DSPB56720CAG

The Symphony DSP56720/DSP56721 Multi-Core Audio Processors, including the DSPB56720CAG, are programmable CMOS DSPs designed for demanding audio applications. These processors utilize multiple DSP56300 24-bit cores to deliver high performance, making them suitable for automotive, consumer, and professional audio systems.

The DSPB56720CAG is clocked at 200MHz per core and operates at 3.3V. It offers 744kB of on-chip memory and supports various interfaces including Host Interface, I²C, SAI, and SPI. The device is housed in a 144-LQFP (20x20 mm) package and is designed for surface mounting.

These DSPs excel in processing high-definition audio standards like Dolby Digital+, Dolby TrueHD, and DTS-HD, and can handle multiple audio streams. They provide a wide range of on-chip audio processing functions, including decoding algorithms, equalization, compression, and signal generation. The DSPB56720 variant specifically includes an external memory interface, allowing for off-chip memory expansion and interfacing with external parallel peripherals.

Potential applications include A/V receivers, HD-DVD and Blu-Ray players, car audio/amplifiers, and professional recording equipment. The high MIPs capability and memory requirements are driven by the need to process complex audio data for modern entertainment systems and professional audio tasks such as recording, signal processing, and digital audio synthesis.
