M02020

4 Gbps CMOS Transimpedance Amplifier with AGC


Overview

Description

The M02020 is a 4 Gbps transimpedance amplifier (TIA) achieving a wide input dynamic range to support different transmission distance requirements. Input overload of 4 mAPP is provided to support short-haul fiber optic systems and input sensitivity of better than -23 dBm is useful for single-mode tests of high power long haul links.

The M02020 incorporates an automatic gain control (AGC) in order to satisfy high sensitivity and optical overload requirements. The AGC monitors the output amplitude and automatically reduces the TIA gain when the photodiode current exceeds the AGC threshold, maintaining the output at a constant level.

Features

  • Typical -23 dBm Sensitivity
  • Data rates to 4.25 Gbps
  • No filter (PINK) capacitor required
  • AGC provides dynamic range of 29 dB
  • 3 kΩ differential transimpedance
  • 4 mAPP overload input current
  • Photodiode current monitor
  • Internal or external bias for photodiode
  • Single +3.3V supply
  • Same pad layout and die size as M02011/13/14/15/16/24/26
