The CS49400 DSP integrates a multi-channel audio decoder and a

32-bit audio processor with an audio optimized software

framework—it’s the ideal, economical solution for AV receivers.

Feature rich AVR designs can be easily developed using this

framework, which includes both certified application programs and

a modular programming envionment for easy customization. The

framework includes state-of-the-art audio decoders and audio

enhancement programs, such as DTS-ES 96/24, Dolby Digital, AAC,

and THX. Framework API along with a comprehensive suite of

development tools is available for manufacturers to incorporate

unique sound processing.

The CS49400 DSP was designed to reduce system costs while

providing features and flexibility for competitive system level

solutions. It provides system level peripherals and internal

memory—helping to drive down system costs. Difficult processing

tasks of AAC, DTS-ES 96/24, and THX Cinema can be accomplished

without the expense of external logic or memory. This DSP can meet

the needs of I/O intensive designs supporting up to 12 input

channels and 16 output channels. The CS49400 is an economical

solution for a variety of applications including AV receivers, outboard

decoders, DVD receivers, and DVD Audio/Video/SACD players.
