13.0 Typical Performance Characteristics
13.1 CLOCK OUTPUT AC CHARACTERISTICS
Note 39: To estimate this noise, only the output frequency is required. Divide value and input frequency are not relevant.
Note 40: The noise of the delay block is independent of output type and only applies if the delay is enabled. The noise floor, due to the distribution section
accounting for the delay noise, can be calculated as: Total Output Noise = 10 x log(10
