Texas Instruments LX21EVK01 Evaluation Kit LX21EVK01/NOPB LX21EVK01/NOPB Datenbogen

 

     

  

 

       Rev 1.0 

 

 
The LX21EVK01 is designed to allow for easy evaluation of the DS92LX2121 and DS92LX2122 Channel Link III Ser/Des. This 
kit allows for 2 basic methods of evaluation:  
 

1)  Users may apply parallel clock, data and I2C commands, and evaluate the power, jitter and cable performance of the 

Ser/Des. Or, 
 

2)  Apply only a parallel clock and enable BIST mode. This allows the user to easily evaluate the serial link and check 

device feature functionality such as receive equalization, SSCG, etc. 
 

The LX16EVK01 boards uses USB connectors as the serial Channel Link III inputs/outputs. SMA connectors can also be 
attached and configured for serial input/output if other types of the cable are desired.
