ZR38601

The Zoran ZR38601 is a high performance programmable digital audio signal processor capable of real-time single-chip decoding of Dolby Digital AC-3 5.1-channel and MPEG2 digital surround algorithms. ZR38601 is the fourth generation decoder made by Zoran, being based on the proven ZR38000, ZR38500 and ZR38600 architectures. Hardware block floating-point makes it optimum for Dolby AC-3 and complex digital audio signal processing applications.

Because of its programmable high performance and high level of integration, the ZR38601 is unusually flexible in meeting a wide range of system requirements at the lowest possible system cost. At the low end it can provide standard fixed decoding functions with only a DAC and an optical interface for the S/PDIF input in addition to the oscillator crystal. At the high end it can provide eight channels of output, analog input, long-delay memories, custom operating features and the ability to be upgraded with downloaded SiliconSoftware™ product enhancements. Yet all of this flexibility comes without design complexity. Highly configurable standard functions with a simple command structure minimize software development, while a full set of development tools are available for the highly-custom product developer.

The ZR38601 is suitable for primarily audio applications such as Audio/Visual home theater receivers, Digital Audio Broadcast (DAB), 3-D audio, six-channel speaker systems and Karaoke processors; primarily video applications like SDTV and HDTV stereo television receivers, digital cable and satellite TV set-top boxes; and multimedia applications with both audio and video like Multimedia PCs and the Digital Video Disk (DVD) players.
