    Thread Summary
    
                The user inquired about using one AD2S99 generator with four AD2S90 ICs for position sensing. The final answer stated that this setup is not advisable due to the phase detect logic circuitry and the requirement for a local oscillator in each RDC. The AD2S1210 RDC with an integrated reference oscillator was suggested as an alternative. The user noted that minimizing part count is a priority for reliability.

    Hello.
    
 
    Is it possible to use one generator AD2S99 with buffer and four AD2S90 IC's?
    
 
    What to do with pins of AD2S99 SIN COS SYNREF? 
    
 
    Maybe there are some detailed shematics like in figure 16 of datasheet AD2S90 http://www.analog.com/media/en/technical-documentation/data-sheets/AD2S90.pdf  
    
 
    What accuracy should we expect?
    
 
    Velocity not interested, only position.
