iT3018
12.5 Gb/s High-Gain RX Limiter Amplifier
Description
The iT3018 is a limiting amplifier for use as a post amplifier in OC-192 and STM-64
optical receivers. Differential signals as small as +/-6 mVpp can be amplified to 2.2 Vpp
differential. The device includes offset correction and output voltage control. Both AC and
DC coupling are allowed at both input and output. The high sensitivity of the iT3018
allows the device to be used at the output of a transimpedance amplifier.
