TV signal processor-Teletext decoder
with embedded µ-Controller
Tentative Device Specification
TDA955X/6X/8X H/N1 series
GENERAL DESCRIPTION
The various versions of the TDA955X/6X/8X H/N1 series
combine the functions of a video processor together with a
µ-Controller and US Closed Caption decoder. Most
versions have a Teletext decoder on board. The Teletext
decoder has an internal RAM memory for 1or 10 page text.
The ICs are intended to be used in economy television
www.DataShereet4cUei.vcoemrs with 90° and 110° picture tubes.
The ICs have supply voltages of 8 V and 3.3 V and they
are mounted in a QFP 80 envelope.
The features are given in the following feature list. The
differences between the various ICs are given in the table
on page 4.
FEATURES
TV-signal processor
Multi-standard vision IF circuit with alignment-free PLL
demodulator
Internal (switchable) time-constant for the IF-AGC circuit
The QSS and mono FM functionality are both available
so that an FM/AM TV receiver can be built without the
use of additional ICs
The mono intercarrier sound circuit has a selective
FM-PLL demodulator which can be switched to the
different FM sound frequencies (4.5/5.5/6.0/6.5 MHz).
The quality of this system is such that the external
band-pass filters can be omitted.
The FM-PLL demodulator can be set to centre
frequencies of 4.74/5.74 MHz so that a second sound
channel can be demodulated. In such an application it is
necessary that an external bandpass filter is inserted.
The vision IF and mono intercarrier sound circuit can be
used for the demodulation of FM radio signals
Video switch with 2 external CVBS inputs and a CVBS
output. One of the CVBS inputs can be used as Y/C
input.
2 external audio inputs. The selection of the various
inputs is coupled to the selection of the CVBS signals
Integrated chrominance trap circuit
Integrated luminance delay line with adjustable delay
time
Switchable group delay correction in the CVBS path
Picture improvement features with peaking (with
switchable centre frequency, depeaking, variable
positive/negative overshoot ratio and video dependent
coring), dynamic skin tone control and blue-, black- and
white stretching
Integrated chroma band-pass filter with switchable
centre frequency
Switchable DC transfer ratio for the luminance signal
Only one reference (12 MHz) crystal required for the
µ-Controller, Teletext- and the colour decoder
PAL/NTSC or multi-standard colour decoder with
automatic search system
Internal base-band delay line
Indication of the Signal-to-Noise ratio of the incoming
CVBS signal
A linear RGB/YUV/YPBPR input with fast blanking for
external RGB/YUV sources. The synchronisation circuit
can be connected to the incoming Y signal. The
Text/OSD signals are internally supplied from the
µ-Controller/Teletext decoder.
RGB control circuit with ‘Continuous Cathode
Calibration’, white point and black level off-set
adjustment so that the colour temperature of the dark
and the light parts of the screen can be chosen
independently.
Contrast reduction possibility during mixed-mode of
OSD and Text signals
Adjustable ‘wide blanking’ of the RGB outputs
Horizontal synchronization with two control loops and
alignment-free horizontal oscillator
Vertical count-down circuit
Vertical driver optimized for DC-coupled vertical output
stages
Horizontal and vertical geometry processing
Horizontal and vertical zoom function for 16 : 9
applications
Horizontal parallelogram and bow correction for large
screen picture tubes
Low-power start-up of the horizontal drive circuit
