概览

Semtech’s GN1052CWA2 is a fully integrated silicon germanium BiCMOS transimpedance amplifier, providing wideband, low noise preamplification 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.

功能

  • Single +3.3V power supply
  • 功耗:180 mW(典型值)
  • 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 = 4kΩ into a 100Ω 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 11.3Gbps NRZ rates
  • Power supply rejection at 100kHz = 16dB
  • 针对 PIN 型光电二极管进行优化
  • Can be used with APD (0.4pF) at 10Gbps
  • RSSI(接收信号强度指示),电流输出 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

应用

  • SONET/SDH-based transmission systems, test equipment and modules
  • OC-192 fibre optic modules and line termination
  • 10 Gigabit Ethernet
  • 光纤通道
  • Serial data systems up to 11.3Gbps
