Analog Devices, Inc., 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.
The ADAV46xx family delivers lifelike sound that compensates for the space-constrained speakers in today’s flat-panel LCD and plasma TVs. 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 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.
