MAX3665 Evaluation Kit
General Description
The MAX3665 evaluation kit (EV kit) simplifies evalua-
tion of the MAX3665 transimpedance preamplifier. The
EV kit includes a circuit that emulates the zero-to-peak
current input signal that would be produced by a pho-
todiode. It also includes a calibration circuit that allows
accurate bandwidth measurements.
The MAX3665 EV kit is fully assembled and tested.

Note:
Please indicate that you are using the MAX3665 when
contacting these component suppliers.
Quick Start
1) Connect a signal source to INPUT. Set the signal
amplitude to 50mVp-p (this may require some attenu-
ation between the source and the MAX3665 EV kit).
The signal should have a data rate up to 622Mbps.
2) Connect OUT+ and OUT- to the 50鈩?inputs of a
high-speed oscilloscope.
3) Remove shunts from jumpers JU1 and JU2.
4) Connect a +3.3V or +5.0V supply to the VCC termi-
nal and ground to the GND terminal.
5) The differential signal at the oscilloscope should be
between 100mVp-p and 150mVp-p.
Detailed Description
The MAX3665 is designed to accept a DC-coupled
input from a photodiode with an amplitude up to 450碌A(chǔ)
peak-to-peak. Because the MAX3665 provides a DC
bias for the photodiode, it cannot be DC-coupled to sig-
nal sources. To allow characterization without a photodi-
ode, the MAX3665 EV kit provides a simple circuit that
emulates a photodiode using common voltage output
signal sources.
