8.3.2 Clock Inputs

The ADS54T01 clock input can be driven differentially with a sine wave, LVPECL, or LVDS source with little or no difference in performance. The common-mode voltage of the clock input is set to 0.9 V using internal 2-kΩ resistors. This allows for AC coupling of the clock inputs. The termination resistors should be placed as close to the clock inputs as possible to minimize signal reflections and jitter degradation.
