MAX9400 Evaluation Kit
General Description
Features
ꢀ Controlled 50 Coplanar Traces
The MAX9400 evaluation kit (EV kit) contains the
MAX9400 low-skew quad buffer. The MAX9400 EV kit
runs at PECL/ECL and LVPECL/LVECL supplies at clock
rates up to 3.0GHz. The EV kit can be operated synchro-
nously with an external clock or asynchronously.
ꢀ Input Trace Lengths Matched to <2mils
ꢀ Output Trace Lengths Matched to <1mil
ꢀ Frequency Range
The EV kit is designed with 50 controlled-impedance
traces in a four-layer PC board. It can also be used to
evaluate the MAX9401–MAX9405.

Asynchronous Operation
Detailed Description
1) Verify that shunts are across pins 1 and 2 of
jumpers JU1 (SEL) and JU3 (EN) and pins 2 and 3
of jumpers JU2 (SEL) and JU4 (EN).
The MAX9400 EV kit contains an extremely fast, low-
skew quad LVECL/LVPECL or ECL/PECL buffer. The EV
kit demonstrates ultra-low propagation delay and chan-
nel-to-channel skew. The four channels can be operated
synchronously with an external clock, or in asynchro-
nous mode, depending on the state of the SEL input.
2) Connect two matched coax cables to the oscillo-
scope. Then connect the other end of the cables to
OUT1 and OUT1 on the MAX9400 EV kit board.
3) Connect the 2.0V power supply to the VCC pad. Set
the supply to 2.00V. Connect the supply ground to
the GND pad closest to VCC.
Power Supply
The MAX9400/MAX9402/MAX9403/MAX9405 are speci-
fied with outputs terminated with 50 to V
- 2V. In

4) Connect the -0.375V to -3.5V power supply to the
VEE pad. Set the supply to -1.3V. Connect the sup-
ply ground to the GND closest to VEE.
order to terminate the outputs with 50 to V

using the 50 oscilloscope input termination, V
is set

to 2.0V. The MAX9401/MAX9404 are specified with out-

CC
5) Connect two matched coax cables to the differential
signal generator that provides differential square
waves with the following setting:
ble swing outputs. In order to terminate the outputs with
50 to V - 3.3V, V is set to 3.3V. Table 1 lists the

d) Duty cycle = 50%
Enable and Select
EN, EN, SEL, and SEL can be controlled by either
jumpers or external signals. The MAX9400 EV kit can
provide internal DC logic signals to EN, EN, SEL, and
SEL by using jumpers JU1, JU2, JU3, and JU4. Table 2
lists jumper JU3 and jumper JU4 functions. Table 3 lists
jumper JU1 and jumper JU2 functions. The EV kit can
also be controlled by external signals using EN, EN,
SEL, and SEL connectors. Before connecting external
signals to the EN, EN, SEL, SEL connectors, verify
there are no shunts across jumpers JU1–JU4.
6) Connect the other end of the cables to IN1 and IN1.
7) Turn on the two power supplies, enable the function
generator, and verify the differential output signal
(V
OUT1
- V
) is greater than 500mV.
OUT1
To evaluate other channels, make sure the correspond-
ing output termination resistors on the EV kit board are
removed and the unused outputs are terminated.
To eliminate signal distortion, use the matched same-
length input cables, and use the matched same-length
output cables.

MAX9400 Evaluation Kit
Evaluating the MAX9401–MAX9405
The MAX9400 EV kit is a four-layer PC board with 50
controlled-impedance input traces with 50 termination
(two parallel 100 resistors). All output signal traces
are also 50 controlled-impedance traces (with 49.9
termination resistors).

•
To evaluate the MAX9401, replace the MAX9400EHJ
with a MAX9401EHJ.
•
To evaluate the MAX9402, replace the MAX9400EHJ
with a MAX9402EHJ and remove output termination
resistors R1 to R8. The output is half-amplitude
compared to an open output because of the volt-
age-divider formed by the on-chip series 50 and
the 50 oscilloscope input.
