MAX3266/MAX3267 Evaluation Kits
General Description
The MAX3266 and MAX3267 evaluation kits (EV kits)
simplify evaluation of the MAX3266 and MAX3267
transimpedance preamplifiers.
The EV kits include a circuit that emulates the high-
speed, zero-to-peak current input signal that would be
produced by a photodiode. The kit also includes a cali-
bration circuit that allows accurate bandwidth measure-
ments.
The MAX3266 and MAX3267 EV kits are fully assem-
bled and tested.

Note: Please indicate that you are using the MAX3266/MAX3267
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 MAX3266 EV kit.)
The signal should have data rate between 500Mbps
and 1250Mbps.
2) Connect OUT+ and OUT- to the 50Ω inputs of a
high-speed oscilloscope.
3) Remove shunts from jumpers JU1 and JU2.
4) Connect a +3.3V supply to the VCC terminal and
ground to the GND terminal.
5) The differential signal at the oscilloscope should be
between 50mVp-p and 100mVp-p.
Detailed Description
The MAX3266 is designed to accept a DC-coupled
input from a high-speed photodiode, with an amplitude
of 10µA to 1mA zero-to-peak. Unfortunately, high-speed
current sources are not common laboratory equipment.
Also, because the MAX3266 provides a DC bias for the
photodiode, it cannot be DC coupled to signal sources.
