    cy29940/42/48 clock distribution product

    gil.vishinsky

      hey,

         

      i am using both cy29940 and cy29948 in two locations in my system. 

         

      i am trying to understand why the cy29948 output is a clean square wave while the output of the 29940 has a significant ripple (~0.4v of the 2.4vptp output). both are connected similarly with one output terminated with 50ohm (scope) and the rest are disconnected. 

         

      i would like to know if there is a difference in isolation between outputs in both products and if there is where can i aquire a 1:18 distributer with high output isolation (the cy29942 maybe?).

         

      thanks,

      p.s

         

      if nacessary i can produce a waveform of both and a schematic connection.
