CS4923/4/5/6/7/8/9  
Multi-Channel Digital Audio Decoders  
l CS4923/4/5/6/7/8 features  
Description  
— Optional Virtual 3D Output  
The CS4923/4/5/6/7/8 is a family of multi-channel digital  
audio decoders, with the exception of the CS4929 as the  
only stereo digital audio decoder. The CS4923/4/5/6 are  
designed for Dolby Digital and MPEG-2 Stereo decoding. In  
addition the CS4925 adds MPEG-2 multi-channel decoding  
capability and the CS4926 provides DTS decoding. The  
CS4927 is an MPEG-2 multi-channel decoder and the  
CS4928 is a DTS multi-channel decoder. The CS4929 is an  
AAC 2-channel and MPEG-2 stereo decoder. Each one of  
the CS4923/4/5/6/7/8/9 provides a complete and flexible  
solution for multi-channel (or stereo in the case of the  
CS4929) audio decoding in home A/V receiver/amplifiers,  
DVD movie players, out-board decoders, laser-disc players,  
HDTV sets, head-end decoders, set-top boxes, and similar  
products.  
— Simulated Surround and Programmable Effects  
®
— Real Time Autodetection of Dolby Digital ,  
®
DTS , MPEG Multi-Channel and PCM  
— Flexible 6-channel master or slave output  
l CS4923/4/5/6/7/8/9 features  
— IEC60958/61937 transmitter for compressed-  
data or linear-PCM output  
— Dedicated 8 kilobyte input buffer  
— DAC clock via analog phase-locked loop  
— Dedicated byte wide or serial host interface  
— Multiple compressed data input modes  
— PES layer decode for A/V synchronization  
— 96-kHz-capable PCM I/O, master or slave  
— Optional external memory and auto-boot  
— +3.3-V CMOS low-power, 44-pin package  
l CS4923/4/5/6 features  
Cirrus Logic’s Crystal Audio Division provides a complete set  
of audio decoder and auxiliary audio DSP application  
programs for various applications. For all complementary  
analog and digital audio I/O, Crystal Audio also provides a  
complete set of high-quality audio peripherals including:  
multimedia CODECs, stereo A/D and D/A converters and  
IEC60958 interfaces. Of special note, the CS4226 is a  
complementary CODEC providing a digital receiver, stereo  
A/D converters, and six 20-bit DACs in one package.
