SAA7715H Digital Signal Processor

The SAA7715 is a cost effective and powerful high performance 24-bit programmable DSP for a variety of digital Audio applications. This DSP device integrates a 24-bit DSP core with programmable Memories (program RAM/ROM, data and coefficient RAM), 4 digital serial inputs, 4 digital serial outputs, 2 separate SPDIF receivers, a stereo FSDAC, a standard Philips IC-bus Interface a phase-locked loop for the DSP Clock generation and a second phase-locked loop for system Clock generation (internal and external DAC clocks).The SAA7715 CAN be configured for various Audio applications by downloading the dedicated DSP program code into the DSP program RAM or using the ROM or a combination of both. During the ,Power-down mode, the contents of the Memories and all other settings will keep their values. The SAA7715 CAN be initialized using the IC-bus Interface Several system application examples, based on this existing SAA7715, are available for a wide range of Audio applications (e.g car Radio DSP DVD post-processing, Dolby Pro Logic PC USB Audio and more) which CAN be used as a reference design for customers.
