Audio Decoder 128-Pin LQFP Tray

The CS497024 DSP family is an enhanced version of the CS4953xx DSP family with higher overall performance. In addition to all the mainstream audio processing codes in onchip ROM that the CS4953xx DSP offers, the CS497024 device family also supports the decoding of major high-definition audio formats. Additionally, the CS497024, a dual-core device, performs the high-definition audio decoding on the first core, leaving the second core available for audio post-processing and audio enhancement. The CS497024 device supports the most demanding audio post processing requirements. It provides an easy upgrade path to systems currently using the CS495xx or CS4953xx device with minor (or no) hardware and software changes.
