The HXR14100 single channel linear Trans-Impedance Amplifier (TIA) is a member of Optical Receiver Transmitter Array (ORTA) product family. Together with a PIN detector, the HXR14100 can be used to design a compact linear ROSA for the next generation 200G optical transceivers with advanced modulation schemes in 28GBaud PAM4 data rates.

This TIA operates in a 3.3V supply or in a 2.9V supply for low power consumption, providing exceptionally low input referred noise density, wide input optical power range, excellent linearity up to 3mA overload, and a high bandwidth. The chip is designed with the patented adaptive biasing scheme.  


  • High receiver sensitivity for 56Gbps PAM4 Ethernet applications
  • Low power mode in 28Gbaud applications 
  • Power consumption as low as 140 mW/ch 
  • Industrial operating temperature range -40 to 95°C
  • Up to 5kΩ typical differential gain
  • Wide adjustable output voltage swing
  • Linear operation up to 3mAppSE overload with internal AGC
  • Up to 30GHz typical bandwidth
  • 9pA/√Hz input referred current noise density
  • RSSI, LOS and Rx disable functions  
  • IEEE 802.3 compliance
