7. MULTI STANDARD SOUND PROCESSOR

The MSP34x0G family of single-chip Multistandard Sound Processors covers the sound processing of all analogue TV­Standards 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 BT SC and EIA-J. The
MSP 34x1G has optimum stereo performance without any adjustments.

8. VIDEO SWITCH TEA6415

In case of three or more external sources are used, the video switch IC T EA6415 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 bet ween 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. E ach 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 exter nal resistor. It is possible to have the same input connected to several outputs.

9. 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 7KHKLJKHIILFLHQF\RIWKH73$'HOLPLQDWHVWKHQHHGIRU

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
ofgainfrom–56dBto20dB.

An integrated 5-V regulated supply is provided for powering an external headphone amplifier.

10. 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 d ifferent 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 i n 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.

11. MICROCONTROLLER

The Micronas SDA 55xx TV microcontroller is dedicated to 8 bit applications for TV control and provides dedicated
graphic features designed for modern low class to mid range TV sets. The SDA 55xx provides also an integrated
general purposefully 8051-compatible microcontroller with specific hardware features especially suitable in TV sets.
The microcontroller core has been enhanced to provide powerful features such as memory banking, data pointers and
additional interrupts, etc. The internal XRAM consists of up to 16 kBytes. The microcontroller provides an internal
ROM of up to 128 kBytes. ROMless versions can access up to 1 MByte of external RAM and ROM. The 8-bit
microcontroller runs at 33.33 MHz internal clock. SDA 55xx is realized in 0.25 micron technology with 2.5 V supply
voltage for the core and 3.3 V for the I/O port pins to make them TTL compatible. Based on the SDA 55xx
microcontroller the MINTS software package was developed and provides dedicated device drivers for many Micronas
video & audio products and includes a full blown TV control SW for the PEPER application chassis. The SDA 55xx is
also supported with powerful design tools like emulators from Hitex, Kleinhenz, iSystems, the Keil C51 Compiler and
TEDIpro OSD development SW by Tara Systems.

12. SERIAL ACCESS CMOS 4Kx8(32KBit)EEPROM 24C32A

The Microchip Technology Inc. 24AA32A/24LC32A(24XX32A*) is a 32 Kbit Electrically Erasable PROM. The device is
organized as four blocks of 8K x 8-bitmemory with a 2-wire serial interface. Low-voltage design permits operation
down to 1.8V, with standby and active currents of only 1μA and 1mA, respectively. It has been developed for
advanced, low-power applications such as personal communications or data acquisition. The 24XX32A also has a
page write capability for up to 32 bytes of data. Functional address lines allow up to eight devices on the same bus, for
up to 256Kbits address space.

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ORDGQHHGVDQH[WHUQDOWUDQVLVWRU,WLVSRVVLEOH

PIN DESCRIPTIONS
A0, A1, A2 Chip Address Inputs

The A0...A2 inputs are used by the 24C32 for multiple device operation and conform to the two-wire bus stan­dard. The levels applied to these pins define the address block occupied by the device in the address map. A

particular device is selected by transmitting the corresponding bits (A2, A1, and A0) in the control byte.

SDA Serial Address/Data Input/Outpu

This is a bidirectional pin used to transfer addresses and data into and data out of the device. It is an open drain
terminal; therefore the SDA bus requires a pull-up resistor to VCC (typical 10KQ for 100 kHz, 1KQ for 400 kHz).

For normal data transfer SDA is allowed to change only during SCL low. Changes during SCL high are reserved
for indicating the START and STOP conditions.

SCL Serial Clock

This input is used to synchronize the data transfer from and to the device.

15.13.1.

Introduction

The MSP 34x1G 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 34x1G.
The MSP 34x1G has all functions of the MSP 34x0G with the addition of a virtual surround sound feature.

Surround sound can be reproduced to a certain extent with two loudspeakers. The MSP 34x1G includes the
Micronas virtualizer algorithm “3D-PANORAMA” which has been approved by the Dolby 1) Laboratories for with

the "Virtual Dolby Surround" technology. In addition, the MSP 34x1G includes the “PAN-ORAMA” algorithm.

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.

The MSP 34x1G 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).

15.14. M29W040B

15.14.1. Description

The M29W040B is a 4 Mbit (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 p rocess of programming or erasing the memory by taki ng 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 o f the memory. They allow simple connection to

most microprocessors, often without additional logic.

15.23. LM2576

15.23.1. 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 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.

15.31. MAD4868A

15.31.1. General Description

The Micronas Audio Delay IC MAD 4868A acts as a delay line for TV audio and consumer audio applications.
The IC is designed for synchronizing audio and video signals ensuring "Lip Sync" by delaying the audio signal
with the same amount of time as the video signal is delayed in a TV's video processing.

For TV designs, independent signals for loudspeakers, headphones, and line-out or S/PDIF out must be pro­vided, resulting in the need to delay six independent audio channels.

15.31.2.

Features

x 32 k audio samples RAM:
x Total delay time of 680 ms at 48 kHz or 1020 ms at 32 kHz sampling rate

- 32/18-bit word width:

x 32-bit High-Resolution mode or 18-bit Standard mode
x Sampling rates from 32 kHz to 48 kHz for

serial 8-channel mode are supported

x Sampling rates from 4 kHz to 192 kHz for

parallel 2-channel mode are supported

x Memory allocation:
x MAD 4868A's memory can be allocated for 1... 8 audio channels. Delay time can be programmed for

each channel individually.

15.31.3.

Interfaces

x 8-channel Micronas I2S input and output:
x In combination with Micronas ICs (serial mode) (e.g. MSP 44/46xyK, MAS 35xyH), eight audio channels

can be routed through MAD 4868A by using four lines only.

x 4x2-channel standard I

2

S inputs and outputs (paral

lel mode) allow routing eight audio channels with
sampling rates of 4... 192 kHz through MAD 4868A

2

x I

C control for delay time programming

x Address select to set one out of two available I

2

C addresses.
