Features and Applications

The SY88903ALKG TR is a 3.6 V 1 GHz burst mode, high-sensitivity limiting post amplifier is designed for use in fiber-optic receivers,specially optimized for passive optical networks (PONs). The device connects to typical transimpedance amplifiers (TIAs)

The linear signal output from TIAs can contain significant amounts of noise and may vary in amplitude over time.The SY88903AL quantizes these signals and outputs PECL level waveforms. The SY88903AL operates from a single +3.3 V power supply, over temperatures ranging from –40°C to +85°C


  • Single 3.3 V power supply
  • Fast LOS release/assert (<500ns) time for PON applications
  • 622 Mbps to 1.25 Gbps operation
  • Low-noise PECL data outputs
  • High gain LOS
  • TTL /EN input
  • Programmable LOS level set (LOSLVL)
  • Available in a tiny 10-pin MSOP package


  • Gigabit Ethernet, 1062 Mbps Fibre Channel
  • OC-12/24 SONET/SDH
  • Low-gain TIA interface
  • High-gain line driver and line receiver
