Product Brief
Benefits Overview
The Zoran
®
(ZR38601) is a high-performance, programmable digital audio
sig-nal processor capable of real-time, single-chip decoding of Dolby Digital
5.1- channel and MPEG-2 digital surround algorithms. It is the fourth genera-
tion decoder made by Zoran, based on the proven ZR38600 architectures.
The hardware block floating-point makes it optimum for Dolby Digital and
complex digital audio signal processing applications.
Due to its programmable high-performance and high level of integration, the
ZR38601 is unusually flexible in meeting a wide range of system require-
ments at the lowest possible system cost. At the low end, it can provide stan-
dard 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 pro-
vide eight channels of output, analog input, long-delay memories, custom
operating features, and the ability to be upgraded with downloaded

®
product enhancements. Yet all of this flexibility comes with-
out design complexity. Highly configurable standard functions with a simple
command structure minimize software development, while a full set of devel-
opment tools are available for the highly-custom product developer.
The ZR38601 is suitable primarily for audio applications such as Audio/Visual
home theater receivers, Digital Audio Broadcast (DAB), 3-D audio, six-chan-
nel speaker systems, and Karaoke processors; video applications like SDTV
and HDTV stereo television receivers and digital cable, and satellite TV set-
top boxes; and multimedia PC applications such as DVD players.
