The ADAU1463/ADAU1467 are automotive qualified audio processors that far exceed the digital signal processing capabilities of earlier SigmaDSP? devices. They are pin and register compatible with each other, as well as with theADAU1450/ADAU1451/ADAU1452 SigmaDSP? processors. The restructured hardware architecture is optimized for efficient audio processing. The audio processing algorithms support a seamless combination of stream processing (sample-by-sample), multirate processing, and block processing paradigms. The SigmaStudio? graphical programming tool enables the creation of signal processing flows that are interactive, intuitive, and powerful. The enhanced digital signal processor (DSP) core architecture enables some types of audio processing algorithms to be executed using significantly fewer instructions than were required on previous SigmaDSP generations, leading to vastly improved code efficiency.The 1.2 V, 32-bit DSP core can run at frequencies of up to 294.912 MHz and execute up to 6144 single instruction, multiple data (SIMD) instructions per sample at the standard sample rate of 48 kHz. Powerful clock generator hardware, including a flexible phase-locked loop (PLL) with multiple fractional integer outputs, supports all industry standard audio sample rates. Nonstandard rates over a wide range can generate up to 15 sample rates simultaneously. These clock generators, along with the on-board asynchronous sample rate converters (ASRCs) and a flexible hardware audio routing matrix, make the ADAU1463/ADAU1467 ideal audio hubs that greatly simplify the design of complex multirate audio systems.The ADAU1463/ADAU1467 have four input serial ports and four output serial ports. Each device has an asynchronous clock domain capable of operating as either a bit clock and frame sync master or slave. Each of the serial ports supports multiple data lines. The eight SDATAIOx pins each can be associated with any of the four input or four output serial ports. The use of assignable data pins allows a serial port to transmit or receive additional channels of audio data using a single bit clock and frame clock. Each of the supplemental data pins can carry from two to eight channels of serial audio. This flexible configuration provides more channels of audio input/output (I/O) without the need to run serial ports at high speed, and enables systems with additional serial audio peripherals. These expanded serial audio ports, along with the clock generators, the on-board asynchronous sample rate converters (ASRCs), and a flexible hardware audio routing matrix make the ADAU1463/ ADAU1467 ideal audio hubs that greatly simplify the design of complex, multirate audio systems.The ADAU1463/ADAU1467 interface with a wide range of analog-to-digital converters (ADCs), digital-to-analog converters (DACs), digital audio devices, amplifiers, and control circuitry with highly configurable serial ports, I2C, serial peripheral interface (SPI), Sony/Philips Digital Interconnect Format (S/PDIF) interfaces, and multipurpose I/O pins. Dedicated decimation filters can decode the pulse density modulation (PDM) output of up to four MEMS microphones.Independent slave and master I2C/SPI control ports allow the ADAU1463/ADAU1467 to be programmed and controlled by an external master device such as a microcontroller, and to program and control slave peripherals directly. Self boot functionality and the master control port enable complex standalone systems.Note that throughout this data sheet, multifunction pins, such as SDATAIO4/MP20, are referred to either by the entire pin name or by a single function of the pin, for example, MP20, when only that function is relevant.Applications Automotive audio processing Head units Distributed amplifiers Rear seat entertainment systems Trunk amplifiers Commercial and professional audio processing
