Note 19:
KEYST at medium (neutral) value.
Note 20:
TCC at medium (neutral) value.
Note 21:
BCC at medium (neutral) value.
Note 22:
PCC at minimum value.
Note 23:
VPOS at medium (neutral) value.
Note 24:
HSIZE at minimum value.
Note 25: Defined as difference of (voltage at tVR=0) minus (voltage at tVR=1/2 TVR).
Note 26: Defined as difference of (voltage at tVR=TVR) minus (voltage at tVR=1/2 TVR).
Note 27:
VSIZE at maximum value.
Note 28: Difference (voltage at tVR=0) minus (voltage at tVR=TVR).
Note 29: Ratio "A/B"of parabola component voltage at tVR=0 versus parabola component voltage at tVR=TVR.
See Figure 2.
Note 30:
HEHT>VRefO, VEHT> VRefO
Note 31: VEW-AC is sum of all components other than VEW-DC (contribution of PCC, keystone correction and corner
corrections).
Note 32: 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.
