New High-performance D/A Converters are
Ideal for SACD & DVD-Audio Systems
Designed for Multichannel Applications
These new Cirrus Logic
digital-to-analog converters provide
precisely what designers need in today's
multichannel audio applications. They
deliver premium analog performance and
sound quality by utilizing low-latency digital
filtering, fifth-order, multi-bit, Delta-Sigma
digital-to-analog conversion, logarithmic
digital-volume control and switched-
capacitor analog filtering. Both ICs use
patented automatic mode selection based
on sample rate detection to support PCM
data at sample rates from 4 kHz to 192
kHz, and a dedicated interface is included
for DSD audio data. Design the CS4385
(8-channel), and CS4365 (6-channel) into
your next-generation home theater
systems, high-performance sound cards,
SACD and DVD players, A/V receivers,
automotive audio systems, mixing
consoles, and effects processors.

For SACD applications, these D/A
converters include a patented Direct
Stream Digital processor, which includes a
volume-control engine that does not
decimate the data stream, thereby
maintaining the native sampling rate of
2.8224 MHz and preserving the integrity of
the SACD data format. Also included is an
on-chip 50 kHz filter that complies with
recommendations in the SACD standards.
Cirrus Logic's techniques for providing
SACD volume control and filtering offers
manufacturers the ability to add SACD at
no additional cost in the analog section of
their products.
Ease of design, a high level of integration,
and a flexible feature set allows
manufacturers to minimize time to market
while maximizing performance and
consumer affordability.
