EVAL-24LGA54EBZ

Product Details

The EVAL-24LGA54EBZ 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-24LGA54EBZ 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 (K1 to K17), allowing users to route signals, tie pins to ground, or configure the pins as needed. K7 to K13 support general input/output (I/O) or ground connections. The EVAL-24LGA54EBZ supports the following two logic control modes: parallel logic digital control using K14 to K17 or serial peripheral interface (SPI) from a connected Arduino board using K1 to K4. The logic control mode is selected through K5, where connecting it to GND enables parallel logic control mode and connecting it to VDD enables the MEMS switch SPI. The EVAL-24LGA54EBZ has Subminiature Version A (SMA) connectors (J1 to J11) 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. There are multiple power options on the board for providing power supplies to the evaluation board. A two-screw terminal connector can be used to provide VDD connection directly to the MEMS switch from an external supply or a regulated 3.3V derived from the Micro-USB connector or compatible Arduino board.

The full specifications of the device under test (DUT) are available in the corresponding product data sheet, which must be consulted with the EVAL-24LGA54EBZ user guide when using the EVAL-24LGA54EBZ.
