MAX13042E Evaluation Kit
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 ±15kV 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–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.
