GN1035

Overview

Gennum's GN1035 is a fully integrated, silicon germanium transimpedance amplifier; providing wideband, low noise pre-amplification of signal current from a photodetector.It features differential outputs, and incorporates an automatic gain control mechanism to increase dynamic range, allowing input signals up to 2.6 mA peak. A decoupling capacitor on the supply is the only external circuitry required.

Features/Highlights

  • Single +3.3V power supply
  • Power dissipation 125mW (typ)
  • Input noise current = 250nA rms when used with a 0.5pF detector
  • Transimpedance gain 10kΩ into 100Ω load (differential)
  • Bandwidth (-3dB) = 2.0GHz
  • No photodiode bypass capacitor required in PIN-based applications.
  • RSSI (received signal strength indicator) current output operates from sensitivity to overload, selectable source or sink
  • Bondpad configuration, and output polarity control, allow for maximum flexibility in pin-out in a TO Can ROSA
  • On-chip filter to improve sensitivity and control bandwidth
  • Key Applications

    • GPON ONU/ONT
    • Gigabit Ethernet
    • 2x Fibre Channel
  • PCI Express
  • SONET/SDH
  • Infiniband
