EVAL-ADAU1467Z UG-1134 One Technology Way P.O. Box 9106 Norwood, MA 02062-9106, U.S.A. Tel: 781.329.4700 Fax: 781.461.3113 www.analog.com Evaluating the ADAU1463 and ADAU1467 SigmaDSP Audio Processors FEATURES GENERAL DESCRIPTION 4 analog inputs This user guide details the design, setup, and operation of the 8 analog outputs EVAL-ADAU1467Z evaluation board. This board is suitable for Stereo S/PDIF input and output the evaluation of, and software development for, the ADAU1467 Self boot EEPROM and ADAU1463 SigmaDSP processors. Note that the ADAU1467 Headers for interfacing to off board peripherals and the ADAU1463 are functionally identical however, the ADAU1467 has more program and data memory than the EVALUATION KIT CONTENTS ADAU1463. When using this evaluation board to evaluate the EVAL-ADAU1467Z evaluation board ADAU1463, select the ADAU1463 block (see the Setting Up EVAL-ADUSB2EBZ (USBi) communications adapter Communications in SigmaStudio section) rather than the USB cable with Mini-B plug ADAU1467, as shown in Figure 16. Performing this action informs 6 V ac to dc power supply the compiler to limit the amount of memory allocated to match the ADAU1463. All other procedures and instructions in this HARDWARE REQUIRED user guide are identical for the ADAU1463 and ADAU1467. PC running Windows XP, Windows Vista, or Windows 7 This evaluation board provides access to the digital serial audio Analog, stereo audio source with an output cable terminated ports of the ADAU1467. Four analog inputs and eight analog with a 3.5 mm (1/8 inch) plug (for the analog input) outputs are provided by the AD1937 codec included in the Headphones, desktop speakers, or audio input with a cable evaluation kit. Switches enable the evaluation of alternate terminated with a 3.5 mm (1/8 inch) plug (for the analog features provided by many of the pins with multiplexed output) functionality, and numerous headers provide access to serial S/PDIF audio source and receiver, each with optical cables audio ports and the master and slave control ports. These terminated with TOSLINK connectors (for digital selectable modes and headers make the EVAL-ADAU1467Z input/output) well suited to prototyping larger application circuits, as well as SOFTWARE REQUIRED initial device evaluation. The ADAU1467 core is programmed SigmaStudio software, available for download from the using Analog Devices, Inc., SigmaStudio software, which SigmaStudio product page interfaces to the evaluation board via a USB interface (USBi). The on-board, electronically erasable programmable read only DOCUMENTS NEEDED memory (EEPROM) can be programmed for self boot mode. ADAU1467 data sheet The evaluation board is powered by a 6 V dc supply, which is AD1937 data sheet regulated to the voltages required on the board. The printed AN-1006 Application Note 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.
