MAX13047E Evaluation Kit
Before beginning, the following equipment is needed:
• MAX13047E EV kit
• +5V, 100mA DC power supply
• Two-channel oscilloscope (i.e., Tektronix TDS3012)
The MAX13047E EV kit is fully assembled and tested.
Follow the steps below to verify the board operation.
Caution: Do not turn on power supply until all con-
nections are made.
1) Verify that all jumpers are in their default positions,
2) Connect the positive terminal of the +5V supply to
3) Connect the first channel of the oscilloscope to the
4) Connect the second channel of the oscilloscope to
5) Turn on the DC power supply.
6) Observe the oscilloscope and verify that the +1.8V
The MAX13047E EV kit provides a proven design to
evaluate the MAX13047E dual-bidirectional low-level
translator. The MAX13047E translates between VL and
VCC logic levels for data rates up to 16Mbps (8MHz).
The MAX13047E EV kit includes the convenience of on-
board clock generators capable of producing 8MHz
and 4MHz signals on the I/O_VL1 and I/O_VCC1

supply to the GND pad.
I/O_VL1 pad, which is the +1.8V logic-level 8MHz
signal input.
the I/O_VCC1 pad, which is the +3V logic-level
8MHz signal output.
logic-level 8MHz I/O_VL1 signal is translated to the
+3V logic level at the I/O_VCC1 pad.

inputs, and 1MHz on the I/O_VL2 and I/O_VCC2 inputs.
Move the shunt of JU1 to the 1-2 position to set the
clock generator to 8MHz and move the shunt to the 2-3
position for 4MHz.
To have both channels transferring data at the same
speed, place a shunt on JU6 or JU7 depending on the
input direction. If I/O_VL_ is the input, place the shunt
in the 1-2 position of JU6. If I/O_VCC_ is the input,
place the shunt in the 1-2 position of JU7. It is impor-
tant when channels are tied together to remove shunts
from JU3 or JU4 depending on the preferred clock
rate. If the 8MHz or 4MHz speed is selected, remove
the shunts from JU4. If the 1MHz speed is selected,
remove the shunt from JU3.
When translating from VL to VCC, move JU2, JU3, and
JU4 to the 1-2 position. To go from VCC to VL, move
JU2, JU3, and JU4 to the 2-3 position.
The MAX13047E can enter shutdown mode by moving
JU5 to the 2-3 position. Otherwise, leave the shunt at
the 1-2 position for normal operation.
The EV kit allows user-supplied input signals to be
applied to the I/O_VL_ and I/O_VCC_ pads. It is impor-
tant to remove the shunts from JU3 and JU4 to avoid
signal conflicts with the clock generators.
The EV kit is powered completely from one power sup-
ply by default. Users can supply their own VL and VCC
voltages by moving JU8 and JU10 to the 2-3 position.
Apply a voltage from +1.1V to +3.6V or (VCC + 0.3V) to
the VL and GND pads and +1.65V to +5.5V to the VCC
and GND pads.
Users can apply a +3V to +5.5V power supply to the
VCLK and GND pads once JU8 is moved to the 2-3
position.
