Product
Transimpedance / Switched Integrator
The MAX3654 evaluation kit (EV kit) is a factory-
assembled printed circuit board (PCB) that provides two
circuit versions—optical input and electrical input.
The optical circuit includes the photodiode bias circuitry,
an op amp for feed-forward AGC operation, and a balun
for single-ended 75Ω output. Through-hole pads are
provided to attach a triplexer analog photodiode. It is
important to select a photodiode with capacitance and
inductance in the anode and cathode connections as
symmetric as possible for optimum linearity.
The electrical circuit is normally configured with a 50Ω
input for use with conventional test and measurement
equipment and a 75Ω output. The 75Ω output can be
connected to 50Ω test and measurement equipment using
a minimum loss pad. If desired, the MAX3654 input can
also provide a 75Ω input by replacing R12 and R13 with
25Ω resistors.
