NORWOOD, Mass. (Business Wire EON) March 27, 2008 --
Analog Devices, Inc. (ADI), today introduced two audio
processors for HDTV sound that provide uninterrupted, high-fidelity
audio connectivity from a variety of digital and analog home
entertainment sources. The ADAV4601 and ADAV4622 audio processors expand
ADI’s Advantiv™
advanced television solutions portfolio to provide complete,
cost-effective, fully programmable audio solutions that speed delivery
of audio enhancements in flat-panel plasma and LCD HDTV designs. With a
single ADAV46xx-based audio platform, engineers can support multiple TV
designs ─ from high-end to low-end ─
without costly system redesign, reducing time-to-market by up to several
weeks.
Offering unit costs that are comparable with fixed-function audio
processors, the fully programmable ADAV46xx family gives OEMs the
flexibility to customize their advanced audio subsystems, or to use
default settings for fixed-function audio processing. In addition to
supporting the latest audio standards used in HDTVs, the new audio
processors provide the capability for supporting post-sale software
updates and enable TV manufacturers to easily add performance
enhancements or remedy TV model hardware and software issues.
“The flat-panel TV market has shifted into
high-gear, so manufacturers must deliver advanced audio functions across
numerous product lines, price targets and industry standards,”
said Bill Bucklen, director, Advanced Television Segment, Analog
Devices. “The ADAV46xx family enables audio
engineers to deliver lifelike sound that compensates for the
space-constrained speakers in today’s
flat-panel LCD and plasma TVs. At the same time, ADI’s
new audio processors provide support for important end-user system
firmware upgrades that are critical in helping to reduce product returns
and minimize costs.”
Combined with high-performance, multi-channel, 24-bit analog-to-digital
converters (ADCs), digital-to-analog converters (DACs) and an integrated
multi-channel, pulse-width modulator (PWM), the ADAV46xx family delivers
all the subsystem functionality required for an advanced TV audio
implementation. Designed to work with ADI’s
latest High-Definition Multimedia Interface™
(HDMI™) receivers and Class-D power stages,
the new audio processors eliminate annoying pops and clicks that can
disrupt audio clarity. The ADAV46xx also includes an external mute pin,
allowing designers to provide pop/click reduction during system
start-up, change audio sources seamlessly and deliver the high-quality
audio required to match today’s
high-definition (HD) video.
The enhanced processors provide full support for digital and analog
baseband audio, as well as multi-standard analog broadcast demodulation
and decoding for worldwide broadcasting standards such as BTSC, EIAJ,
A2-Korea, A2-Europe, and NICAM. The ADAV4622 includes an integrated
broadcast audio processor with an auto-standard-detecting (ASD)
processor, which reduces design time and costs over competing offerings
that require external SIF circuitry for broadcast standard detection and
switching.
The ADAV46xx audio processors provide advanced audio features such as a
dedicated TV audio flow that incorporates full matrix switching of any
input to any output; automatic volume control for compensating for
volume changes during advertisements or when switching channels; dynamic
bass, a multiband equalizer; and up to 200 ms of stereo delay memory for
audio/video synchronization. Leveraging Analog Devices’
award-winning SigmaStudio™
DSP graphical programming tool, audio systems engineers can easily build
flexible digital audio platforms by selecting from ADI’s
library of royalty-free audio enhancement algorithms and support for
popular third-party audio algorithms.
Pricing and Availability
The ADAV4601 and ADAV4622 audio processors are available now in
full-production quantities. The processors ship in 14-mm ×
14-mm LQFP (low-profile quad flat package) packages and are pin-for-pin
and software-register compatible. The ADAV4601 is priced at $3.85 per
unit and the ADAV4622 is priced at $4.75 per unit, both in 10,000-piece
quantities. For more information, visit http://www.analog.com/pr/ADAV4601
