Semtech GN1057

10/11.3 Gb/s Transimpedance Amplifier with Automatic Gain Control

Gennum's GN1057 is a fully integrated silicon germanium (SiGe) BiCMOS transimpedance amplifier, providing wideband low noise pre-amplification of a current signal from a PIN photodiode or APD.

It features differential outputs and incorporates automatic gain control (AGC) to improve linear dynamic range. A decoupling capacitor on the supply is the only external component required.

Features


  • Single +3.3V power supply
  • Power dissipation 190mW (typical)
  • Bandwidth remains constant over dynamic range
  • Typical small signal gain of 4 kΩ
  • RSSI (Receive Signal Strength Indicator)
  • Operates from 9.95Gb/s to 11.3 Gb/s NRZ

Applications


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