MAX13042E Evaluation Kit
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 VL and VCC logic levels and guarantees data rates up to 100Mbps. As configured, the EV kit dedicates two channels for translation between VL to VCC and two channels for translation between VCC to VL. 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 VL range is 1.62V to 3.2V and the ±15kV ESD-protected VCC range is 2.2V to 3.6V.

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 The MAX13042E EV kit circuit features I/O traces of matched length (within 5 mils) to maintain propagationtime uniformity. The EV kit dedicates two channels for translation between VL to VCC and two channels for translation between VCC to VL. Input signals can either be applied using SMA connectors IVL1, IVL2, IVCC3, and IVCC4 or at test points TP1–TP4. Output signals are monitored using oscilloscope probe jacks OVCC1, OVCC2, OVL3, and OVL4. The EV kit also utilizes the MAX13042E’s enable function through configuration of jumper JU1.
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, 3VP-P square wave with a 1.5V offset.
Enable Input
Jumper JU1 controls the enable input of the MAX13042E. See Table 1 for JU1 jumper selection.
Table 1. Enable (EN) Pin Setting (Jumper JU1)
SHUNT POSITION 1-2* 2-3 ENABLE PIN (EN) Connected to VL EV KIT FUNCTION Enabled (normal operation)
Connected to GND Disabled (tri-state operation)
*Default position.
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 terminated. See Table 2 for SMA input termination settings. Signal traces will remain of matched length in this configuration.

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 VL (1.62V to 3.2V) and VCC (2.2V to 3.6V) logic levels and guarantees data rates up to 100Mbps. The MAX13042E also features ±15kV ESD protection on all I/O VCC lines.
*Default position. **Must configure signal generator for high-impedance output.
Test Point Input Option (TP1–TP4)
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.
