Analog Devices has announced its third generation of 32-bit SHARC Digital Signal Processors designed specifically for audio processing in automotive and consumer electronics applications.
With a total of 6Mbits of internal memory, the ADSP-21266 is targeted at the AVR market where on-chip support for a large number of audio decoders and postprocessors is required.
The ADSP-21267 is a lower-cost version of the ADSP-21266 and offers 4Mbits of on-chip memory to very cost-sensitive car audio market segments.
The ADSP-21364, with its high-performance sample rate converters, is targeted at the professional audio market while the ADSP-21365 is targeted at mid- and upper-level car audio applications.
In addition to Dolby ProLogic IIx and Microsoft WMA 9 Pro, the new SHARC Processors support the full range of high-resolution audio formats, including PCM 96 kHz, Dolby Digital, Dolby Digital EX, DTS Discrete 6.1, DTS-ES Matrix 6.1, DTS 96/24 5.1, DTS Neo:6, MPEG2, MPEG2 AAC and SRS. These audio algorithms enable functionality such as 7.1-channel audio, bass management and 96 kHz sampling rates to support the latest DVD formats.
The SHARC ADSP-21266 is sampling today and will be in production in Q1 2004. The ADSP-21267 and ADSP-21365 will be sampling in Q1 2004, and the ADSP-21364 will be sampling Q2 2004.
Per-unit pricing in quantities of 10,000 units for the ADSP-21267 is $9.95, for the ADSP-21266 is $14.95, for the ADSP-21365 is $19.95, and for the ADSP-21364 is $24.95.
