Semtech NT24L73

1.25Gbps CML Limiting Amplifier (MSOP)

Add to Watch List

The NT24L73 is a CMOS limiting post amplifier for fiber optic transceiver applications. The NT24L73 features CML outputs that are intended to be AC coupled to the proceeding circuitry. Powered from a +3.3 V power supply the NT24L73 represents the lowest cost and lowest power limiting amplifier solution for optical network applications at data rates up to 1.25 Gbps. The NT24L73 incorporates a data output squelch function, a glitchFree SD function with tunable detection threshold.


  • Fabricated in high volume, pure CMOS process for lowest cost
  • Single +3.0 V to +5.5 V supply voltage
  • CML data output stage
  • Typically 17 mA supply current
  • glitchFree signal status output
  • CMOS LOS status output
  • Data outputs squelch function
  • Adjustable LOS threshold
  • M SOP 10-pin RoHS package
  • Pin compatible with Micrel SY88993V and Maxim MAX3747 Limiting Amplifiers


  • GbE/OC-12


  • MSOP 8
