NOTES:
42. Guaranteed by design or characterization.
43. Test performed with CL = 40pF, IOL = 4mA, IOH = -4mA. Input reference level is 1.5V for all inputs. VIH = 3.0V, VIL = 0V.
44. Since the HMP8117 does not generate the sample clock, any clock jitter present on the CLK2 input will directly translate to pixel jitter on the
output data. The Vertical Sample Alignment parameter specifies the spatial pixel alignment from one scan line to the next using a stable CLK2
source.
