The ADAU1463/ADAU1467 are automotive qualified audio processors that far exceed the digital signal processing capabilities of earlier SigmaDSP® devices. They are codecompatible with each other, as well as the ADAU1450/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), multi-rate processing, and block processing paradigms. The graphical programming tool, SigmaStudio™ 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 instructions per sample at the standard sample rate of 48 kHz. Powerful clock generator hardware, including a flexible PLL with multiple fractional integer outputs supports all industry standard audio sample rates, non-standard 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 has a fully asynchronous clock domain capable of operating as either clock master or slave. In addition, each serial port supports multiple data lines. Each of the eight pins SDATAIO pin may be associated with any of the four input or four output serial ports. Serial ports with multiple data pins use a single bit clock and frame clock to transmit or receive additional channels of audio data. This allows more channels of audio I/O without the need to run serial ports at high speeds. It also enables serial audio communication with multiple synchronous peripherals. The additional data pins can carry from two to eight channels. 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 ADCs, DACs, digital audio devices, amplifiers, and control circuitry with highly configurable serial ports, I2C, SPI, S/PDIF interfaces, and multipurpose input/output pins. Dedicated decimation filters can decode the PDM output of up to four MEMS microphones.
The ADAU1463/ADAU1467 have independent I2C/SPI slave and master control ports. This allows them both to be programmed and controlled by an external master device such as a microcontroller, and program and control slave peripherals directly. Self-boot functionality and the master control port enable complex standalone systems.

Evaluation Kits (1)
This board is suitable for the evaluation of, and software development for, the ADAU1467 and ADAU1463 SigmaDSP® processors. Note that the ADAU1467 and the ADAU1463 are functionally identical; however, the ADAU1467 has more program and data memory than the ADAU1463. When using this evaluation board to evaluate the ADAU1463, select the ADAU1463 block (see the Setting Up Communications in SigmaStudio section) rather than the ADAU1467, as shown in Figure 16. Performing this action informs the compiler to limit the amount of memory allocated to match the ADAU1463. All other procedures and instructions in this user guide are identical for the ADAU1463 and ADAU1467.
This evaluation board provides access to the digital serial audio ports of the ADAU1467. Four analog inputs and eight analog outputs are provided by the AD1937 codec included in the evaluation kit. Switches enable the evaluation of alternate features provided by many of the pins with multiplexed functionality, and numerous headers provide access to serial audio ports and the master and slave control ports. These selectable modes and headers make the EVAL-ADAU1467Z well suited to prototyping larger application circuits, as well as initial device evaluation. The ADAU1467 core is programmed using Analog Devices, Inc., SigmaStudio® software, which interfaces to the evaluation board via a USB interface (USBi). The on-board, electronically erasable programmable read only memory (EEPROM) can be programmed for self boot mode. The evaluation board is powered by a 6 V dc supply, which is regulated to the voltages required on the board. The printed circuit board (PCB) is a 4-layer design with a ground plane and a power plane on the inner layers. The evaluation board includes connectors for external analog inputs and outputs and optical Sony/Philips Digital Interface (S/PDIF) interfaces. The master clock is provided by the integrated oscillator circuit and the on-board 12.288 MHz passive crystal.
For full details, see the ADAU1467 and AD1937 data sheets, which must be used in conjunction with this user guide when using the evaluation board.
