NOTE: CEQ is 1 pF to 3 pF and is the equivalent input capacitance of the clock buffer.

Figure 148. Internal Clock Buffer

A single-ended CMOS clock may be ac-coupled to the CLKP input, with CLKM connected to ground with a

0.1-μF capacitor, as shown in Figure 149. However, for best performance the clock inputs must be driven

differentially, thereby reducing susceptibility to common-mode noise. For high input frequency sampling, TI

recommends using a clock source with low jitter. Band-pass filtering of the clock source may help reduce the

effects of jitter. There is no change in performance with a non-50% duty cycle clock input.
