TDA9115

13/45

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.
