Product specification
TDA9725
CHARACTERISTICS
VCC = 5 V; 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.
