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 Surround EX, AAC multi-channel,
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.
