EVALUATION BOARD

The EVAL-AD5543/EVAL-AD5553 is used in conjunction with

an SDP1Z system development platform board available from

Analog Devices, which is purchased separately from the

evaluation board. The USB-to-SPI communication to the

AD5543 is completed using this Blackfin-based development

board. The software offers a waveform generator.

SYSTEM DEVELOPMENT PLATFORM

The system development platform (SDP) is a hardware and

software evaluation tool for use in conjunction with product

evaluation boards. The SDP board is based on the Blackfin

BF527 processor with USB connectivity to the PC through a

USB 2.0 high speed port. For more information about this

device, see the system development platform web page.

AD5543/AD5553 TO SPORT INTERFACE

The Analog Devices SDP has one SPORT serial port. The

SPORT interface is used to control the AD5543/AD5553,

allowing clock frequencies up to 30 MHz.

WAVEFORM GENERATOR

The evaluation board software offers a waveform generator to

show every change introduced and transmitted to the output.

OPERATING THE EVALUATION BOARD

The evaluation board requires ±12 V and +5 V supplies. The
