DAC1 Interface Jitter Tolerance
The graph above shows the results of a standard AES jitter tolerance test.
The top (red) curve shows the amplitude of the jitter applied to the inputs of the DAC1. The scale for the top
curve is on the right hand side of the graph and is calibrated in UI of jitter.
The bottom (green) curve shows the THD+N of the DAC1 as the jitter amplitude and frequency is varied at the
inputs of the DAC1. There is absolutely no change in the DAC1 THD+N measurement over the entire range of
jitter test frequencies and amplitudes. In fact, the DAC1 can tolerate much higher levels of jitter without any
measurable change in performance (see the next graph).
