Note 19:
KEYST at medium (neutral) value.
Note 20:
PCC at minimum value.
Note 21:
VPOS at medium (neutral) value.
Note 22:
HSIZE at minimum value.
Note 23: Defined as difference of (voltage at tVR=0) minus (voltage at tVR=1/2 TVR).
Note 24: Defined as difference of (voltage at tVR=TVR) minus (voltage at tVR=1/2 TVR).
Note 25:
VSIZE at maximum value.
Note 26: Difference: (voltage at tVR=0) minus (voltage at tVR=TVR).
Note 27: Ratio "A/B"of parabola component voltage at tVR=0 versus parabola component voltage at tVR=TVR.
See Figure 2.
Note 28: VHEHT>VRefO, VVEHT>VRefO
Note 29: VEW-AC is the sum of all components other than VEW-DC (contribution of PCC and keystone correction).
Note 30: More precisely tracking with voltage on HPLL1F pin which itself depends on frequency at a rate given by
external components on PLL1 pins. VEW[fmax] is the value at condition VHO>VHOThrfr.
