|Cirrus Logic Expands Analog-to-Digital Audio Converter Portfolio With
Focus on Integration, Premium Audio Quality|
AUSTIN, Texas – With a focus on superior
audio quality, Cirrus Logic Inc. has introduced the CS5368, an analog-to-digital (ADC) audio converter integrated
circuit (IC) that eliminates the need for incorporating multiple stereo analog-to-digital converters for
surround-sound or multichannel applications. Through feature integration, the CS5368 provides system designers with
a space-saving solution that streamlines product development, reduces design complexity and lowers overall system
cost compared to boards that use multiple stereo ADCs.
The CS5368 is the industry’s first eight-channel audio ADC
to feature a high-speed TDM interface, which provides a serial output of eight channels of audio data with sample
rates up to 192 kHz within a single data stream. This capability reduces layout constraints and relieves
input/output constraints on digital signal processors. Low latency digital filtering makes the CS5368 ideal for
live-sound and real-time audio applications.
“Through the CS5368’s advanced, fifth-order,
multi-bit Delta Sigma architecture and low-latency digital filtering, we were able to achieve superior audio
performance by preserving the integrity of the audio source,” said Jason Rhode, vice president, Mixed-Signal Audio
Products Division, Cirrus Logic. “These qualities make the CS5368 ideal for a wide variety of consumer and
professional audio applications, such as audio/video receivers, home theater systems, digital mixing consoles,
outboard audio converters, PC soundcards, external audio interfaces, DSP amplifiers and various automotive audio
Cirrus Logic also offers the IC in pin-compatible four- and six-channel options (CS5364
and CS5366), providing an easy upgrade path. Each IC provides an impressive 114 dB dynamic range and a negligible
low-noise measurement of –105 dB THD+N. The ICs also feature a differential architecture that provides excellent
noise rejection and performs sampling, analog-to-digital conversion and anti-alias filtering. Each IC also supports
all common PCM and TDM audio formats.
