LST1162F

The LST1162F is a dual-channel, differential input differential output, linear transimpedance amplifier (TIA) for 400G and 600G coherent detection receivers for long haul and metro applications.

The LST1162F can operate in automatic gain control (AGC) mode and manual gain control (MGC) mode. It can adjust its trans-impedance from 65Ω to 5kΩ and delivers an output voltage of 200-700 mVppd in AGC mode. The LST1162/LST1162F supports a very wide input optical power range. It provides low noise, linear amplification for differential input current up to 3mApp. The LST1162/LST1162F has peaking control functions to adjust frequency response for optimization of PD and DSP combination; it also has an output peak detector monitor function.

The LST1162F operates from a +3.3V power supply, and available in die form.
