GENERAL DESCRIPTION

This user guide describes the EVAL-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 EVALSDP-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

Run the application installation file provided. The first stage installs the application GUI and the necessary support files onto the computer.
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.

POWERING UP/POWERING DOWN THE SDP-S

The following sections describe how to safely power up and power down the SDP-S.

Powering Up the SDP-S Board

Each interface provided by the SDP-S is available on unique pins of the SDP-S 120-pin connector. The connector pin numbering scheme is outlined in Figure 4.

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.

Keep Out Area
To allow the greatest flexibility for future controller boards, a keep out area is established for components higher that 3 mm.
The keep out area is 12.65 mm wide and extends down the entire left side of the daughter board.

Restriction on Right Angle Connectors
Due to the layout of other boards in the SDP family, and their daughter boards, right angle connectors are not allowed on the top and left edges of the daughter boards and (if required) should be placed on the right or bottom edges. A right angle connector describes any connector that requires the connection to protrude over the edge of the board (for example, right angle SMB or screw terminal).

MECHANICAL SPECIFICATIONS

The mechanical specifications of the SDP-S board are 2.36 inch × 0.87 inch (60 mm × 22 mm). The tallest component on the top is approximately 0.17 inch (4.3 mm), and the tallest components on the bottoms are the 120-pin connectors at approximately 0.152 inch (3.86 mm). Refer to Figure
