GENERAL DESCRIPTION
The TDA8722 is a programmable modulator which
generates an RF TV channel from a baseband video
signal and a baseband audio signal in the event of
negative video and FM sound standards (PAL B/G, I, D/K
and NTSC).
It is especially suited for satellite receivers, video
recorders and cable converters. The video carrier
frequency is set exactly to the correct channel frequency
by a PLL synthesizer which is programmed in accordance
with the I
