general description the max13042e evaluation kit (ev kit) demonstrates the max13042e 4-channel, bidirectional logic-level translator, featured in a tiny 12-bump ucsp package. the max13042e translates between v l and v cc logic levels and guarantees data rates up to 100mbps. as configured, the ev kit dedicates two channels for translation between v l to v cc and two channels for translation between v cc to v l . the ev kit gives the option of using sma connectors or test points at the input signal lines, while providing scope probe jacks for monitoring the outputs. the v l range is 1.62v to 3.2v and the ?5kv esd-protected v cc range is 2.2v to 3.6v. features ? supply voltage ranges 1.62v to 3.2v (v l ) 2.2v to 3.6v (v cc ) ? ?5kv esd protection on i/o v cc lines ? two dedicated channels to allow translation from v l to v cc ? two dedicated channels to allow translation from v cc to v l ? 100mbps guaranteed data rates ? enable input ? sma inputs and 5mm scope probe jack outputs ? 12-bump ucsp (1.54mm x 2.12mm) package ? fully assembled and tested evaluates: max13042e max13042e evaluation kit ________________________________________________________________ maxim integrated products 1 19-1015; rev 1; 2/08 component list for pricing, delivery, and ordering information, please contact maxim direct 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. ordering information component suppliers + denotes lead-free and rohs-compliant. note: indicate that you are using the max13042e when con- tacting these component suppliers. ucsp is a trademark of maxim integrated products, inc. part type MAX13042EEVKIT+ ev kit designation qty description c1, c2 2 0.1? ?0%, 16v x7r ceramic capacitors (0402) murata grm155r71c104k tdk c1005x7r1c104k c3 1 1? ?0%, 6.3v x5r ceramic capacitors (0402) murata grm155r60j105k tdk c1005x5r0j105k ivl1, ivl2, ivcc3, ivcc4 4 sma pcb vertical mounts ju1 1 3-pin header ju2?u5 4 2-pin headers ovcc1, ovcc2, ovl3, ovl4 4 5mm scope probe jacks r1?8 8 0 resistors (0603) r9?12 4 49.9 ?% resistors (0402) tp1?p4 0 not installed, test points u1 1 4-channel, bidirectional logic-level translator (12-bump ucsp, 1.54mm x 2.12mm) maxim max13042eebc+ (top mark: adq) 5 shunts 1 pcb: max13042e ev kit+ supplier phone website m ur ata m fg . c o., ltd .770- 436- 1300 www.murata.com tdk corp. 847- 803- 6100 w w w .com p onent.td k.com
evaluates: max13042e quick start recommended equipment before beginning, the following equipment is needed: 1.62v to 3.2v dc power supply 2.2v to 3.6v dc power supply logic function generator oscilloscope standard 5mm scope probe procedure the max13042e ev kit is fully assembled and tested. follow the steps below to verify board operation. caution: do not turn on the power supply until all connections are completed. 1) verify that a shunt is installed on jumper ju1 between pins 1-2 (normal operation). 2) set the logic function generator to produce a 1mhz, 2v p-p , 1v offset square wave. disable the logic function generator output. 3) connect the logic function generator to sma input ivl1. terminate function generator as necessary. 4) connect the positive terminal of the 2v supply to the vl pcb pad and the ground terminal to the gnd pcb pad. 5) connect the positive terminal of the 3v supply to the vcc pcb pad and the ground terminal to the gnd pcb pad. 6) place an oscilloscope probe at scope jack output ovcc1. 7) enable the power supplies and the logic function generator output. 8) verify that ovcc1 shows a 1mhz, 3v p-p square wave with a 1.5v offset. detailed description the max13042e ev kit demonstrates the max13042e 4-channel, bidirectional logic-level translator, featured in a tiny 12-bump ucsp package. the max13042e translates between v l (1.62v to 3.2v) and v cc (2.2v to 3.6v) logic levels and guarantees data rates up to 100mbps. the max13042e also features ?5kv esd protection on all i/o v cc lines. the max13042e ev kit circuit features i/o traces of matched length (within 5 mils) to maintain propagation- time uniformity. the ev kit dedicates two channels for translation between v l to v cc and two channels for translation between v cc to v l . input signals can either be applied using sma connectors ivl1, ivl2, ivcc3, and ivcc4 or at test points tp1?p4. output signals are monitored using oscilloscope probe jacks ovcc1, ovcc2, ovl3, and ovl4. the ev kit also utilizes the max13042e? enable function through configuration of jumper ju1. enable input jumper ju1 controls the enable input of the max13042e. see table 1 for ju1 jumper selection. sma inputs (ivl1, ivl2, ivcc3, and ivcc4) to utilize the sma connectors to apply input signals to the ev kit, these connections must be appropriately ter- minated. see table 2 for sma input termination set- tings. signal traces will remain of matched length in this configuration. test point input option (tp1?p4) to implement use of the test point inputs, remove the appropriate resistor (r1, r2, r7, or r8) and apply a signal to the corresponding test point. signal traces will remain of matched length in this configuration. gnd pads are conveniently located on the ev kit to ground the input signal. note: the input signal is not as well matched as it is with the sma inputs. max13042e evaluation kit 2 _______________________________________________________________________________________ shunt position enable pin (en) ev kit function 1-2* connected to v l enabled (normal operation) 2-3 connected to gnd disabled (tri-state operation) table 1. enable (en) pin setting (jumper ju1) * default position. shunt position input termination installed 49.9 termination not installed* none** table 2. sma input termination (jumpers ju2?u5) * default position. ** must configure signal generator for high-impedance output.
