(VHS standard)

TDA9725

CHARACTERISTICS

VCC =5V; Tamb = +25 °C and typical application (see Figs 1 and 2), unless otherwise speciﬁed.

Luminance part: All amplitudes are VBS peak-to-peak values, unless otherwise speciﬁed.

Chrominance part: All amplitudes for PAL and NTSC are red values with 75% saturation and chrominance-to-burst ratio

of 2.2 : 1, unless otherwise speciﬁed.
