cy29940/42/48 clock distribution product
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?).
if nacessary i can produce a waveform of both and a schematic connection.
