CS4912  
Multi-Function Digital Audio Processor  
Features  
Description  
The CS4912 is a highly integrated and cost effective au-  
dio processing system for a variety of applications. This  
device integrates a 24-bit DSP with on-chip program and  
data RAM, a stereo DAC, a full-duplex serial audio inter-  
face, a digital audio transmitter, an asynchronous audio  
input port, a serial control port, and a phase-locked loop  
clock generator. The CS4912 may be coupled with an  
ADC such as the CS5331 for 2-in / 2-out audio applica-  
tions. A 2-in / 4-out system would include the CS4912  
and a stereo CODEC (CS4222), and a 4-in / 6-out sys-  
tem can be built using the CS4912 with two CODECs  
and a small amount of external logic.  
l 24-bit DSP with On-chip Program RAM, Data  
RAM, and Stereo DAC  
l 24x24 Multiplier with 48-bit Accumulator  
l CD Quality Stereo DAC with Output Filter  
2 ®  
l I C or SPI Serial Control Port  
l Integrated S/PDIF Digital Transmitter Port  
l Serial Audio Port, up to 4 In/6 Out  
l Asynchronous Audio Input Port  
l Programmable Phase Locked Loop  
l +5 Volt Only CMOS, 44-pin PLCC  
The CS4912 is configured for specific applications by  
DSP code loaded into the on-chip RAM. The device can  
be initialized by an external microcontroller, or booted di-  
rectly from a serial EEPROM using a small amount of  
external logic. The CRD4912 board is an evaluation plat-  
form for the CS4912, with complete documentation to  
simplify the design process. CS4912 application firm-  
ware kits are available for Car Audio Processing, Dolby  
Pro Logic Decoding, and Reverb/Effects applications.  
Ordering information for the application firmware kits is  
included in the CRD4912 data sheet.
