Semtech NT24L50

GbE/EPON/1.25Gbps TIA

Add to Watch List

The NT24L50 is a high sensitivity transimpedance amplifier (TIA) with automatic gain control (AGC) manufactured in CMOS. The AGC enables over 34 dB of dynamic operating range, resulting in a high performance TIA designed for cost sensitive fiber optic applications such as EPON transceivers, Gigabit Ethernet and Fiber Channel.


  • Typical -31 dBm sensitivity, +3 dBm overload at 1.25 Gbps when used with 0.9 A/W PIN (CPD = 0.65 pF, BER = 10-10)
  • Typical transimpedance: 27 k?
  • Manufactured in low cost, pure CMOS process
  • Single +3.3 V power supply
  • Differential data outputs
  • Internal regulated photodiode bias
  • No internal ROSA VDD supply decoupling capacitor required for typical operation
  • Photodiode current monitor output - can be programmed to Sink or Source
  • Data polarity invert function
  • Pad compatible drop-in replacement for Mindspeed M02016


  • GbE/EPON


  • Bare Die
