Analog Devices Inc. EVAL-ADGS1412SDZ Board for ADGS1412 SPI Switch

Analog Devices Inc. EVAL-ADGS1412SDZ Evaluation Board is a demonstration and evaluation tool for the ADGS1412 SPI (Serial Peripheral Interface) Switch. The SPI has robust error detection features. These are 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 ADGS1412 devices together. This enables the configuration of multiple devices with a minimal amount of digital lines. The ADGS1412 also supports burst mode that decreases the time between SPI commands.

The EVAL-ADGS1412SDZ is controlled by the EVAL-SDP-CB1Z System Demonstration Platform which connects to a PC via USB. The ADGS1412 is on the center of the evaluation board, and wire screw terminals are provided to connect to each of the source and drain pins. Three screw terminals power the device and a fourth terminal provides users defined digital logic supply voltage, if required. Alternatively, the digital logic supply voltage can be supplied from the EVAL-SDP-CB1Z.

Analog Devices Inc. EVAL-ADGS1412SDZ 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. The ACE installer installs the necessary SDP drivers and .NET Framework 4 by default. Install ACE before connecting the SDP. The ACE software can be found on the Analog Devices website.
