suppliers.
_________________________ Quick Start
1)
2)
Connect a +3.3V power supply to J6 (VCC).
Connect the power supply ground to J7.
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-)
Connect a jumper from the center pin to the
ground pin of JU1 to enable the output.
Connect a 50鈩?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.
