The CS4953xx DSP family are the enhanced versions of the

CS495xx DSP family with higher overall performance and

lower system cost. The CS4953xx includes all mainstream

audio processing codes in on-chip ROM. This saves external

memory for code storage. In addition, the intensive decoding

tasks of Dolby Digital

DTS-ES 96/24, THX Ultra2 Cinema and Dolby Headphone

can be accomplished without the expense of external

SDRAM memory.

With larger internal memories than the CS495xx, the

CS49531x is designed to support up to 150 ms per channel

of lip-sync delay. With 150 MHz internal clock speed, the

CS4953xx supports the most demanding post-processing

requirements. It is also designed for easy upgrading.

Customers currently using the CS495xx can upgrade to the

CS4953xx with minor hardware and software changes.
