Semtech GN1052CW

10/11.3Gb/s Transimpedance Amplifier

Add to Watch List

Semtech’s GN1052CW is a fully integrated silicon germanium (Semtech) BiCMOS transimpedance amplifier, providing wideband, low noise preamplication of signal current from a PIN photodiode or APD. It features differential outputs. A decoupling capacitor on the supply is the only external component required.

Features


  • Single +3.3 V power supply
  • Power dissipation =180mW (typ)
  • Input Noise Density 10pA/√Hz
  • Input noise current = 1 μA rms when used with a 0.2pF detector and 1nH input bond wire
  • Transimpedance gain = 4k? into a 100? load (differential)
  • Input current overload = 2.6mA pk (+1.1dBm for 1A/W responsivity - meets 10 Gigabit Ethernet specification)
  • Upper Bandwidth (-3dB) = 13GHz
  • Lower Bandwidth (-3dB) = 24kHz
  • Operates at OC-192/STM-64 up to 11.3Gb/s NRZ rates
  • Power supply rejection at 100kHz = 16dB
  • Optimized for PIN photodiodes
  • Can be used with APD (0.4pF) at 10Gb/s
  • RSSI (Receive Signal Strength Indicator), current output operates from sensitivity to overload
  • Constant photodiode reverse bias voltage = 2V (anode to input, cathode to VCC)
  • Minimal external components, supply decoupling only
  • Operating junction temperature range = -40 to +125°C

Applications


  • SONET/SDH-based transmission systems, test equipment and modules
  • OC-192 fibre optic modules and line termination
  • 10 Gigabit Ethernet
  • Fibre Channel
  • Serial data systems up to 11.3Gb/s
