Product Details

The ADN2821 is a 10 Gbps high-performance SiGe Transimpedance Amplifier specifically designed for use in small form factor optical receivers. The ADN2821 series features low input referred noise current and a range of trans-impedance gains. 8GHz minimum bandwidth enables up to 11.1 Gbps operation; 1.1uA input referred noise current enables –19dBm sensitivity; +3.25dBm nominal operation at 10dB extinction ratio. For assembly in small form factor packages, the ADN2821 series integrates a photodiode filter RFCF network on-chip and features 25kHz low frequency cutoff with small 0.5nF external capacitor. The ADN2821 operates with a 3.3V ± 0.3V power supply and is available in die form.

Applications

  • Up to 11.1 Gbps Optical Modules
  • SONET/SDH OC-192/STM-64 and 10 GbE Receivers, Transceivers, Transponders
