The TAT6254B integrates two low noise, high gain trans-impedance amplifiers in a differential configuration followed by an output amplifier. It provides a low input impedance to minimize the effects of photodiode capacitances and stray impedance affects on gain flatness. The TAT6254B was designed as a general purpose FTTP receiver, and allows wide flexibility in setting gain, tilt, and bias levels. Gain control is accommodated with a low cost external PIN diode circuit placed between the input trans-impedance amplifier and the output amplifier.
