ZR38650
SRS TruSurround. They work with either two- or six-channel
inputs and the AC-3 or MPEG decoders.
Bass Management
Selected low-frequencies can be redirected to different
speakers with Bass Management. Useful with all types of
decoding to compensate for the types of speakers used.
DVD - Linear PCM
Special provisions are included for data formats and synchroni-
zation for AC-3/MPEG decoding with 3-D audio and bass
management for Digital Video Disk (DVD) applications.
Hall Effects/Music Modes
Adds the natural acoustical effects of a performance environ-
ment to the original recording environment.
Home THX5.1
Theater THX for use in consumer home entertainment systems.
Karaoke Processing
Voice cancellation, pitch-shifting and echo and reverberation.
Custom Functions, Etc.
Product designers can always add custom functions and varia-
tions, often with very simple software additions.
Operation and Set-Up Functions
These control the simple start and stop operation of the
decoding functions and determine the initial hardware operation
and configuration.
System Functions
These functions control the real-time operation including inter-
face transactions, program loading and in-circuit testing.
System Configurations
The ZR38650 is highly self-contained and can work with few
external parts as shown in Figure 1. However it is very flexible in
accommodating the needs of larger, higher performance
systems. Figure 2 shows all of the possible options that are sup-
ported to make a complete system.
Hosts
The ZR38650 does not require a host microprocessor but if
there is one in the system it may be used to advantage. Either
the bit-serial SPI (Small Peripheral Interface) or Z2C interface,
or a byte-wide parallel interface may be used.
Data Input/Output
The encoded digital input data stream can use a bit-serial or
byte-parallel interface or S/PDIF receiver with the ZR38650
either a master or slave. Up to six-channels of analog signals
can be input in bit-serial ADC (Analog-to-Digital Converter)
formats in a master or slave mode.
