1. INTRODUCTION
17MB24 Main Board consists of two major blocks. The first block is analog front-end
and this block is handled by VCTI chip that is highly multifunctional. This IC does
demodulation of Video & Audio from Tuner IF, CVBS, Audio, RGB, SVHS input
selection and processing. It has an audio processor that supports equalizer or tone
control, volume control, AVL, surround effect etc and supplies amplifier, headphone and
CVBS & audio line outputs. It handles video processing such as colour standard
detection and demodulation, picture alignment (brightness, contrast, colour etc.). The IC
also does teletext decoding with fastext memory. After video processing, the processed
video is applied to MST5*7a-M chip in RGB format.
The TV Tuner is an asymmetrical or a symmetrical IF output type and is PLL controlled.
The IF signal is applied single saw filter. After the SAW filter block, IF signal is applied to
VCTI IF inputs (Pin 16 and 17).
As VCTI can handle all the audio processing, there is no need for additional audio
processor solution on the board. VCTI supports three Audio outputs. These outputs are
assigned to Headphone, Speaker and I2C Controlled audio switch. The board employs
TDA1905 and TDA1308 to drive speaker and headphone outputs respectively.
The Back End section is handled by MST chip. The RGB input can handle standard
interlaced RGB output from VCTI, PC VGA RGB input and YPbPr. There are two set of
ADC is present in MST so YPbPr and VGA sources should be multiplexed.
MST chip have an integrated LVDS transmitter and this LVDS transmitter can be
activated or deactivated by registers so output of MST chip can be LVDS or TTL format.
Backlight is controlled via MST chip there are two pins to control inverter one of them is
used for adjusting backlight the other one is used for backlight on/off control.
2. TUNER
As the thickness of the TV set has a limit, a horizontal mounted tuner is used in the
product, which is suitable for CCIR systems B/G, H, L/ L’, I/I’, and D/K. The tuning is
available through the digitally controlled I2C bus (PLL). Below you will find info on the
Tuner in use.

10.4. MP1593
10.4.1. General Description
The MP1593 is a step-down regulator with an internal Power MOSFET. It achieves 3A
continuous output current over a wide input supply range with excellent load and line
regulation. Current mode operation provides fast transient response and eases loop
stabilization. Fault condition protection includes cycle-by-cycle current limiting and
thermal shutdown. Adjustable soft-start reduces the stress on the input source at turnon. In shutdown mode the regulator draws 20μA of supply current. The MP1593
requires a minimum number of readily available external components to complete a 3A
step down DC to DC converter solution.

10.4.6. Pin Functions
Pin1:BS
High-Side Gate Drive Boost Input. BS supplies the drive for the high-side N-Channel
MOSFET switch. Connect a 10nF or greater capacitor from SW to BS to power the high
side switch.
Pin2:IN
Power Input. IN supplies the power to the IC, as well as the step-down converter
switches. Drive IN with a 4.75V to 28V power source. Bypass IN to GND with a suitably
large capacitor to eliminate noise on the input to the IC.
Pin3:SW
21
Page 23
Power Switching Output. SW is the switching node that supplies power to the output.
Connect the output LC filter from SW to the output load. Note that a capacitor is required
from SW to BS to power the high-side switch
Pin4:GND
Ground.
Pin5:FB
Feedback Input. FB senses the output voltage to regulate that voltage. Drive FB with a
resistive voltage divider from the output voltage. The feedback threshold is 1.222V.
Pin6:COMP
Compensation Node. COMP is used to compensate the regulation control loop. Connect
a series RC network from COMP to GND to compensate the regulation control loop. In
some cases, an additional capacitor from COMP to GND is required.
Pin7:EN
Enable Input. EN is a digital input that turns the regulator on or off. Drive EN high to turn
on the regulator, drive EN low to turn it off. An Under Voltage Lockout (UVLO) function
can be implemented by the addition of a resistor divider from VIN to GND. For complete
low current shutdown its needs to be less than 0.7V. For automatic startup, leave EN
unconnected.
Pin8:SS
Soft-Start Control Input. SS controls the soft-start period. Connect a capacitor from SS
to GND to set the soft-start period. A 0.1μF capacitor sets the soft-start period to 10ms.
To disable the soft-start feature, leave SS unconnected.

10.5. IRF7314-IRF7316
Fifth Generation HEXFETs from International Rectifier utilize advanced processing
techniques to achieve extremely low on-resistance per silicon area. This benefit,
combined with the fast switching speed and ruggedized device design that HEXFET
Power MOSFETs are well known for, provides the designer with an extremely efficient
and reliable device for use in a wide variety of applications. The SO-8 has been
modified through a customized leadframe for enhanced thermal characteristics and
multiple-die capability making it ideal in a variety of power applications. With these
improvements, multiple devices can be used in an application with dramatically reduced
board space. The package is designed for vapor phase, infra red, or wave soldering
techniques.

10.7. 74HCT4053
10.7.1. General Description
The 74HC/HCT4053 are high-speed Si-gate CMOS devices and are pin compatible with
the “4053” of the “4000B” series. They are specified in compliance with JEDEC standard
no. 7A.
The 74HC/HCT4053 are triple 2-channel analog multiplexers/demultiplexers with a
common enable input (E). Each multiplexer/demultiplexer has two independent
inputs/outputs (nY0 and nY1), a common input/output (nZ) and three digital select inputs
(S1 to S3).
With E LOW, one of the two switches is selected (low impedance ON-state) by S1 to S3.
With E HIGH, all switches are in the high impedance OFF-state, independent of S1 to
S3.
VCC and GND are the supply voltage pins for the digital control inputs (S1, to S3, and
E). The VCC to GND ranges are 2.0 to 10.0 V for HC and 4.5 to 5.5 V for HCT. The
analog inputs/outputs (nY0 and nY1, and nZ) can swing between VCC as a positive limit
and VEE as a negative limit. VCC - VEE may not exceed 10.0 V.
For operation as a digital multiplexer/demultiplexer, VEE is connected to GND (typically
ground).
10.7.2. Features
●Low “ON” resistance:
