MSP 34x1G PRELIMINARY DATA SHEET

Multistandard Sound Processor Family with Virtual Dolby Surround

Release Note: Revision bars indicate significant changes to the previous edition.The hardware and software description in this document is valid for the MSP 34x1G version B8 and following versions.

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 1–1 shows a simplified functional block diagram of the MSP 34x1G.

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

Surround sound can be re produce d to a certain extent with two loudspeakers. The MSP 34x1G includes the Micronas virtualizer alg orithm “3D-PANORAMA” which has been approved by the Dolby

Laboratories for compliance with the " Virtual Do lby 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 Committe e (BTSC) . The DBX noise reduction, or alternatively, Micronas Noise Reduction (MNR) is performed alignment free.

Other processed sta ndards are the Japanese FM-FM multiplex standard (EIA-J) and the FM Stereo Radio standard.

Current ICs have to perform adjustment p rocedures i n order to achieve good stereo separatio n for BTSC a nd EIA-J. The MSP 34x1G has optimum stereo performance with out any adjustments.

All MSP 34xxG versions are pin compatible to the MSP 34xxD. Only minor modifications are necessary to adapt a MSP 34xxD controlling software to the MSP 34xxG. The MSP 34x1G further simplifies controlling software. Standard se lection requires a single

C transmission only.

I The MSP 34x1G has built-in autom atic functions: T he

IC is able to detect the actual sound standard automatically (Automatic Standard Detection). Furthermore, pilot levels and identificatio n signals can be evaluated internally with subsequent switching between mono/ stereo/bilingual; no I

C interaction is neces sary (Auto-

matic Sound Selection). The ICs are produced in submicron CMOS technology.

The MSP 34x1G is available in the following packages: PLCC68 (not intended for new designs), PSDIP64, PSDIP52, PQFP80, and PLQFP64.

MSP 34x1G PRELIMINARY DATA SHEET

2.1. Architecture of the MSP 34x1G Family

Fig. 2–1 on page 9 shows a simplified block diagram of the IC. The block diagram contains all features of the MSP 3451G. Other members of the MSP 34x1G family do not have the complete set of features: The demodulator handles only a subset of the standards presented in the demodulator block; NICAM processing is only possible in the MSP 3411G and MSP 3451G.

2.2. Sound IF Processing

2.2.1. Analog Sound IF Input

The input pins ANA_IN1+, ANA_IN2+, and ANA_IN offer the possibility to connect two different sound IF (SIF) sources to the MSP 34x1G. The analog-to-digital conversion of the preselected sound IF si gnal is done by an A/D-converter. An analog automatic gain circuit (AGC) allows a wide range of input levels. The highpass filters for med by the coupling capaci tors at pins ANA_IN1+ and ANA_IN2+ see Section 8. “Appendix E: Application Circuit” on page 103 are sufficient in most cases to suppress video components. Some combinations of SAW fi lters and sound IF mixer ICs, however, show large pic ture components on their outputs. In this case, further filtering is recommended.

2.2.2. Demodulator: Standards and Features

The MSP 34x1G is able to demodulate all TV-sound standards world wide including the digita l NICAM system. Depending on the MSP 34x1G version, the following demodulation modes can be performed:

A2 Systems: Detection and demo dulation o f two separate FM carriers (FM 1 and FM2), demodulation and evaluation of the identification signal of carrier FM2.

NICAM Systems: Demodulation and decoding of the NICAM carrier, detection and demodulation of the analog (FM or AM) ca r rier. For D/K-NICAM, the F M ca rrier may have a maximum deviation of 384 kHz.

Very high deviation FM-Mono: Detection and robust demodulation of one FM carr ier wit h a maximum deviation of 540 kHz.

BTSC-Stereo: Detection and FM demodulation of the aural carrier resulting in the MTS/MP X signal. Detection and evaluation of the pilot carri er, AM demodulation of the (L carrier. Processing of DBX noise reduction or Micronas Noise Reduction (MNR).

The demodulator blocks of all MSP 34x1G versions have identical user interfaces. Even completely di fferent systems like the BTSC and NICAM systems are controlled the same way. Standards are selected by means of MSP Standard Cod es. Automatic processes handle standard detection and identification without controller interaction. The key features of the MSP 34x1G demodulator blocks are

Standard Selection: The controlling of the demodulator is minimized: All parameters, such as tuning frequencies or filter bandwidth, are adjusted automatically by transmitting one single value to the STANDARD SELECT register. For all standards, specific MSP standard codes are defined.

