Source selection with 2 Colour Video Blanking
Synchronization (CVBS) inputs and a Y/C (or extra
CVBS) input
Output signals of the video switch circuit for the teletext
decoder and a Picture-In-Picture (PIP) processor
Integrated chrominance trap and bandpass filters
(automatically calibrated)
Integrated luminance delay line
Asymmetrical peaking in the luminance channel with a
(defeatable) noise coring function

GENERAL DESCRIPTION
The TDA8366 is an I
processor. The circuit has been designed for use with the
baseband chrominance delay line TDA4665 and for
DC-coupled vertical and East-West (EW) output stages.
The device can process both CVBS and Y/C input signals
and has a linear RGB-input with fast blanking.
The peaking circuit generates asymmetrical overshoots
(the amplitude of the ‘black’ overshoots is approximately
2 times higher as the one of the ‘white’ overshoots) and
contains a (defeatable) coring function.
The RGB control circuit contains a black-current stabilizer
circuit with internal clamp capacitors. The white point of the
picture tube is adjusted via the I
The deflection control circuit provides a drive pulse for the
horizontal output stage, a differential sawtooth current for
the vertical output stage and an East-West drive current for
the East-West output stage.These signals can be
manipulated for geometry correction of the picture.
The supply voltage for the IC is 8 V. The IC is available in
an SDIP package with 52 pins and in a QFP package with
64 pins (see Chapter “Ordering information”).
The pin numbers indicated in this document are
referenced to the SDIP52; SOT247-1 package; unless
otherwise indicated.
