maxim integrated 4 component list detailed description of hardware the max14591 ev kit is a fully assembled and tested circuit board that demonstrates the functionality of the max14591 high-speed, open-drain capable logic-level translator in both the 8-bump wlp and 8-pin tdfn pack - ages. the ev kit features enables direct evaluation of the device by multiple jumper-selectable methods. the highly configurable pcb allows the user to evaluate each package separately or both at once. input power to the ev kit is provided by a micro-usb, type-b connector or an external 5v power supply. on-board ldo regulators provide the appropriate voltage for each component, and potentiometers allow the user to adjust the power supply for either side of the level translator independently. the ev kits pcb is designed with 1oz copper. power supply the ev kit is powered by a user-supplied 5v external dc power supply connected between the vbus test point (tp26) and gnd, or the usb bus provided at the micro- usb connector (j1). the power supply is then converted into three independent voltages. the pin-selectable output voltage of the max8902a (u3) provides a 4.6v supply for peripherals such as the nc7wz07 open-drain buffer, as well as for the ds1090 econoscillators?. two separate max8902b ics are used to generate the power for the v cc and v l supplies on the max14591. the v cc sup- ply is generated by u6, which also provides power to the push-pull buffer for the v cc channels (u10). the v l sup- ply is generated by u7, which also provides power to the push-pull buffer for the v l channels (u8). on-board oscillators the ev kit features two on-board oscillators to generate input signals to the device. the ds1090-1 (u5) is used to generate a potentiometer-adjustable clock from 4mhz to 8mhz, while the ds1090-16 (u4) generates a poten - tiometer adjustable clock from 250khz to 500khz. these clock signals can be connected to individual channels using 4-way jumpers jp2, jp5, jp12, and jp17 (table 1). push-pull and open-drain evaluation each channel can be driven in either push-pull mode or open-drain mode. for evaluation of push-pull operation or low-speed open-drain operation, use the on-board oscil - lators. simply connect the open-drain buffer or push-pull buffer through one of the 4-way jumpers to the channel to be driven to begin evaluation. see table 1 for jumper configurations. for high-speed open-drain operation, an external function generator is required. econoscillator is a trademark of maxim integrated products, inc. designation qty description c1, c3, c4, c6, c9, c11 6 10f 10%, 6.3v x5r ceramic capacitors (0805) c2, c5, c10 3 0.01f 10%, 16v x7r ceramic capacitors (0603) c7, c8, c12, c13Cc18 8 0.1f 10%, 16v x7r ceramic capacitors (0603) c14, c19 2 1f 10%, 16v x5r ceramic capacitors (0603) d1 1 red led (0805) stanley electric br1112h-tr j1 1 micro usb, type-b receptacle hirose zx62d-b-5pa8 jp1, jp3, jp7, jp9Cjp11, jp13Cjp15, jp18Cjp23, jp25 16 2-pin, single-row headers designation qty description jp2, jp5, jp12, jp17 4 4-pin headers jp4, jp6, jp24 3 3-pin, single-row headers pot1, pot2 2 500k? 10%, 0.25w potentiometers murata pv37w504c01b00 pot3, pot4 2 50k? 10%, 0.25w potentiometers murata pv37w503c01b00 r1 1 470? 5% resistor (0805) r2 1 1.5k? 1% resistor (0805) r3 1 120k? 1% resistor (0805) r4, r5 2 43k? 5% resistors (0805) r6 1 80.6k? 1% resistor (0805) r7 1 68k? 1% resistor (0805) www.maximintegrated.com evaluates: max14591 max14591 evaluation kit