Automatic Standard Detection: If the TV sound standard is unknown, the MSP 34x1G can automatically detect the actual standard, switch to that standard, and respond the actual MSP standard code.

Automatic Car rier Mute: To prevent no ise effects or FM identification problems in the absence of an FM carrier, the MSP 34x1G offers a configurable carrier mute feature, which is activated automatically if th e T V sound standard is selected by means of the STANDARD SELECT register. If no FM carrier is detected at one of the two MSP demodula tor channels, the corresponding demodulator output is muted. This is indicated in the STATUS register.

−R)-carrier.

PRELIMINARY DATA SHEET MSP 34x1G

2.2.3. Preprocessing of Demodulator Signals

The NICAM signals must be processed by a deemphasis filter and adjusted in level. The analog demodulated signals must be processed by a deemphasis filter, adjusted in level, and dematrixed. The correct deemphasis filters ar e already selected by setting the standard in the STANDARD SELECT register. The level adjustment has to be done by means of the FM/ AM and NICAM prescale registers. The necessary dematrix function depends on the selected sound standard and the actual broad casted sound mode (mono, stereo, or bilingual). It can be manually se t by the FM Matrix Mode register or automatically by the Automatic Sound Selection.

2.2.4. Automatic Sound Select

In the Automatic Sound Select mode, the dematrix function is automatically selected based on the identification information in the STATUS register. No I

interaction is nec essary when t he broadcasted sou nd mode changes (e.g. from mono to stereo).

The demodulator su pports the identifica tion check by switching between mono-compatible standards (standards that have the same FM-Mono car rier) automa tically and non-audible. If B/G-FM or B/G-NICAM is selected, the MSP will switch between these standards. The same action is performed for the standards: D/K1-FM, D/K2-FM , D/K3-FM a nd D/K-NICAM. Switching is onl y done in the a bsenc e of any ste reo or bilingual identification. If identification is found, the MSP keeps the detected standard.

In case of high bit-error rates, the MSP 34x1G automatically falls back from digit al NICAM sound to analog FM or AM mono.

– “Stereo or A” channel: Analog or digital mono

sound, stereo if available. In case of bilingual broadcast, it contains language A (on left and right).

– “Stereo or B” channel: Analog or digital mono

sound, stereo if available. In case of bilingual broadcast, it contains language B (on left and right).

Fig. 2–2 and Table 2–2 show the source channel assignment of the demodulated signals in case of Automatic Sound Select mode for all sound standards.

Note: The analog primary input channel contains the signal of the mono FM/AM carr ier or the L+R s ignal of the MPX carrier. The secondary input channel contains the signal of the 2nd FM carrier, the L-R signal of the MPX carrier, or the SAP signal.

2.4. Source Selection and Output Channel Matrix

The Source Selec tor makes it poss ible to distribute al l source signals ( one of the demodulator source channels, SCART, or I

S input) to the de sired output ch annels (loudspeaker, headphone, etc.). All input a nd output signals can be processed simultaneously. Each source channel is identified by a unique source address.

For each output channel, the s ound mode can be set to sound A, sound B, stereo, or mono by means of the output channel matrix.

If Automatic Sound Select is on, the output channel matrix can stay fixed to stereo (transparent) for demodulated signals.

2.5. Audio Baseband Processing

2.5.1. Automatic Volume Correction (AVC)

Different sound sources (e.g. terrest rial c hannels, SAT channels, or SCART) fairly often do not have the same volume level. Advertisements during movies usually have a higher volume level than the movie itself. This results in annoying volume changes. The AVC solves this problem by equalizing the volume level.

To prevent clipping, the AVC’s gain decreases quickly in dynamic boost conditions. To suppress oscillation effects, the gain increases rather slowly for low level inputs. The decay time is p rogrammable by means of the AVC register (see page 33).

2.5.2. Loudspeaker and Headphone Outputs

The following baseband features are implemented in the loudspeaker and headphone output channels: bass/treble, loudness, balanc e, and volume. A square wave beeper can be added to the loudspeaker and headphone channel. The loudspeaker channel additionally performs: equalizer (not simultaneously with bass/treble), spatial effects, and a subwoofer crossover filter.

2.5.3. Subwoofer Output

The subwoofer signal is created by combin ing the left and right chan nels directly behind the loudness block using the formula (L+R)/2. Due to the division by 2, the D/A converter will not be overloaded, even with full scale input sign als. The subwoofer signal is fil tered by a third-order low-pass wi th programmable corner frequency followed by a level adjustment. At the loudspeaker channels, a complementary high-pass filter can be switched on. Subwoofer and loudspeaker output use the same volume (Louds peaker Volum e Register).

