GENERAL DESCRIPTION
This user guide details the design, setup, and operation of the
EVA L -ADAU1467Z evaluation board. 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 SigmaStudio
section) rather than the ADAU1467, as shown in Figure 11.
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 EVA L-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.
