amplifiers, the AD8065. Included on the evaluation board is a
10 V reference, the ADR01. An external reference can also be
applied via an SMB input. The evaluation kit consists of a CD-
ROM with self-installing PC software to control the DAC. The
software allows the user to write a code to the device.

SYSTEM DEMONSTRATION PLATFORM
The system demonstration 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
EVAL-AD5415/AD5449SDZ TO SPORT INTERFACE
The Analog Devices SDP has one SPORT serial port. The
SPORT interface is used to control the AD5449, allowing clock
frequencies of up to 30 MHz.
OPERATING THE EVALUATION BOARD
The board requires ±12 V and +5 V supplies. The +12 V V
and −12 V V
supply is used to power the DAC (V
Both supplies are decoupled to their respective ground plane
with 10 µF tantalum and 0.1 µF ceramic capacitors.

The
MICROWIRE, and most DSP interface standards. Data is
written to the device in 16-bit words. Each 16-bit word consists
of four control bits and 12 data bits for the AD5449. Control
bits allow control of various functions on the DAC.
MICROPROCESSOR INTERFACING
Microprocessor interfacing to the
serial bus that uses a standard protocol compatible with micro-
controllers and DSP processors.
The system demonstration platform (SDP) is a hardware and
software platform that provides a means to communicate from
the PC to Analog Devices products and systems that require
digital control and/or readback. The SDP has a Blackfin
processor (BF5xx) at its core.
The ADSP-BF5xx processor incorporates channel synchronous
serial ports (SPORT) and general purpose input/output pins
(GPIO). A serial interface between the BlackFin processor and