2.5.4. Quasi-Peak Detector

The quasi-peak reado ut register can be used to read out the quasi-pe ak level of any input source. The feature is based on following filter time constants:

attack time: 1.3 ms decay time: 37 ms

For input signals ranging from AVC maintains a fixed output level of

−24 dBr to 0 dBr, the

−18 dBr. Fig. 2–4

shows the AVC output level versus its input level. For prescale and volume registers set to 0 dB, a level of 0 dBr corresponds to full scale input/output. This is

2.5.5. Micronas Dynamic Bass (MDB)

The Micronas Dynamic Bass system (MDB) extends the frequency range of loudspeakers or headphones.

After the adaption of MDB to the loudspeakers and the cabinet, fur ther customizing of MDB allows individual fine tuning of the sound.

Amplitude (db)

The MDB is placed in the su bwoo fer path. For applications without a subwoofer, the enhanced bass signal can be added back onto the Left/Right c hannels (see Fig. 2–1 on page 9). Micronas Dynamic Bass combines two effects: dynamic amplification and adding harmonics.

2.5.5.1. Dynamic Amplification

Low frequency signals can be boosted while the output signal amplitude is mea sured. If the amplitude comes close to a definable limit, the gain is reduced automatically in dynamic Volume mode. Therefore, the system adapts to the signal amplitud e which is really present at the output of th e MSP device. Clipping effects are avoided.

2.5.5.3. MDB Parameters

Several parameters allow tuning the characteristics of MDB according to the TV loudspeaker, the cabinet, and personal preferences (see Table 3–11). For more detailed information on how to set up MDB, please refer to the corresponding application note on the Micronas homepage.

2.6. Virtual Surround System Application Tips

2.6.1. Sweet Spot

Good results are on ly obtained in a rather close area along the middle ax is between the two loudspeakers: the sweet spot. Moving away from this position degrades the effect.

Fig. 2–5: Dynamic amplification

2.5.5.2. Adding Harmonics

MDB exploits the psychoacousti c phenomenon of the ‘missing fundamental’. Adding harmonics of the frequency components be low the cutoff frequency gives the impression of actually hearing the low frequency fundamental. In other words: The listener has the impression that a loudspeaker system seem s to repr oduce frequencies althoug physically not possible.

2.6.2. Clipping

For the test at Dolby Labs, it is very important to have no clipping effects even with worst case signals. That is, 2 Vr ms input sign al may not clip. The SCART Input Prescale register has to be set to values of 19 (25

) or lower (see SCART Input Prescale o n page

PRELIMINARY DATA SHEET MSP 34x1G

2.6.3. Loudspeaker Requirements

The loudspeakers used and their positioning inside the TV set will greatly influence the performance of the virtualizer. The algorithm works with the direct sound path. Reflected sound waves reduce the effect. So it’s most important to have as much direct sound as possible, compared to indirect sound.

To obtain the approval for a TV set, Dolby Laboratories require mounting the lo udspeakers in front of the set. Loudspeakers radiating to the side of the TV set will not produce convincing effects. Good di rectionality of the loudspeakers towards the listener is optimal.

The virt ualizer was specially developed for implementation in TV sets. Even for rather small stereo TV's, sufficient sound effects can be obtained. For small sets, the loudspeaker placement sho uld be to the si de of the CR T; for large screen se t s (or 16:9 sets), m ou nt ing the loudspeakers below the CRT is acceptable (large separation is preferred, low freq uency speakers should be outmost to avoid cancellation effects). Using external loudspeakers with a la rg e s te re o b as e wi ll n ot create optimal effects.

The loudspeakers should be able to reproduce a wi de frequency range. The most impor tant fr equency range starts from 160 Hz and ranges up to 5 kHz.

Great care has to be taken with syst ems that us e one common subwoofer: A single loudspeaker cannot reproduce vir tual sound locations. The crossover frequency must be lower than 120 Hz.

2.7. SCART Signal Routing

2.7.1. SCART DSP In and SCART Out Select

The SCART DSP Input Select and SCART Output Select blocks include full matrix switching facilities. To design a TV set with four pairs of SCART-inputs and two pairs of SCART-outputs, no external switching hardware is required. The switches are controlled by the ACB user register (see page 41).

