4.VIDEO SWITCH TEA6415
In case of three or more external sources are used, the video switch IC TEA6415 is used. The main
function of this device is to switch 8 video-input sources on the 6 outputs.
Each output can be switched on only one of each input. On each input an alignment of the lowest level
of the signal is made (bottom of sync. top for CVBS or black level for RGB signals).
Each nominal gain between any input and output is 6.5dB.For D2MAC or Chroma signal the alignment
is switched off by forcing, with an external resistor bridge, 5VDC on the input. Each input can be used
as a normal input or as a MAC or Chroma input (with external Resistor Bridge). All the switching
possibilities are changed through the BUS. Driving 75ohm load needs an external resistor. It is possible
to have the same input connected to several outputs.
5.MULTI STANDARD SOUND PROCESSOR
The MSP 34x10G family of single-chip Multi-standard Sound Processors covers the sound processing
of all analog TV-Standards worldwide, as well as the NICAM digital sound standards. The full TV sound
processing, starting with analog sound IF signal-in, down to processed analog AF-out, is performed on
a single chip.
The DBX noise reduction, or alternatively, MICRONAS Noise Reduction (MNR) is performed alignment
free. Other processed standards are the Japanese FM-FM multiplex standard (EIA-J) and the FM
Stereo Radio standard.
6.SOUND OUTPUT STAGE WITH TDA7269A
The TDA7269A is class AB dual Audio power amplifier assembled in the Multi-watt package, specially
designed for high quality sound application as Hi-Fi music centers and stereo TV sets.
7.BERTICAL OUTPUT STAGE WITH STV9379FA
The IC STV9379FA is the vertical deflection booster circuit. Two supply voltages, +14V and –14V are
needed to scan the inputs VERT+ and VERT-, respectively. And a third supply voltage, +60V for the
flyback limiting are needed. The vertical deflection coil is connected in series between the output and
feedback to the input.
8.VIDEO OUTPUT AMPLIFIER TDA6108
The TDA6108Q includes three video output amplifiers is intended to drive the three cathodes of a
colour picture tube.

AK45 Service Manual 01/12/2003
9.POWER SUPPLY (SMPS)
The DC voltages required at various parts of the chassis are provided by an SMPS transformer
controlled by the IC MC44608, which is designed for driving, controlling and protecting switching
transistor of SMPS. The transformer generates 145V for FBT input, +/-14V for audio amplifier, 5V and
3.3V stand by voltage and 8V, 12V and 5V supplies for other different parts of the chassis.
An optocoupler is used to control the regulation of line voltage and stand-by power consumption. There
is a regulation circuit in secondary side. This circuit produces a control voltage according to the
changes in 145V DC voltage, via an optocoupler (TCET1102G) to pin3 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.

13.3.MSP34X0G (MSP3410G)
13.3.1.Description
The MSP 34x0G family of single-chip Multi standard Sound Processors covers the sound processing of
all analog TV-Standards worldwide, as well as the NICAM digital sound standards. The full TV sound
processing, starting with analog sound IF signal-in, down to processed analog AF-out, is performed on
a single chip. Figure shows a simplified functional block diagram of the MSP 34x0G.
This new generation of TV sound processing ICs now includes versions for processing the multi
channel television sound (MTS) signal conforming to the standard recommended by the Broadcast
Television Systems Committee (BTSC). The DBX noise reduction, or alternatively, MICRONAS Noise
Reduction (MNR) is performed alignment free. Other processed standards are the Japanese FM-FM
multiplex standard (EIA-J) and the FM Stereo Radio standard. Current ICs have to perform adjustment
procedures in order to achieve good stereo separation for BTSC and EIA-J. The MSP 34x0G has
optimum stereo performance without any adjustments.
All MSP 34x0G versions are pin and software downward compatible to the MSP34x0D. The MSP34x0G
further simplifies controlling software. Standard selection requires a single I
2
C transmission only.
The MSP 34x0G has built-in automatic functions: The IC is able to detect the actual sound standard
automatically (Automatic Standard Detection). Furthermore, pilot levels and identification signals can be
evaluated internally with subsequent switching between mono/stereo/bilingual; no I
2
C interaction is
necessary (Automatic Sound Selection).

13.5.TEA6415C
13.5.1.General Description
The main function of the IC is to switch 8 video input sources on 6 outputs. Each output can be
switched on only one of each input. On each input an alignment of the lowest level of the signal is made
(bottom of synch. top for CVBS or black level for RGB signals). Each nominal gain between any input
and output is 6.5dB. For D2MAC or Chroma signal the alignment is switched off by forcing, with an
external resistor bridge, 5 V
DC on the input. Each input can be used as a normal input or as a MAC or
Chroma input (with external resistor bridge). All the switching possibilities are changed through the
BUS. Driving 75 load needs an external transistor. It is possible to have the same input connected to
several outputs. The starting configuration upon power on (power supply: 0 to 10V) is undetermined. In
this case, 6 words of 16 bits are necessary to determine one configuration. In other case, 1 word of 16
bits is necessary to determine one configuration.
13.5.2.Features
• 20MHz Bandwidth
• Cascadable with another TEA6415C (Internal address can be changed by pin 7 voltage)
• 8 Inputs (CVBS, RGB, MAC, CHROMA,...)
• 6 Outputs
• Possibility of MAC or chroma signal for each input by switching-off the clamp with an external resistor
bridge

The L7800 series of three-terminal positive regulators is available in TO-220 TO-220FP TO-3 and D 2
PAK packages and several fixed output voltages, making it useful in a wide range of applications.
These regulators can provide local on-card regulation, eliminating the distribution problems associated
with single point regulation. Each type employs internal current limiting, thermal shutdown and safe
area protection, making it essentially indestructible. If adequate heat sinking is provided, they can
deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices
can be used with external components to obtain adjustable voltages and currents.
