SYSTEM DEMONSTRATION PLATFORM (SDP)
The system demonstration platform (SDP) is a series of controller
boards, interposer boards, and daughter boards that can be used
for easy, low cost evaluation of Analog Devices, Inc., components
and reference circuits. It is a reusable platform whereby a single
controller board can be reused in various daughter board evalu-
ation systems.
Controller boards connect to a PC via a USB 2.0 high speed
port and provide a range of communication interfaces on a 120-
pin connector. The pinout for this connector is strictly defined.
A receptacle for this 120-pin connector is included on all SDP
daughter boards, component evaluation boards, and Circuits
from the Lab® reference circuit boards. There are two controller
boards in the platform: the SDP-B, which is based on the Blackfin®
ADSP-BF527, and the SDP-S, which is a serial interface only
controller board. The SDP-S has a subset of the SDP-B
functionality.
Interposer boards route signals between the SDP 120-pin con-
nector and a second connector. When the second connector is
also a 120-pin connector, the interposer can be used for signal
monitoring of the 120-pin connector signals. Alternatively, the
second connector allows SDP platform elements to be integrated
into a second platform, for example, the BeMicro SDK. More
information on the SDP can be found at www.analog.com/sdp.