2.7.2. Stand-by Mode

If the MSP 34x1G is switched off by first pulling STANDBYQ low and t hen (a fter >1

µs delay) switching

off DVSUP and AVSUP, but keeping AHVSUP (‘Stand-by’-mode), the SCART switches maintain their position and function. This allows the copying from SCART-input to SCART-output in the TV set’s stand-by mode.

In case of power on or starti ng from stand-by (switching on the DVSUP and AVSUP, RESETQ going high 2 ms later) , all inte r nal registe rs except th e ACB register (page 41) are reset to the default configuration (see Table 3–5 on page 20). The reset positi on of the ACB register becomes act ive after the first I

C transmission into the Baseband Processing part. By transmitting the ACB register first, the reset state can be redefined.

2.6.4. Cabinet Requirements During listenin g tests at Dolby Laboratories, no reso-

nances in the cabinet should occur.

Good material to check for resonances are the Dolby Trailers or other dynamic sound tracks.

MSP 34x1G PRELIMINARY DATA SHEET

2.8. I2S Bus Interface

The MSP 34x1G has a synchronous master/slave input/output interface running on 32 kHz.

The interface accepts two formats:

S_WS changes at the word boundary

1. I

2. I

S_WS changes one I2S-clock period before the

word boundaries.

S options are set by means of the MO DUS and

All I the I2S_CONFIGURATION registers.

S bus interface consists of five pins:

The I – I 2S _ DA _ I N 1 , I 2 S _ DA _ I N 2 :

S serial data input: 16, 18....32 bits per sample

– I2S_DA_OUT:

S serial data output: 16, 18...32 bits per sample

– I2S_CL:

S serial clock

– I2S_WS:

S word strobe signal defines the left and right

sample

If the MSP 34x1G serves as the master on the I

interface, the clock and word strobe lines are driven by the IC. In this mode, only 16 or 32 bits per sample can be selected. In slave mode, these lines are input to the IC and the MSP clock is synchronized to 576 times the I2S_WS rate (32 kHz). NICAM o peration is not possible in slave mode.

S timing diagram is shown in Fig. 4–28 on

An I page 71.

2.9. ADR Bus Interface

For the ASTRA Digital Radio System (ADR), the MSP 340 1G, MSP 3411G, and MSP 3451G performs preprocessing such as carrier selection and filtering. Via the 3-line ADR-bus, the resulting signals are transferred to the DRP 3510A coprocessor, where the source decoding is per formed. To be prepared for an upgrade to ADR with an additional DRP board, the following lines of MSP 34x1G should be provided on a feature connector:

– AUD_CL_OUT – I2S_DA_IN1 or I2S_DA_IN2 – I2S_DA_OUT – I2S_WS – I2S_CL – ADR_CL, ADR_WS, ADR_DA

For more details, please refer to the DRP 35 10A data sheet.

2.10. Digital Control I/O Pins and Status Change Indication

The static level of the digital input/output pins D_CTR_I/O_0/1 is switchable between HIGH and LOW via the I (see page 41). This enables the control ling of exter nal hardware switches or other devices via I

C-bus by means of the ACB register

C-bus.

The digital input/outpu t pins can be set to hig h impedance by means of the MODUS register (see page 26). In this mode, the pi ns can be used as input. The current state can be read o ut of the STATUS register (see page 28).

Optionally, the pin D_CTR_I/O_1 can be used as an interrupt request signa l to the c ontrol ler, indicating any changes in the read register STATUS. This makes polling unnecessary, I

C bus interactions are reduced to a minimum (see STATUS register on page 28 and MODUS register on page 26).

2.11. Clock PLL Oscillator and Crystal Specifications

The MSP 34x1G derives all internal system clocks from the 18.432-MHz oscillator. In NICAM or in I

SSlave mode, the clock is phase-locked to the corresponding source. Therefore, it is not possible to use NICAM and I

S-Slave mode at the same time.

For proper performance, the MSP clock oscillator requires a 18.432-MHz crystal. Note that for the phase-locked modes (NICAM, I

S-Slave), crystals with

tighter tolerance are required.

3. Control Interface

C Bus Interface

3.1. I

The MSP 34x1G is controlled via the I

C bus slave

interface. The IC is selected by transmitting one of the

MSP 34x 1G device addresses. In order to allow up to three MSP ICs to be connected to a single bus, an address select pin (ADR_SEL) has been implemented. With ADR_SEL pulled to high, low, or left open, the MSP 34x 1G res ponds to different device addresses. A device address pair is defined as a write address and a read address (see Table 3–1).

Writing is done by sending the write device address, followed by the subaddress byte, two address bytes, and two data bytes.

