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,

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.

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

3.6V) logic levels and guarantees data rates up to

100Mbps. The MAX13042E also features ±15kV ESD

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

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.

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–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.
