general description the max14589e/max14594e/max14689 evaluation kits (ev kits) are fully assembled and tested circuit boards that demonstrate the functionality of the max14589e, max14594e, and max14689 double-pole double-throw (dpdt) analog switches in a 9-bump wafer-level pack - age (wlp). the features of the ev kits enable evaluation of the analog switches through audio jack inputs and outputs, as well as sma connectors for ac characteristic evaluation. input power to the ev kits is provided by a micro-usb, type-b connector or an external power supply. features and benefts proven pcb layout ? decrease evaluation time fully assembled and tested sma and 3.5mm audio jack connectors ? directly evaluate ac characteristics through sma connectors ? quickly evaluate audio performance with 3.5mm audio jack connectors usb 5v power with on-board adjustable ldo 19-6809 ; rev 0; 9/13 ordering information appears at end of data sheet. quick start required equipment max14589e, max14594e, or max14689 ev kit usb power supply or 1.8v to 5.5v power supply audio source (e.g., mp3 player, computer, etc.) external speakers or headphones with 3.5mm audio jack procedure the ev kits are fully assembled and tested. follow the steps below to verify board operation and begin evaluation: 1) if using a usb power supply to power the board through the micro-usb connector (j1), verify that a shunt is installed shorting pins 3-4 on jumper ju2. this powers the device from the output of the on-board ldo. to adjust the ldo output voltage, connect a voltmeter at test point t3 and turn the screw on the potentiometer (r3) until reaching the desired value. to use the raw bus voltage as the power supply for the device, place the shunt so that it is shorting pins 5-6 on ju2. 2) if an external power supply is used, apply the power at test point t2 and use the shunt to short pins 1-2 on ju2 to provide power to the parts from the external supply. 3) verify that jumper ju1 has a shunt installed shorting pins 2-3, and that jumper ju4 has a shunt installed shorting pins 2-3. installing the shunts in these locations provides power from the source to the v cc pin of the device. 4) verify that jumper ju3 has a shunt installed shorting pins 1-2. this shorts the control bit (cb) on the device to gnd, electrically connecting nc1 to com1 and nc2 to com2. 5) connect an audio source to the normally closed audio jack (p2), using the male-to-male 3.5mm audio cable included with the ev kit. 6) connect external speakers or headphones to the common audio jack (p3). 7) when the audio source outputs the audio signal, and ju3 has a shunt shorting pins 1-2, the audio signal should be heard on the speakers or headphones connected at p3. 8) move the shunt on ju3 from pins 1-2 to pins 2-3. the audio signal should no longer be heard on the speak - ers or headphones connected at p3. 9) if the audio source connection moves from the normally closed audio jack (p2) to the normally open audio jack (p1) with a shunt in position 2-3 on ju3, the audio signal on the common audio jack (p3) is heard on the speakers or headphones. if the shunt on ju3 is in position 1-2, there is no audio signal heard on the speaker or headphones. evaluate: max14589e/max14594e/ max14689 max14589e/max14594e/ max14689 evaluation kits
maxim integrated 2 detailed description of hardware the max14589e, max14594e, and max14689 ev kits are fully assembled and tested circuit boards that demon - strate the functionality of the max14589e, max14594e, and max14689 dtdt analog switches in a 9-bump wlp. the ev kit features enables evaluation of the analog switches through audio jack inputs and outputs, as well as sma connectors for ac characteristic evaluation. input power to the ev kits is provided by a micro-usb, type-b connector or an external power supply. the ev kit pcbs are designed with 1oz copper. power supply the ev kits are powered by a user-supplied 1.6v to 5.5v external dc power supply connected between v ext and gnd, the raw usb bus supplied at the micro-usb connector (j1), or the regulated output of the ldo (u2) that is powered by the usb bus. ac evaluation the ev kits have a secondary ic configured for evaluation of the ac characteristics of the device. sma connectors (j2Cj5) allow for direct connection to a network analyzer. 50 i termination resistors (r6, r7) provide termination to match the typical 50 source resistance of the network analyzer, allowing for easy evaluation of these parameters. the ability to connect external dc bias voltages at test points t7 and t8 further simplifies evaluation of ac characteristics, while using a network analyzer that cannot provide dc offset voltages. v bus status led an indicator diode (d1) is included on the ev kits, indicating that a v bus voltage is present on the micro- usb connector (j3). if the led glows green, power is present at j3 and the board can be powered by the ldo output or by the raw v bus supply (see table 1 for jumper configurations). the status led does not glow when a voltage is present on test point t2. table 1. jumper settings (j6, j7, ju1Cju4) *default position. jumper shunt position description j6 1-2 connects nc1 on u2 to dc bias applied at test point t7 through a 475k? resistor 3-4 connects com1 on u2 to dc bias applied at test point t7 through a 475k? resistor j7 1-2 connects nc2 on u2 to dc bias applied at test point t8 through a 475k? resistor 3-4 connects com2 on u2 to dc bias applied at test point t8 through a 475k? resistor ju1 1-2 connects v cc of u1 to gnd; places u1 in shutdown mode 2-3* connects v cc of u1 to the power-supply bus; places u1 in normal, powered operation ju2 1-2 connects the external power supply applied at t2 to the power-supply bus 3-4* connects the regulated ldo output to the power-supply bus 5-6 connects raw v bus voltage from the usb to the power-supply bus ju3 1-2* connects cb of u1 and u2 to gnd; nc_ and com_ are electrically connected 2-3 connects cb of u1 and u2 to v cc ; no_ and com_ are electrically connected ju4 1-2 connects v cc of u2 to gnd; places u3 in shutdown mode 2-3* connects v cc of u2 to power supply bus; places u3 in normal, powered operation www.maximintegrated.com evaluate: max14589e/max14594e/ max14689 max14589e/max14594e/ max14689 evaluation kits
