The CS4970xx Family are single-chip, 32-bit audio DSPs designed to meet the demanding processing tasks associated with high-definition audio standards of next-generation DVD systems from Blu-ray®. The CS4970xx decodes up to six surround-sound audio algorithms, including Dolby Digital, Dolby Digital Plus, Dolby TrueHD, DTS Digital Surround, DTS-HD Master, DTS-HD High Resolution Audio and DTS Express any of which may be featured within high-definition DVD disc media. With its 32-bit, dual-core structure, the CS4970xx 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 CS4970xx adeptly manages via an advanced phase-lock-loop (PLL) that generates a system clock source. The CS4970xx also offers such post-processing algorithms as Dolby Pro Logic IIx, DTS 96/24, DTS Neo:6, MPEG-2 AAC LC 5.1 Channel, SRS Circle Surround II, Dolby Headphone, Dolby Virtual Speaker, SRS TruSurround XT and THX® Ultra2, which are built into the IC’s on-chip ROM. The CS4970xx also provides support for HDMI 1.4a, 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. Support for home audio applications is through a third party. Please contact your local sales representative for information.
