    Hello
    
 
    Please find attach Schematic diagram and Vector file.
    
 
    I tried to test AD8370 and applied a vector(Pattern) as attach.
    
 
    I am not getting a desire result at output pin 8 & 9.
    
 
    Anyone can share the example vector file to test this device or either evaluate my vector file.
    
 
    I have written the vector for Gain code HG45 and applied  200mVp-p sine wave to INLO pin of AD8370.
    
 
    Best Regards
    
 
    Nikhil

      Hi Nikhil,
      
 
      Unfortunately, there isn't a good way for us to look at your vector pattern.Can you send a oscope plot of the DATA, CLKK and LTCH pins? This would help to validate timing.
      
 
      For the schematic, I am not clear on the AD9433 input clock. Where is the clock coming from? And have you looked to see a valid clock is at the ADC pin?
      
 
      Regards,
