD RX

Configurable Serial Audio Inputs/Outputs

†

—

Integrated 192 kHz S/PDIF Rx

Integrated 192 kHz S/PDIF Tx

Supports 32-bit Serial Data @ 192 kHz

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

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

Bars)

†

—

TDM I/O modes (Up to 10/8 channels per line)

Supports Different Fs Sample Rates

The CS470xx is programmed using the simple yet powerful

†

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 S/PDIF vs. I S inputs

DSP Tool Set w/ Private Keys Protect Customer IP

Integrated Clock Manager/PLL

The Cirrus Framework^™programming environment offers

Assembly and C language compilers and other software

development tools for porting existing code to the CS470xx

family platform.

—

Flexibility to operate from internal PLL, external crystal,

external oscillator

Input Fs Auto Detection w/ µC Acknowledgement

Host Control & Boot via I²C^™or SPI^™Serial Interface

Configurable GPIOs and External Interrupt Input

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

Low-power Mode

The CS470xx is available in a 100-pin LQFP package with

exposed pad for better thermal characteristics. Both

^{Commercial (0}°C to +70°C) and Automotive (-40°C to

⁺⁸⁵°C) temperature grades.

Ordering Information:
