GENERAL DESCRIPTION
This user guide describes the E VA L-SDP-CS1Z system
demonstration platform-serial (SDP-S) controller board from
Analog Devices, Inc. The SDP-S controller board is part of the
Analog Devices system demonstration platform (SDP). The
SDP consists of a series of controller boards, interposer boards,
and daughter boards. SDP controller boards provide a means
of communicating with the system under evaluation from the
PC. Interposer boards route signals between two connectors.
Daughter boards are a collection of product evaluation boards
and Circuits from the Lab™ reference circuit boards. The SDP-S
is used as part of the evaluation system for many Analog Devices
components and reference circuits. The primary audience for
this user guide is the system engineer who seeks to understand
how to set up the SDP-S board and begin USB communications
to the PC.
The SDP-S board is designed to be used in conjunction with
various Analog Devices component evaluation boards and
Circuits from the Lab reference circuits as part of a customer
evaluation environment. The SDP-S provides USB connectivity
through a USB 2.0 high speed connection to the computer,
allowing users to evaluate components on this platform from a
PC application. The SDP-S is based on a USB-to-serial engine,
which has SPI, I2C, and GPIO lines available, with a 120-pin
small footprint connector.
This user guide provides instructions for installing the SDP-S
hardware (EVAL-SDP-CS1Z board) and software onto a
computer. The necessary installation files are provided with the
evaluation daughter board package. The Getting Started section
provides software and hardware installation procedures, PC
system requirements, and basic board information. The Evaluation
Board Hardware section provides information on the EVAL-
SDP-CS1Z components. The EVAL-SDP-CS1Z schematics are
provided in the Evaluation Board Schematics section.

GETTING STARTED
This section provides specific information to assist with using
the SDP-S board as part of the user’s evaluation system.
The following topics are covered:
•PC configuration
•USB installation
•Powering up/powering down the SDP-S
PC CONFIGURATION
For correct operation of the SDP board, the user’s computer
must have the following minimum configuration:
•Windows XP Service Pack 2 or Windows Vista®
•USB 2.0 port
When removing the SDP-S board from the package, handle the
board carefully to avoid the discharge of static electricity, which
can damage some components.
USB INSTALLATION
Perform the following tasks to safely install the SDP-S board
onto the computer. There are two stages in the software
application installation procedure. The first stage installs the
application software. The second stage installs the .NET
Framework 3.5 and the necessary drivers.
Installing the Software
1. Run the application installation file provided. The first
stage installs the application GUI and the necessary
support files onto the computer.
2. Immediately following the application installation, the
.NET Framework 3.5 and the driver package for the SDP
board are installed. If the .NET Framework 3.5 is already
preinstalled on the computer, this stage is skipped and
Step 2 consists of a driver package installation only.
Connecting the SDP-S Board to the PC
Attach the SDP-S board to a USB 2.0 port on the computer via
the Standard-A-to-Mini-B cable provided.
Verifying Driver Installation
Before using the SDP-S board, verify the driver software has
installed properly.
Open the Windows Device Manager and verify the SDP-S
board appears under ADI Development Tools, as shown in
Figure 2.

POWER
The SDP-S board is powered by the USB connector. It does not
require power to be supplied by the daughter board. The SDP-S
board provides 3.3 V at 20 mA on Pin 116 (VIO_3.3) to connected
daughter boards as the VIO voltage for the daughterboard.
Pin 5 (USB_VBUS) is connected to the 5 V line of the USB
connector, providing 5 V ±10% as an output of the SDP board.
DAUGHTER BOARD DESIGN GUIDELINES
The daughter board design guidelines specify the layout,
connector positioning, keep out areas, and dimensions of
potential daughter boards. This guidance is to ensure that a
daughter board can connect to any controller board from
the SDP family. Following these guidelines ensures that the
connector on the SDP-S or any other controller board in the
SDP family can have any one of the available daughter boards
physically attached.
Connector Location
The daughter board connector and securing screw holes are
located in the top left hand corner. This arrangement for a
daughter board is shown in Figure 5.
If a daughter board exceeds these dimensions, it may not be
possible to connect it to the other controller or interposer
boards in the SDP family. Every effort was made to extend the
5.9 mm dimension as large as possible to allow space for vias
between the connector and the edge of the board. These are
absolute maximum dimensions and must not be exceeded.
The full specification drawing for the connector location on the
daughter board is shown in Figure 6.
The mating daughter board 120-pin connector is the Hirose
FX8-120S-SV(21), 120-pin receptacle, FEC 132-4660, Digi-Key
H1219-ND. Consult the connector data sheet for full details on
the connector. Note that Pin 1 to Pin 60 are placed on the left
side of the connector and Pin 61 to Pin 120 are placed on the
right side of the connector.
