Product Details

The third generation of SHARC® Processors, which includes the ADSP-21261, ADSP-21262, ADSP-21266, ADSP-21267, ADSP-21363, ADSP-21364, ADSP-21365, and ADSP-21366 offers increased performance, audio and application-focused peripherals, and memory configurations capable of supporting surround-sound decoder algorithms. All devices are pin-compatible with each other and completely code-compatible with all prior SHARC Processors. These members of the SHARC Processor family are based on a single-instruction, multiple-data (SIMD) core, which supports both 32-bit fixed-point and 32-/40-bit floating-point arithmetic formats making them particularly suitable for high-performance audio applications.

The ADSP-21366 offers the highest performance – 333 MHz/2 GFLOPs -- within the third generation SHARC Processor family. This level of performance makes the ADSP-21366 particularly well suited to address the increasing requirements of the consumer, professional, and automotive audio market segments. In addition to its higher core performance, the ADSP-21366 includes additional value-added peripherals such as an S/PDIF transmitter/receiver, and 8-channel asynchronous sample rate converter.

Third generation SHARC Processors also integrate application-specific peripherals designed to simplify hardware design, minimize design risks, and ultimately reduce time to market. Grouped together, and broadly named the Digital Audio Interface (DAI), these functional blocks may be connected to each other or to external pins via the software-programmable Signal Routing Unit (SRU). The SRU is an innovative architectural feature that enables complete and flexible routing amongst DAI blocks. Peripherals connected through the SRU include, but are not limited to, serial ports, SPI ports, S/PDIF Tx/Rx, and an 8-Channel asynchronous sample rate converter block.

SHARC Melody Platform for Home Theater

The SHARC Melody platform combines high-performance processors with optimized software, thus offering complete audio solutions to the consumer audio marketplace. The ADSP-21366, through on-chip ROM, offers industry standard audio decoder & post-processing algorithms such as:

  • PCM
  • Dolby Digital*
  • Dolby Digital EX2*
  • Dolby Pro Logic IIx*
  • DTS 5.1*
  • DTS ES*
  • DTS Neo:6*
  • DTS 96/24*
  • SRS Focus*
  • MPEG2 AAC LC
  • MP3
  • Graphic Equalizer
  • Balance/Fader
  • Bass Management
  • Delay Management
  • These algorithms are factory mask-programmed, ensuring that single-chip system implementations are realized and system bill of materials costs are minimized.

    * License agreement required from IP holders prior to receipt of silicon samples.

    Customers must be licensed for the appropriate Dolby and DTS technologies which exist in the on-chip ROM. Minimum annual volume requirements apply.
    Please contact your local Analog Devices sales office for more information regarding the use of these products.
