EVAL-24LGA33EBZ

Product Details

The EVAL-24LGA33EBZ enables easy evaluation of the 24-lead land grid array (LGA) MEMS switches in the Switches and Multiplexers Portfolio that are purchased separately. The board is supplied with a socket to secure a 24-lead LGA micro electromechanical systems (MEMS) switch to the evaluation board without the need for soldering.

Figure 1 shows the EVAL-24LGA33EBZ evaluation board. A 24- lead LGA MEMS switch can be easily inserted into the central socket of the evaluation board that is designed for flexible testing of various switch configurations. Each MEMS switch pin connects to a header (K2 to K23), allowing users to route signals, tie pins to ground, or configure the pins as needed. The EVAL-24LGA33EBZ supports two logic control modes: parallel logic control using K20 to K23, or serial peripheral interface (SPI) control from a connected Arduino board using the link headers named OPT_SDO, OPT_SCLK, OPT_CSB, and OPT_SDI. The Arduino shield connectors (P4 to P7) mate the board directly to an Arduino form factor controller.

The EVAL-24LGA33EBZ has Subminiature Version A (SMA) connectors (J1 to J24) that connect directly to the MEMS switch pins and are used for signal access, allowing users to easily apply or monitor control signals during testing. Two two-screw terminal blocks are provided. The VDD terminal supplies the device supply rail from an external source, and the VCP terminal connects to the MEMS switch VCP pin, serving as either an input or an output.

The full specifications of the device under test (DUT) are available in the corresponding product data sheet, which must be consulted with the EVAL-24LGA33EBZ user guide when using the EVAL-24LGA33EBZ.
