Notes:
1. Represents stress ratings only, and functional operation at the maximums is not guaranteed.
2. Gives the nominal values of the external components and their maximum acceptable tolerance, assuming ZCH = 28.
3. Do not populate CF. Leave pads for future use.
4. Multiple Supplies: The voltage on any input or I/O pin cannot exceed the power pin during power-up. Power supply sequencing is NOT required.
5. Refclk jitter measured at VDDIR (nom)/2.
6. If input modulation is used: input modulation is allowed but not required.
7. Capacitance measured at Freq=1 MHz, DC bias = 0.9V and VAC < 100 mV.
8. 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%.
