4. MULTI STANDARD SOUND PROCESSOR
The MSP34x0G family of single-chip Multistandard Sound Processors covers the sound processing of
all analogue TV-Standards worldwide, as well as the NICAM digital sound standards. The full TV sound
processing, starting with analogue sound IF signal-in, down to processed analogue AF-out, is
performed on a single chip.
These TV sound processing ICs include versions for processing the multichannel 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 34x1G has optimum stereo performance without any adjustments.
5. 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.
6. AUDIO AMPLIFIER STAGE WITH TPA3004D2
The TPA3004D2 is a 12-W (per channel) efficient, Class-D audio amplifier for driving bridged-tied
stereo speakers. The TPA3004D2 can drive stereo speakers as low as 4 . The high efficiency of the
TPA3004D2 eliminates the need for external heatsinks when playing music.
Stereo speaker volume is controlled with a dc voltage applied to the volume control terminal offering a
range of gain from –40 dB to 36 dB. Line outputs, for driving external headphone amplifier inputs, are
also dc voltage controlled with a range of gain from –56 dB to 20 dB.
An integrated 5-V regulated supply is provided for powering an external headphone amplifier.

11. SAW FILTERS
K9656M:
Standard:
• B/G
• D/K
• I
• L/L’
Features
• TV IF audio filter with two channels
• Channel 1 (L’) with one pass band for sound carriers at 40.40 MHz (L’) and 39.75 MHz (L’- NICAM)
• Channel 2 (B/G, D/K, L, I) with one pass band for sound carriers between 32.35 MHz and 33.40 MHz
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.

The MSP 34x0G family of single-chip Multistandard 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 multichannel
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 MSP 34x0D. The MSP
34x0G further simplifies controlling software. Standard selection requires a single I²C 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 I²C interaction is
necessary (Automatic Sound Selection).

12.16. M29W040B
12.16.1. Description
The M29W040B is a 4Mbit (512Kb x8) non-volatile memory that can be read, erased and
reprogrammed. These operations can be performed using a single low voltage (2.7 to 3.6V) supply. On
power-up the memory defaults to its Read mode where it can be read in the same way as a ROM or
EPROM. The M29W040B is fully backward compatible with the M29W040.The memory is divided into
blocks that can be erased independently so it is possible to preserve valid data while old data is erased.
Each block can be protected independently to prevent accidental Program or Erase commands from
modifying the memory. Program and Erase commands are writ-ten to the Command Interface of the
memory. An on-chip Program/Erase Controller simplifies the process of programming or erasing the
memory by taking care of all of the special operations that are required to update the memory contents.
The end of a program or erase operation can be detected and any error conditions identified. The
command set required to control the memory is consistent with JEDEC standards. Chip Enable, Output
Enable and Write Enable signals control the bus operation of the memory. They allow simple
connection to most microprocessors, often without additional logic.

12.25. LM2576
12.25.1. General Description
The LM2576 series of regulators are monolithic integrated circuits ideally suited for easy and
convenient design of a step–down switching regulator (buck converter). All circuits of this series are
capable of driving a 3.0 A load with excellent line and load regulation.
These devices are available in fixed output voltages of 3.3 V, 5.0 V, 12 V, 15 V, and an adjustable
output version. These regulators were designed to minimize the number of external components to
simplify the power supply design. Standard series of inductors optimized for use with the LM2576 are
offered by several different inductor manufacturers.
Since the LM2576 converter is a switch–mode power supply, its efficiency is significantly higher in
comparison with popular three–terminal linear regulators, especially with higher input voltages. In many
28
Page 33
cases, the power dissipated is so low that no heatsink is required or its size could be reduced
dramatically.
A standard series of inductors optimized for use with the LM2576 are available from several different
manufacturers. This feature greatly simplifies the design of switch–mode power supplies.
The LM2576 features include a guaranteed ±4% tolerance on output voltage within specified input
voltages and output load conditions, and ±10% on the oscillator frequency (±2% over 0°C to 125°C).
External shutdown is included, featuring 80 mA (typical) standby current. The output switch includes
cycle–by–cycle current limiting, as well as thermal shutdown for full protection under fault conditions.
• Adjustable Version Output Voltage Range, 1.23 to 37 V ±4% Maximum Over Line and Load
Conditions
• Guaranteed 3.0 A Output Current
• Wide Input Voltage Range
• Requires Only 4 External Components
• 52 kHz Fixed Frequency Internal Oscillator
• TTL Shutdown Capability, Low Power Standby Mode
• High Efficiency
• Uses Readily Available Standard Inductors
• Thermal Shutdown and Current Limit Protection
• Moisture Sensitivity Level (MSL) Equals 1
