NT22010 Low Cost 3.3 V Fast Ethernet Single-Chip Receiver IC with High-Sensitivity for applications over Plastic Optical Fiber

       
       
  Main Features   General Description
       

-29 dBm sensitivity, +4 dBm overload at 125 Mbps (BER 10-12 , 0.3 A/W PD).

 

The signal path of the NT22010 consists of a state-of-the-art, high sensitivity AGC (automatic gain control) trans-impedance amplifier followed by a Limiting Amplifier. Combined with an external Photodiode, a complete light-to-logic solution is provided.

In addition the NT22010 has a squelch mode and input-signal signal detect.

All passive components are integrated on-chip and the NT22010 is manufactured in a standard deep-sub-micron mixed signal CMOS process, giving an ultra low-cost, high performance and rugged solution.

     

Fabricated in standard high-volume mixed-signal CMOS process.

 
     

Less than 40 mA total current consumption.

 
     

Differential output with extended output swing.

 
     

3.3 V supply voltage.

 
     

High temperature operation (125 °C junction temperature).

 
     

No external components required within FOT.

 
     

Average Photocurrent monitor output available (IMON pad).

 
     
  Application  
     
Fast Ethernet