Reading is done by sending the wr ite device address, followed by the subaddress byte and two address bytes. Without sending a stop c ondi tion, r ea din g of t he addressed data is completed by sending the device read address and reading two bytes of data.

response time is about 0.3 ms. If the MSP cannot accept another byte of data (e.g. while servicing an internal int err upt), it ho lds th e clock line I2C_CL l ow to force the transmitter into a wait state. The I Master must read back the clock line to detect when the MSP is ready to r ecei ve the next I

C transmission.

C Bus

The positions within a transmission where this may happen are indicated by ’Wait’ in Section 3.1.3. The maximum wait period of the MSP during normal operation mode is less than 1 ms.

3.1.1. Inte rnal Hardware Error Handling

In case of any hardware problems (e.g. interruption of the power supply of the MSP), the MSP’s wait period is extended to 1.8 ms. After thi s time perio d elapses, the MSP releases data and clock lines.

3.3.1. User Registers Overview

The MSP 34x1G is co ntrolled by mean s of use r registers. The complete lis t of all user registers is given in Table 3–5 and Table 3–6. The registers are partitioned into the Demodulator section (subaddress 10 writing, 11 ing sections (subaddress 12

for reading) and the Baseband Process -

hex

for writing, 13

hex

for for

reading). Write and rea d registers are 16 bit wide, whereby the

MSB is denoted bit[15]. Transmissions via I

C bus have to take place in 16-bit words (two byte transfers, with the most significant byte transferred first). All write register s, except the demodulator write registers are readable.

Unused parts of the 16-bit write registers must be zero.

Addresses not given in this table must not be accessed.

For reasons of software compatibility to the MSP 34 xx D, a Manual/Compatibility Mode i s available. More read and wri te registers toge ther with a detailed description can be found in “Appendix B: Manual/Compatibility Mode” on page 85.

MSP 34x1G PRELIMINARY DATA SHEET

3.3.2.1. STANDARD SELECT Register

The TV sound standar d of the MSP 34x1G demodulator is determined by the STANDARD SELECT register. There are two ways to use the STANDARD SELECT register:

– Setting up the demodulator for a TV sound standard

by sending the corresponding standard code with a single I

– Starting the Automatic Standard Detection for ter-

restrial TV standards. This is the most comfortable way to set up the demodulator. Within 0.5 s, the detection and setup of the actual TV sound standard is performed. The detected standard can be read out of the STANDARD RESULT register by the control processor. This feature is recommended for the primary setup of a TV set. Outputs should be muted

during Automatic Standard Detection. The Standard Codes are listed in Table 3–7. Selecting a TV sound standard via the STANDARD

SELECT register initializes the demodulator. This includes: AGC-settings and carrier mute, tuning frequencies, FIR-filter set tings, demodulation mode ( FM, AM, NICAM), deemphasis and identification mode.

TV stereo sound standa rds that are unavailable for a specific MSP version are processed in analog mono sound of the standard. In that cas e, stereo or bilingual processing will not be possible.

For a complete setup of the TV sound processing from analog IF input to the source selection, the transmissions as shown in Section 3.5. are necessary.

C bus transmission.

3.3.2.2. Refresh of STANDARD SELECT Register

A general refresh o f th e S TANDARD SELECT register is not allowed. However, the following method enables watching the MSP 34x1G “alive” status and detection of accidental resets (only versions B6 and later):

– After Power-on, bit[15] of CONTROL will be set; it

must be read once to enable the reset-detection feature.

– Reading of the CONTROL register and checking

the reset indicator bit[15] .

– If bit[15] is “0”, any refresh of the STANDARD

SELECT register is not allowed.

– If bit[15] is “1”, indicating a reset, a refresh of the

STANDARD SELECT register and all other MSPG registers is required.

3.3.2.3. STANDARD RESULT Register

If Automatic Standard Detection is selected in the STANDARD SELECT regi ster, status and result o f the Automatic Standard Detection process can be read out of the STANDARD RESULT register. The possible results are based on the mentioned Standard Code and are listed in Table 3–8.

In cases where n o sound st andard h as been detected (no standard present, too mu ch noise, strong interferers, etc.) the STANDARD RESULT register contains 00 00 actions (for example set the standard according to a preference list or by manual input).

. In that case, the controller has to start further

hex

For reasons of software compatibility to the MSP 34x x D, a Manual/Compatibility mode is available. A detailed description of this mode can be found on page 85.

