TDA8366
FEATURES
·
Multistandard vision IF circuit (positive and
negative modulation)
·
Video identification circuit in the IF circuit which is
independent of the synchronization for stable On Screen
Display (OSD) under ‘no-signal’ conditions
·
Source selection with 2 Colour Video Blanking
Synchronization (CVBS) inputs and a Y/C (or extra
CVBS) input
GENERAL DESCRIPTION
The TDA8366 is an I 2 C-bus controlled PAL/NTSC TV
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 2 C-bus.
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.
·
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
·
PAL/NTSC colour decoder with automatic search
system
·
Easy interfacing with the TDA8395 (SECAM decoder)
for multistandard applications
·
RGB control circuit with black-current stabilization and
white point adjustment; to obtain a good grey scale
tracking the black-current ratio of the 3 guns depends on
the white point adjustment
·
Linear RGB inputs and fast blanking
·
Horizontal synchronization with two control loops and
alignment-free horizontal oscillator
·
Vertical count-down circuit
·
Geometry correction by means of modulation of the
vertical and EW drive
·
I 2 C-bus control of various functions
·
Low dissipation (850 mW)
·
Small amount of peripheral components compared with
competition ICs
·
Only one adjustment (vision IF demodulator)
·
Y, U and V inputs and outputs.
