iT3011
12.5 Gb/s High-Sensitivity Limiter Amplifier
Description
The iT3011 is a limiting amplifier for use as a post amplifier in OC-192 and STM-64 optical
receivers. Signals as small as +/-7 mVpp differential can be amplified to 1.28 Vpp differential.
Offset correction and output voltage control are provided. Both AC and DC coupling are allowed
at the input and output. The high sensitivity allows the device to be used at the output of a
transimpedance amplifier.
