________________Detailed Description
The MAX3665 is a transimpedance amplifier designed
for 622Mbps SDH/SONET applications. It comprises a
transimpedance amplifier, a paraphase amplifier with
CML differential outputs, and a DC cancellation loop.
Figure 1 shows a functional diagram of the MAX3665.
Transimpedance Amplifier
The signal current at IN flows into the summing node of a
high-gain amplifier. Shunt feedback through R
F
converts
this current to a voltage. Diodes D1 and D2 clamp the
output voltage for large input currents.
