POWER SUPPLY (SMPS)

TDA16846

A SMPS transformer controlled by the IC TDA16846, which is designed for driving, controlling, and protecting switching
transistor, provides the DC voltages required at various parts of the chassis. SMPS generates the necessary 5V supply for
the micro-controller, 130V supply for the FBT, +/-16V supply for the audio amplifier, which are active in stand-by and others
8V, 12V and 5V for other different parts of the chassis.
When the TV is switched on, a reference voltage is provided to TDA16846 and the start-up operation occurs, then TV enters
into the stand-by position.
Two optocouplers are used to control the regulation of line voltage and stand-by power consumption. There are two regulation
circuits, one in primary side and one in secondary side. The primary regulation circuit provides a control voltage to pin3 of the
IC. Secondary regulation circuit produces a control voltage according to the changes in 130V DC voltage, via an optocoupler
(SFH617A) to pin4 of the IC.
During the switch on period of the transistor, energy is stored in the transformer. During the switch off period energy is fed to
the load via secondary winding. By varying switch-on time of the power transistor, it controls each portion of energy transferred
to the second side such that the output voltage remains nearly independent of load variations. At the same time, the supply
voltages 12V, 8V, 5V are stabilised by the series regulators.

IF PART

TDA4470 / TDA4472

The TDA44XX is an integrated bipolar circuit for multistandard video/sound IF (VIF/SIF) signal processing in TV/VCR and
multimedia applications. The circuit processes all TV video IF signals with negative modulation (e.g., B/G standard), positive
modulation (e.g., L standard) and the AM, FM/NICAM sound IF signals. Active carrier generation by FPLL (frequency phase­locked loop) is the principle for true synchronous demodulation. VCO circuit is operating on picture carrier frequency, the
VCO frequency is switchable for L´-mode. AFC without external reference circuit is alignment-free and polarity of the AFC
curve is switchable. VIF-AGC for negative modulated signals operates on peak sync detection principle and for positive
modulation on peak white / black level detection principle. Tuner AGC is adjustable with determining take over point. It has
alignment-free quasi-parallel sound (QPS) mixer for FM/NICAM sound IF signals. Intercarrier output sound is gain controlled
(necessary for digital sound processing). AM-demodulator is completely alignment-free with gain controlled AF output.
Operation of the AM demodulator and QPS mixer (for NICAM-L stereo sound is parallel. TDA4472 is used for negative

modulation and TDA4470 is used for both negative and positive modulation.

DIGITAL TV SOUND PROCESSING

MSP3410D

The MSP3410D is an I2C controlled single-chip multistandard sound processor for applications in analog and digital TV
sets. The full TV sound processing, starting with analog sound IF signal-in, down to processed analog AF-out is
performed in a single-chip covering all European TV-standards. It is designed to simultaneously perform digital
demodulation and decoding of NICAM-coded TV stereo sound, as well as demodulation of FM-mono TV sound and two
FM systems according to the German or Korean terrestrial specs. It is also possible to do AM-demodulation according to
the SECAM system. There is AGC for analog inputs: 0.14 - 3Vpp. All demodulation and filtering is performed on chip and
is individually programmable. All digital NICAM standards (B/G, L, and I) are realised. Only one crystal clock (18.432Mhz)
is necessary. External capacitors at each crystal pin to ground are required. They are necessary for tuning the open-loop
frequency of the internal PLL and for stabilising the frequency in closed-loop operation. The higher the capacitors, the
lower the clock frequency result. The nominal free running frequency should match the centre of the tolerance range
between 18.433 and 18.431Mhz as closely as possible. By means of standardised I2S interface, additional feature
processors (DPL35xx, Dolby Prologic processor for this chassis) can be connected to the IC.
I2S bus interface consists of five pins:
I2S_DA_IN12 for input four channels (two channels per line) per sampling cycle (32Khz).
I2DA_OUT, for output, two channels per sampling cycle (32KHz).
I2S_CL, for timing of the transmission of I2S serial data, 1.024Mhz.

