MAX3971/MAX3971A Evaluation Kits
_______________ General Description
The MAX3971/MAX3971A evaluation kits (EV kits)
simplify evaluation of the MAX3971 10.3Gbps limiting
amplifier and the MAX3971A 10.7Gbps limiting amplifier.
The EV kit enables testing of all the device's functions.
SMA connectors with 50
controlled impedance
connections to the MAX3971/MAX3971A are provided for
all data input and output ports to facilitate connection to
high-speed test equipment.

Note: Please indicate that you are using the
MAX3971/MAX3971A when ordering from these
suppliers.
_________________________ Quick Start
1) Connect a +3.3V power supply to J6 (VCC).
Connect the power supply ground to J7.
2) For the MAX3971, apply a 10.3Gbps, 10mV
P-P
to
800mV
P-P
differential signal between J1 (IN+) and
J2 (IN-). For the MAX3971A, apply a 10.7Gbps,
5mV
P-P
to 800mV
P-P
differential signal between J1
(IN+) and J2 (IN-)
3) Connect a jumper from the center pin to the
ground pin of JU1 to enable the output.
4) Connect a 50
oscilloscope to the SMA
connectors J3 and J4 (OUT+, OUT-) to observe
the output of the limiter. The output signal is
approximately 250mV
P-P
.
_______________________________ Notes
At high frequencies such as from 1GHz to 10GHz,
delays with the board and cables affect measurements.
Mismatches in cables can cause significant
measurement errors. Edge speeds are best observed
by using single-ended methods. Careful calibration of
cables, attenuators, and the board is necessary.
