8.1.1 Input Clock Squarer

Figure 8-1 shows the input stage of the CDC3RL02. The input signal at MCLK_IN can be a square wave or sine wave. CMCLK is an internal AC coupling capacitor that allows a direct connection from the TCXO to the CDC3RL02 without an external capacitor.

CDC3RL02 Input Stage With Internal AC Coupling CapacitorFigure 8-1 Input Stage With Internal AC Coupling Capacitor

Any external component added in the series path of the clock signal potentially adds phase noise and jitter. The error source associated with the internal decoupling capacitor is included in the specification of the CDC3RL02. The recommended clock frequency band of the CDC3RL02 is 10MHz to 80MHz for specified functionality. All performance metrics are specified at 26MHz. The lowest acceptable sinusoidal signal amplitude is 0.8VPP for specified performance. Amplitudes as low as 0.3VPP are acceptable but with reduced phase-noise and jitter performance.
