MG2155 is a CMOS TIA with wide input dynamic range, high optical sensitivity (-38dBm with PIN) and high overload tolerance (2mApp). Automatic gain control (AGC) circuit is implemented in order to achieve such wide dynamic range. In addition to automatically reducing TIA gain, this AGC circuit also helps to maintain integrity of input signal with excellent transimpedance linearity over frequency. A current sourcing monitor of average photodiode current is available at MON pad for receiver power monitoring for PIN photodiodes.