As long as the STANDA RD RESULT register contains a value greater than 07 FF Detection is still active. During this period, the MODUS and STANDARD SELECT register must no t be written. The STATUS register will be updated when the Automatic Standard Detection has finished.

If a present sound s tandard is unavailable fo r a specific MSP-version, it detects and switches to the analog mono sound of this standard.

Example: The MSPs 3421G and 3441G will detect a B/G-NICAM signal as standa rd 3 a nd will switch to the analog FMMono sound.

3dynamic With large scale input signals, positiv e v ol ume sett ings ma y lead to sign al clipping . The MSP 34x1G loudspea ker and headphon e volume func tion is div ided in to a

digital and an analog sectio n. With Fast Mute, volume is reduced to mute position by digital volume only. Analog volume is not changed. This reduces any audible DC plops. To turn volume on again, the volume step that has been used before Fast Mute was activated must be transmitted.

If the clipping mode is set to “reduce volume”, the following rule is used: T o prevent severe clipping effects with bass, treble, or equalizer boosts, the internal volume is automatically limited to a level where, in combination with either bass, treble, or equalizer setting, the amplification does not exceed 12 dB.

If the clipping mode is “reduce tone control”, the bass or treble value is reduced if ampli fication exceeds 12 dB. If the e qualizer is switched on , the g ain of those bands is reduced, where amplific ation together with volume exceeds 12 dB.

If the clipping mode is “compromise”, the bass or treble value and volume are reduced half and half if amplification exceeds 12 dB. If the equalizer is switched on, the gain of those bands is reduced half and half, where amplification together with volume exceeds 12 dB.

If the clipping mode is “dynamic”, volume is reduced automatically if the signal amplitudes would exceed

−2 dBFS within the IC. For operation of MDB, dyna-

mic mode must be switched on.

Higher resolution is pos sible: an LSB step in the nor mal range r esults in a g ain step of about 1/8 dB, in the extended range about 1/4 dB.

With positive bass settings, internal clipping may occur even with overall volume less than 0 dB. This will lead to a clipped outpu t signal. Therefore, it is not recommended to set bass to a value tha t, in conjunct ion with volume, would result in an overall positive gain.

Spatial effects should not be used together with 3D-PANORAMA or PANORAMA.

There are several spatial effect modes available: In mode A (low byte = 00

), the spatial effect depends on the sou rce mode. If

hex

the incoming signal is mono, Pseudo Stere o Effect is active; for stereo s ignals, Pseudo Stereo Effect and Stereo Basewidth Enlargement is effective. The strength of the effect is controllable by the upper byte. A negative value reduces the stereo image. A strong spatial effect is recommended for small TV sets where loudspeaker spacing is rather close. For large screen TV se ts, a more moderate spatial effect is recommended.

In mode B, only Stereo Basewidth Enla rg eme nt is effective. For mono input signals, the Pseudo Stereo Effect has to be switched on.

It is worth mentioning, that all spatial effects affect amplitude and phase response. With the lower 4 bits, the fre quency respon se can be custom ized. A value of 0 function for L or R only signals. A value of 6 only signals, but a low-pass function for center signals. By u sing 8

yields a flat r esponse for center signals (L = R), but a high-pass

, the fre-

quency response is automatically adapted to the sound material by choosing an optimal high-pass gain.

3.4. Programming Tips

This section descr ibes the pre ferred method for initializing the MSP 34x1G. Th e initializ ation is grouped in to four sections:

– SCART Signal Path (analog signal path) – Demodulator – SCART and I

S Inputs

– Output Channels See Fig. 2–1 on page 9 for a complete signal flow.

SCART Signal Path

1. Select analog input for the SCART baseband processing (SCART DSP Input Select) by means of the ACB r egist er.

2. Select the source for each analog SCART output (SCART Output Select) by means of the ACB register.

Demodulator

For a complete setup of the TV sound processing from analog IF input to the source selection, the following steps must be performed:

1. Set MODUS register to the preferred mode and Sound IF input.

2. Choose pref er r ed p r e sca le (F M an d N I CA M ) values.

3. Write STANDARD SELECT register.

4. If Automatic Sound Select is not active: Choose FM matrix repeatedly according to the sound mode indicated in the STATUS register.

SCART and I

S Inputs

1. Select preferred prescale for SCART.

2. Select preferred prescale for I

S inputs

(set to 0 dB after RESET).

Output Channels

1. Select the source channel and matrix for each output channel.

2. Set audio baseband processing.

3. Select volume for each output channel.

3.5. Examples of Minimum Initialization Codes

Initialization of the MS P 34x1G acco rding to thes e list ings reproduces sound of the selected standard on the loudspeaker output. All numbers are hexadecimal. The examples have the following structure:

1. Perform an I

C controlled reset of the IC.

