Philips TDA9353PS
Philips Semiconductors
TV signal processor-Teletext decoder
with embedded µ-Controller
GENERAL DESCRIPTION
The various versions of theTDA935X/6X/8X PS/N2 series
combine the functions of a TV signal 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
receivers with 90° and 110° picture tubes.
The ICs have supply voltages of 8 V and 3.3 V and they
are mounted in S-DIP envelope with 64 pins.
The features are given in the following feature list. The
differences between the various ICs are given in the table
on page 4.
Tentative Device Specification
TDA935X/6X/8X PS/N2 series
FEATURES
TV-signal processor
Multi-standard vision IF circuit with alignment-free PLL
demodulator
Internal (switchable) time-constant for the IF-AGC circuit
A choice can be made between versions with mono
intercarrier sound FM demodulator and versions with
QSS IF amplifier.
The mono intercarrier sound versions have 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.
Source selection between ‘internal’ CVBS and external
CVBS or Y/C signals
Integrated chrominance trap circuit
Integrated luminance delay line with adjustable delay
time
Picture improvement features with peaking (with
variable centre frequency and positive/negative
overshoot ratio) and black stretching
Integrated chroma band-pass filter with switchable
centre frequency
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
RGB control circuit with ‘Continuous Cathode
Calibration’, white point and black level offset
adjustment so that the colour temperature of the dark
and the light parts of the screen can be chosen
independently.
Linear RGB or YUV input with fast blanking for external
RGB/YUV sources. The Text/OSD signals are internally
supplied from the µ-Controller/Teletext decoder
Contrast reduction possibility during mixed-mode of
OSD and Text signals
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
