CS49700

The CS49700 is a single-chip, 32-bit audio processor designed to meet the demanding processing tasks associated with high-definition audio standards of next-generation DVD systems from Blu-Ray? and HD-DVD?. The CS49700 decodes up to six surround-sound audio algorithms, including Dolby Digital, Dolby Digital Plus, Dolby TrueHD, DTS, DTS Master and DTS High Resolution, any of which may be featured within high-definition DVD disc media.

With its 32-bit, dual-core structure, the CS49700 generates true parallel processing power of 1.8 giga operations per second (300 million instructions per second). Multiple audio formats also present myriad clock frequency challenges, to which the CS49700 adeptly manages via an advanced phase-lock-loop (PLL) that generates a system clock source.

The CS49700 also offers such post-processing algorithms as Dolby Pro Logic IIx, DTS 96/24, Neo:6, MPEG, AAC, SRS Circle Surround II, Dolby Headphone, Dolby Virtual Speakers, SRS Tru-Surround XT and THX? Ultra2, which are built into the IC's on-chip ROM.

The CS49700 also provides support for HDMI 1.3, the emerging digital audio and video interconnect standard that is used to send digital audio and video signals among home theater equipment, such as A/V receivers, DVD players and flat-panel televisions.
