GENERAL DESCRIPTION
The EVAL-ADGS5414SDZ is the evaluation board for the ADGS5414. The ADGS5414 is a latch-up proof, octal single-pole, single-throw (SPST) switch controlled by a serial peripheral interface (SPI). The SPI has robust error detection features, including cyclic redundancy check (CRC) error detection, invalid read/write address detection, and serial clock (SCLK) count error detection. It is possible to daisy-chain multiple ADGS5414 devices together, which enables the configuration of multiple devices with a minimal amount of digital lines. The ADGS5414 also supports burst mode, which decreases the time between SPI commands. Figure 1 shows the EVAL-ADGS5414SDZ in a typical evaluation setup. The EVAL-ADGS5414SDZ is controlled by the EVAL-SDP-CB1Z system demonstration platform (SDP), which connects to a PC via a USB port. The ADGS5414 is on the center of the evaluation board, and wire screw terminals are provided to connect to each of the source pins and drain pins. Three screw terminals power the device, and a fourth terminal provides users with a defined digital logic supply voltage, if required. Alternatively, the digital logic supply voltage can be supplied from the SDP board. Full specifications of the ADGS5414 are available in the ADGS5414 data sheet available from Analog Devices, Inc., and must be consulted in conjunction with this user guide when using the evaluation board. The evaluation board interfaces to the USB port of a PC via the SDP board. The EVAL-SDP-CB1Z board (SDP-B controller board) is available to order on the Analog Devices website at www.analog.com.

EVALUATION BOARD HARDWARE

POWER SUPPLIES

Connector J1 provides access to the supply pins of the ADGS5414. VDD, GND, and VSS on the J1 terminal block link to the appropriate pins on the ADGS5414. For dual-supply voltages, the evaluation board can be powered from ±9 V to ±22 V. For single-supply voltages, the GND and VSS terminals must connect together and power the evaluation board with 9 V to 40 V. Additionally, 3.3 V is supplied to the VL pin of the ADGS5414 by the SDP board when Link LK1 is in Position B. When con-trolling the ADGS5414 by a method other than the SDP board, supply between 2.7 V and 5.5 V to the VL pin of the ADGS5414 via the EXT_VL screw terminal input on Connector J1. Link LK1 must be in Position A.

INPUT SIGNALS

Four screw connectors, J2, J3, J5, and J6 , are provided to connect to both the source and drain pins of the ADGS5414. Additional SubMiniature version B (SMB) connector pads are available if extra connections are required. Each trace on the source and drain side includes two sets of 0603 pads, which can place a load on the signal path to ground. A 0 Ω resistor is placed in the signal path and can be replaced with a user defined value. The resistor combined with the 0603 pads can create a simple resistor-capacitor (RC) filter.
LINK OPTIONS
A number of link options are provided on the EVAL-ADGS5414SDZ evaluation board that must be set for the required operating conditions before using. Table 1 shows the positions of the links to control the evaluation board via the SDP board using a PC and external power supplies. The functions of these link options are described in detail in Table 2. When using the SDP board in conjunction with the EVAL-ADGS5414SDZ, Link LK1 must be in Position B to avoid damage to the SDP board.

EVALUATION BOARD SOFTWARE

INSTALLING THE SOFTWARE

The EVAL-ADGS5414SDZ evaluation board uses the Analog Devices Analysis Control Evaluation (ACE) software. ACE is a desktop software application that allows the evaluation and control of multiple evaluation systems. ACE installs the necessary SDP drivers and .NET Framework 4 by default. Install ACE before connecting the SDP board. The ACE software and access to full instructions on how to install and use ACE can be found on the Analog Devices website. After the installation is finished, the EVAL-ADGS5414SDZ evaluation board plug-ins appear when opening ACE.
INITIAL SETUP
To set up the evaluation board, complete the following steps:

1. Connect the evaluation board to the SDP board and connect the SDP board to the computer via a USB cable.

2. Power the evaluation board as described in the Power Supplies section.

3. Run the ACE application. The EVAL-ADGS5414SDZ board plug-ins appear in the attached hardware section of the Start tab.

4. Double-click on the evaluation board plug-in to open the evaluation board view shown in

BLOCK DIAGRAM AND DESCRIPTION

The EVAL-ADGS5414SDZ software is organized so that it appears similar to the functional block diagram shown in the ADGS5414 data sheet. In this way, the user can correlate the functions on the EVAL-ADGS5414SDZ board with the description in the data sheet. A full description of each block, register, and setting is given in the ADGS5414 data sheet. Figure 4 shows a full screen block diagram with some of the blocks labelled. The functionality of these blocks, which pertain to the evaluation board, are described in Table 3.

The INVALID RW ENABLE , SCLK COUNT ENABLE , and CRC ENABLE check boxes enable or disable the error detection features on the SPI interface.

The BURST MODE ENABLE check box enables or disables burst mode.

The RW ERROR FLAG , SCLK ERROR , and CRC ERROR FLAG indicators illuminate red if the relevant error flags assert in the error flags register.

The Clear Flags button clears the error flags register.

The Apply Changes button applies all modified values to the devices.

MEMORY MAP

All registers are fully accessible from the Memory Map tab, which allows registers to be edited at a bit level (see Figure 5 and Figure 6). The bits shaded in dark gray are read-only bits and cannot be accessed from ACE. All other bits are toggled. The Apply Changes button transfers data to the device.All changes in this tab correspond to the block diagram; for example, if the internal register bit is enabled, it displays as enabled on the block diagram. Any bits or registers that are bold are modified values that have not been transferred to the evaluation board. After clicking Apply Changes, the data are transferred to the evaluation board.