2. Write MODUS register (with Automatic Sound Select).

3. Set Source Selection for loudspeaker channel (with matrix set to STEREO).

4. Set Prescale (FM and/or NICAM and dummy FM matrix).

5. Write STANDARD SELECT regist er.

6. Set Volume loudspeaker channel to 0 dB.

Pins 71, 72 XTAL_IN, XTAL_OUT – Cryst al Input and Output Pins (Fig. 4–20) These pins are connected to an 18.432 MHz crystal oscillator which is digitally tuned by integrated shunt capacitances. An external clock can be fed into XTAL_IN. The audio clock output signal AUD_CL_OUT is derived from the oscillator. External capacitors at each crystal pin to ground (AVSS) are required. It should be verifie d by layout, that no sup ply curr ent for the digital circuitr y is flowing through the ground c onnection p oint.

Pin 73, TP – This pin enables factor y test modes. For normal operation, it must be left vacant.

Pin 80, STANDBYQ – Stand-by In normal operation, this pin must be high. If the MSP 34x 1G is switche d off by first p ullin g STANDBYQ low and then (after >1

µs delay) switching off DVSUP

and AVSUP, but keeping AHVSUP (‘Standby’-mode), the SCART switches maintain their position and function.

* Application Note:

All ground pins shoul d be connecte d to one low-re sistive ground plane. All supply pins should be connected separately with short and low-resistive lines to the power supply. Decoupling capacitors from DVSUP to DVSS, AVSUP to AVSS, and AHVSUP to AHVS S are recommended as closely as possible to these pins. Decoupling of DVSUP and DVSS is most important. We recommend using more than one capacitor. By choosing different values, the frequency range of active decoupling can be extended. In our application boards we use: 220 pF, 470 pF, 1.5 nF, and 10

µF. The

capacitor with the lowest value should be place d nea rest to the DVSUP and DVSS pins.

The ASG pins should be conn ected as cl osely as possible to the MSP ground. If they are lead with the SCART-inputs as shielding lines, they should not be connected to ground at the SCART connector.

quency of the internal PLL and to stabilize the frequency in closed-loop operation. Due to different layouts, the accurate capacitor value should be determined with the customer PCB. The suggested values (1.5...3.3 pF) are figures based on experience and should serve as “start value”.

To adjust the capacitor value, reset the MSP. After the reset, no I

C telegrams should be transmitted. Measure

the frequency at AUD_CL_OUT-pin. Change the capacitor value until the free running frequency matches

18.432 MHz as closely as possible. The higher the capacity, the lower the resulting clock frequency.

Note: To minimize adjustment tolerances for all MSP-generations, it is strongly recommended to use the so-called

MSP-XTAL-REF ICs (available in all packages) for the capacitor adjustment.

6. Appendix B: Manual/Compatibility Mode

To adapt the modes of the STANDARD SELECT register to individual re quirements and for reasons o f com- patibility to the MSP 34x0D, the MSP 34x1G offers an Manual/Compatibility Mode, which pr ovides so phi sticated programming of the MSP 34x1G.

Using the STANDARD SELECT regi ster gene rally provides a more economic way to program the MSP 34x 1G a nd wil l resul t in op timal behavior. There-

fore, it is not recommend to use the Manual/Compatibility mode. In those cases, where the

MSP 34xxD is to be substituted by the MSP 34x1G, the tips given in Section 6.10. on page 101 have to be obeyed by the controller software.

6.3. Manual/Compatibility Mode: Description of Demodulator Write Registers

6.3.1. Automatic Switching between NICAM and

Analog Sound

In case of bad NICAM reception or loss of the NICAM-carrier, the MSP 34x1G offers an Automatic Switching (fall back) to the analog sound (FM/AMmono), without the necessity for the controller of reading and evaluating any parameters. If a proper NICAM signal retur ns, switching back to th is source is performed automatically as well. The feature evaluates the NICAM ERROR_RATE and switches, if necessary, all output channels which are assigned to the NICAM-source, to the analog source, and vice versa.

An appropriate hysteresis algorithm avoids oscillating effects (see Fig. 6–1). STAT US[9] and C_AD_BITS[11] (Addr: 0023 hex) provide information about the actual NICAM-FM/AM-status.

