Notes 9. Jitter measured at crossing points and is the absolute value of the worst case deviation. 10. Measured at crossing points. 11. If input modulation is used; input modulation is allowed but not required. 12. The amount of allowed spreading for any non-triangular modulation is determined by the induced downstream tracking skew that cannot exceed the skew generated by the specified 0.6% triangular modulation. Typically, the amount of allowed non-triangular modulation is about 0.5%. 13. VOX
