Evaluates: MAX14724 MAX14724PMB1 Peripheral Module General Description EV Kit Contents The MAX14724PMB1 peripheral module provides the Peripheral module containing a MAX14724 necessary hardware to interface the MAX14724 8:4 matrix switch multiplexer to any system that utilizes Quick Start 2 Pmod-compatible expansion ports configurable for I C Required Equipment or SPI communication. The IC can be powered from a MAX14724PMB1 single 1.6V to 5.5V supply or dual 2.5V supplies. The 2 device features an 8:4 multiplexer that every switch I C or SPI host 2 combination can be selected through using I C or Power supply SPI. Refer to the MAX14724 IC data sheet for detailed Procedure information regarding the operation of the IC. The EV kit is fully assembled and tested. Follow the steps Features below to verify board operation: 8:4 Matrix Switch Multiplexer 1) Connect 2.5V to V+ TP2. Connect -2.5V to V- TP1. 2 (or use the voltage available on your I C/SPI host on 50 Controlled-Impedance Signal Traces J3, V+ pin 12 on J3, V- pin 10 on J3) 12-Pin Pmod-Compatible Connector 2 2) Connect 2.5V or the VL of I C/SPI host to VL, pin 11 Proven PCB Layout of J3 header. 2 Fully Assembled and Tested 3) Connect I C or SPI host to J3. 2 2 4) Connect I C/CS (pin 1 of J3) high for I C, low for SPI. Pmod is a trademark of Digilent Inc. 2 5) The switches can be controlled through I C or SPI. See MAX14724 datasheet for detail. Ordering Information appears at end of data sheet. MAX14724PMB1 Evaluation Kit Board 19-7642 Rev 1 2/19Evaluates: MAX14724 MAX14724PMB1 Peripheral Module easy impedance matching. The device can be programmed Detailed Description 2 by using I C or SPI. The MAX14724PMB1 peripheral module provides a The J1 connector provides connection to NO ports (see convenient way to evaluate the MAX14724 multiplexer. All PCB signal traces are 50 controlled impedance to allow Table 1), while the J2 connector provides connection to COM ports (see Table 2). Table 1. Connector J1 The MAX14724PMB1 can interface to the host by plugging 2 directly into a Pmod-compatible port (configured for I C or PIN SIGNAL SPI) through connector J3 (see Table 3). 1 NO1 2 NO2 Table 2.