6.3.1.1. Function in Automatic Sound Select Mode

The Automatic Sound Select feature (MODUS[0]=1) includes the procedure mentioned above. By default, the internal ERROR_RATE threshold is set to 700

– NICAM – analog Sound

The ERROR_RATE value of 700 corresponds to a BER of approximately 5.46*10

. i.e.:

Individual configuration of the threshold can be done using Table 6–5. However, the inter nal s etting used by the standard selection is recommended.

The optimum NICAM sound can be assigned to the MSP output chan nels by selecting one of the “Stereo or A/B”, “Stereo or A”, or “Stereo or B” source channels

6.3.1.2. Function in Manual Mode

If the manual mode (MODUS[0]=0) is required, the activation and configuration of the Automatic Switching feature has to be done as described in Table 6–6. Note, that the channel matrix of the corresponding output-channels must be set according to the NICAM-mode and need no t to be changed in the FM/ AM-fallback case.

Note: The use of these register is no longer recom-

mended. It should be used on ly in cases where software compatibility to the MSP 34x0D is required. Using the STANDARD SELECTION register together with the STATUS register provides a more economic way to program the MSP 3 4x1G and to retrieve information from the IC.

All registers except C_AD_ BITs are 8 bits wide. They can be read out of the RAM of the MSP 34x1G if the MSP 34x0D Compatibility Mode is required.

All transmissions take place in 16-bit words. The valid 8-bit data are the 8 LSBs of the received data word.

If the Automatic Sound Selec t feature is not used, the NICAM or FM-identi fication parameters must be re ad and evaluated by the controller in order to enable appropriate switching of the channel select matrix of the baseband processing part. The FM-identification registers are desc ribed in s ection 6.6.1 . To handle the NICAM-sound and to observe the NICAM-quality, at least the registers C_AD_BITS and ERROR_RATE must be read and evaluated by the controller. Additional data bits and CIB bits, if supplie d by the NICAM transmitter, can be obtained by reading the registers ADD_BITS and CIB_BITS.

Average error rate of the NICAM reception in a time interval of 182 ms, which should be cl os e to 0. The in itial and maximum value of ERROR_RATE is 2047. This value is also active if the NICAM bit of MODE_REG is not set . Since th e value is ac hieved by filtering, a certain transition time (approx. 0.5 sec) is unavoidable. Acceptable audio may have error rates up to a value of 700 int. Individual evaluation of this value by the controller and an appropriate threshold may define the fallback mode from NICAM to FM/ AM-Mono in case of poor NICAM reception.

The bit error rate per second (BE R) can be calcul ated by means of the following formula:

6.4.7. Automatic Search Function for FM-Carrier Detection in Satellite Mode

The AM demodulatio n ability of the MSP 34x1G o ffers the possibility to calculate the “field strength” of the momentarily selected FM carrier, which can be read out by the controller. In SAT receivers, this feature can be used to make automati c FM carrier search possible.

For this, the MSP has to be switched to AM-mode (MODE_REG[8]), FM-Prescale must be set to 7F

hex

= +127

, and the FM DC notch (see section

dec

6.5.7.) must be switched off. The sound-IF frequency

range must now be “scanned” in the MSP-channel 2 by means of the programmable quadrature mixer with an appropriate in cremental frequency (i.e. 10 kHz). After each incrementation, a fie ld strength value is available at the quasi-peak de tec tor output (quasi-peak de tec tor source must be set to F M), which must be examined for relative maxima by the controller. This results in either continuing sea rch or switching the MSP back to FM demodulation mode.

During the search p rocess, the FIR2 must be loaded with the coefficient set “AUTOSEARCH”, which enables small bandwidth, resulting in appr opriate field strength characteristics. The absolute field strength value (can be read out of “quasi-peak de tector output FM1”) also gives information on whether a main FM carrier or a subcarrier was detected; and as a practical consequence, the FM bandwidth (FIR1/2) and the deemphasis (50

µs or adaptive) can be switched

accordingly.

Due to the fact that a constant demodulation frequency offset of a few kHz leads to a DC level in the demodulated signal, further fine tun in g o f the found car r ie r ca n be achieved by evaluating the “DC Level Readout FM1”. Therefore, the FM DC Notch must be switched on, and the demodulator part must be switched back to FM-demodulation mode.

The DC level register measures the DC compon ent of the incoming FM sign als (FM1 and FM2). This can be used for seek functions in satel lite recei vers and for IF FM frequencies fine tuning. A too low demodulation frequency (DCO) results in a positive DC-level and vice versa. For further proc essing, the DC content of the demodulated FM signals is suppressed. Th e time constant