MICROTEXT CONTROLLER

SDA30C264

The SDA30C264 is the microcontroller used with the Megatext IC. Its architecture and instruction set are based upon
that of the 8051 microcomputer. Like the 8051 it has many features which increase programming ease; extended internal
data memory-space, variable manipulation in internal data memory, free stack location in data RAM, 4 register banks,
special function registers, memory mapped I/O, individually addressable bits, and a Boolean processor which gives the
programmer the ability to improve the power of the software development. The IC produces the following input or output
control signals; AGC_CON, MODE_SW, L / L, PIP_MODS, PIP_SEL, ON/OFF (stand-by), SC1..3_IN_AV (pin 8
information from 3 SCARTs), AFC, MUTE (to mute audio output IC), I2CEN.

The SDA30C26x family, a derivative of the SAB C501, is a member of family of single-chip computers, in which the
emphasis is no longer placed on purely numeric computational performance, but on application-specific controller
functions.
Architecture and instruction set are based upon that of the 8051 microcomputer. Like the 8051 has many features which
increase programming ease; extended internal data memory-space, variable manipulation in internal data memory, free
stack location in data RAM, 4 register banks, special function registers, memory mapped I/O, individually addressable
bits and a Boolean processor give the programmer the ability to improve the power of software development. Numerical
problems can be processed with binary as well as with BCD-arithmetic. The many bit handling instructions also
contribute to the computers efficiency as a controller, Extended memory is controlled by an 8-bit data and a (16+3)-bit
address bus without any additional devices such as latches or logic elements, even when all 512K of the program
address space is used. All this leads, in suitable applications, to a reduction in the peripheral hardware and to a
simplification of the software and thus to reduced development and component costs. The controller, specially developed
for entertainment electronic applications, can also be recommended where both lowest component costs and a large
production volume are prime requirements.
The SDA 30C36x family members contain a 1024 + 256-byte or a 2048 + 256-byte data memory (XRAM + RAM), two
independent 16-bit timers /-counters and a seven-source, four-priority-level, nested interrupt structure, on-chip oscillator
and clock circuits. The 30 digital I/O-lines include four 8-bit ports (P1 and P3 contain I/O-lines with multifunction options)
and one 2-bit port. One or two serial interfaces are included, one behaves like the 8051 UART, the other is a I²C Bus
interface (SDA 30C264 only)
The second multifunction port consists of port P1, which alternatively can be used as up to eight independent pulse width
modulated output channels (PWM). Controlled via special function registers, the PWM-circuitry provides flexibility in time
resolution and system configuration.
Specially the realisation of D/A-outputs using pulse width modulation will be a cost saving advantage in analog
applications.

9

The internal ADC is an 8-bit, four-channel converter. The input channels are P20 to P23, the analog supply are pins VDDA
and VSSA. A flexible overvoltage / undervoltage detector is included (SDA 30C264 only).
Port 4 can be used as a standard port or as memory extension address bits.
Increased system reliability can be achieved by activating the integrated watchdog timer.
Efficient use of program memory results from an instruction set consisting of 49 single-byte, 46 two-byte and 16 three­byte instructions. Using an internal clock frequency of 12 MHz, 64 instructions execute in 0.5 us and 45b instructions
execute in 1.0us. The remaining instructions (multiple and devide) require only 2us. The number of bytes in each
instruction and the number of oscillator periods required for execution are listed in the instruction
Based on the SDA 30C163 and similar to the SDA 30C164, the SDA 30C26x comprise double stack size for the
extension memory (32 byte) and seven additional data pointer registers.
The SDA 30C263 is a reduced version of the SDA 30C264. The SDA 30C264 is functionally compatible to the
SDA 30C164, but uses a different package and a different Reset input stage (P-MQFP-80-1 instead of P-LCC-84).
If using the P-MQFP-64-1 Package, some I/O-features are not available.
