external oscillator
Input Fs Auto Detection w/ C 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 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.
Target applications are:
— Automotive Head Units & Outboard Amplifiers
— Automotive Processors & Automotive Integration Hubs
— Digital TV
— MP3 Docking Stations
— AVR and DVD RX
— DSP Controlled Speakers (e.g. Subwoofers, Sound
Bars)
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.
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.
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.
