    Thread Summary
    
                The user tested the ADM3055E demo board and observed waveform deformation at data rates above 1 MHz. The final solution was to connect the RS pin to ground for high-speed operation, allowing successful testing up to 12 MHz. The user had initially set the RS pin with a 47K ohm resistor to GND and VIO shorted to VDD1.

    Hi SIr
    

    I tester EVAL-ADM3055E demo board to fount this chip TX pin data rate over 1MHz the second side output waveform was deformation ,if we need operation at 4MHz or more speed ,ADI have any suggestion?
    

    ADM3055E Second side TX port waveform (Data Rate:1MHz)
    

     
    

    ADM3055E Second side TX port  waveform (Data Rate:1.8MHz)
    

     
    

    ADM3055E Second side TX port  waveform (Data Rate:3MHz)
    

     
    

    Primary side signal generator setting (Vp-p:3.3V Duty:50% ,square wave)
    

     
    

    

    Best
    

    Jack
