iT3018E
12.5-Gb/s High-Gain RX Limiter Amplifier
Description
Features
www.DataSheet4U.com
The iT3018E is a RoHS-6-compliant 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 iT3018E allows the device to be used at the output of a transimpedance
amplifier.
¾ 3 dB bandwidth: 10 GHz
¾ Differential gain: 50 dB
¾ Saturated output: 1.1 Vpp, each output
into 50 ohms
¾ Input sensitivity 3.0 mVpp at BER<1E-12
¾ Single bias supply: -5.2 V
¾ Power consumption: 624 mW
¾ Bias current: 120 mA
¾ DC offset correction
¾ Amplitude voltage control
¾ Low RMS jitter
¾ RoHS-6-compliant 4x4 mm QFN (MO-220) package
