... Figure 2 shows the typical bench characterization setup used to evaluate the ac performance of the AD9642, AD9634, or AD6672 critical that the signal sources used for the analog input and the clock have very low phase noise (<1 ps rms jitter) to realize the opti- mum performance of the signal chain ...

... R427 and R428 to enable Channel A and Channel B, respectively. Clock Circuitry The default clock input circuit that is populated on the AD9642/ AD9634/AD6672 coupled circuit with a high bandwidth 1:1 impedance ratio transformer (T503) that adds a very low amount of jitter to the clock path. The clock input is 50 Ω ...
