NOTES:
1. Refclk jitter measured at VDDI,R(nom)/2
2. Capacitance measured at Freq = 1MHz, DC bias = 0.9V, and VAC < 100mV
3. If the input modulation is used, input modulation is allowed but not required.
4. The amount of allowed spreading for any non-triangular modulation is determined by the induced downstream tracking skew, which cannot
exceed the skew generated by the specified 0.6% triangular modulation. Typically, the amount of allowed non-triangular modulation is about
0.5%.
