Eco CTV Design with DSP Technology

1. Introduction to VCTI – DSP IC from Micronas

In the television industry, Micronas is well known assupplier of DSP ICS for high-end television and multi-media products for the last few decades. The maindevelopment labs are in Germany at Freiburg andMunich. Micronas is well-known for the digital signalprocessing capabilities for audio and video relatedapplications and they are the market leaders for PIP,double scan, text and NICAM decoders, and digitaltelevision.

Expanding its comprehensive TV system solutionsoffering, Micronas has launched the new VCT 49xyIfamily platform, a complex, yet flexible single-chip TVsolution integrating all IF, audio, video, and control pro-cessing functions into one package. Uniquely sup-porting every TV standard worldwide, the software-and pin-compatible chips can be used in both low-cost mono and high-end TV sets featuring large screenreal flat 16:9 and surround sound.

With one board layout and software design, systemmanufacturers are able to target a range of differentmarkets, reducing development time and cost, as wellas the number of components. Especially for theseproducts, Micronas developed a new package for cus-tomers to lower production costs. Almost all non stan-dard field conditions can be managed with the rich setof VCTI registers. This means, for the TV manufactur-ers, more time is available for quality improvementsand improved market share.

The VCT 49xyI covers all TV Audio standards world-wide, from mono, BTSC-SAP,A2 system, and up toNICAM. It contains the complete audio base-band pro-cessing for up to three loudspeaker applications. Apartfrom basic audio features, the VCT 49xyI includesadvanced sound processing algorithms like: MicronasBASS, Micronas VOICE, Micronas AROUND, SRS,SRS WOW, BBE digital and Virtual Dolby Surround(VDS).

In addition to TV audio, the VCT 49xyI chips can alsoprocess FM radio programs including the radio dataservices RDS and RBDS (USA) without the need forany additional components. The CRT is a perfectmedium to display the information transmitted viathese data services.

The VCT 49xyI family covers all video standardsworldwide - automatic multistandard color demodula-tor. Due to the integrated rich set of video features, e.g.comb filter, horizontal scalar, picture improvementsand the advanced deflection unit, the chip can be usedfrom low-end up to high-end (large screen real flat16:9) TV sets.

The embedded TV controller supports all kinds of TVdata services, including WST, VPS, PDC, CC, V-chipand WSS. The advanced OSD (on-screen display)engine is used to generate sophisticated user menus.It is even possible to compress moving images andtext in order to display images and teletext or userinformation side by side - an impressive feature for16:9 screens. For the cost-sensitive single-scan TV market, Micro-nas offers another special advantage. The VCT 49xyIchips are available in a brand new, cost-effective 88 pinPSSDIP package. The PSSDIP has been specificallydeveloped following customer requests. It is similar toa DIP, but the pins are arranged to increase pin count,keeping package dimensions small. In addition toPSSDIP, the VCT 49xyI is available in standard 144-pin Quat Flat Package (QFP). With this package, anexternal SRAM can be connected to store up to 1,000teletext pages and to support EPG services.

1.1. Introduction to Priyanka 2 Chassis

The Priyanka chassis meets the needs of the vastmarket segment of low cost but good performance TVreceivers with standard features. Three aspectsachieve the low cost target. The cost optimized scal-able architecture of VCTI, low cost–low componentcount peripherals around VCTI and careful selection oflow cost power supply, deflection, audio and videooutput stages. The chassis is designed in a standardPCB size that is very small and yet can be mounted inmost of the TV cabinets. In production, twin PCBs canbe stuffed together and wave soldered thus improvingproductivity.

A detachable power supply (based on Sanken supplycontroller) module and keyboard is introduced in thesame small dimension of the chassis to meet applica-tions where cabinets are to be reduced and yet thecost has to be kept low. This also helps to improve ser-viceability needs of the developing nations with mini-mum tools.

Connectors are reduced to minimum without scarifyingflexibility. For example, since the video amplifier,power supply, and keyboard are breakaway part of themotherboard, direct wiring is possible without need oftwo connectors. Unlike other brands of single chip TVICs that have no audio processing, comb filter, or ste-reo source selection and hence external ICs areneeded for such functions, no additional ICs or mod-ules are needed with VCTI present.

5. Function Block Description

A short summary of different blocks relevant to thePriyanka chassis is presented here. For completedetails refer to VCTI data sheets. The chassis sup-ports the scalability of the VCTI family to some extent.However, due to limited scope of the chassis coveringthe Eco section of TV market, all versions of VCTI arenot usable. The following short descriptions are relatedto scope of Priyanka chassis alone. The capabilities ofVCTI far exceed the scope of the Priyanka chassis andkindly refer to detailed data sheets of VCTI and itsdiversity.

5.1. Tuner

The tuner used is the PLL tuner type Temic 6002PH5or Philips UV 1316. Although the I2C tuner address isthe same, there could be difference in the register datafor different tuners. The tuner supply voltage (5 V)comes from the main power supply unit (discreteSMPS) after the regulator LM317. The 33 V tuningsupply is derived from main supply 110 V from theSMPS (see PSU).

FM radio reception is possible, with reasonable perfor-mance and with appropriate VCTI. However, no spe-cial FM tuner is needed. A normal TV tuner that cantune the FM band (88 to 108 MHz) will do. The AGCfunction (pin 1 of the tuner) is controlled by VCTI(pin14). The tuner IF output is connected to universalSAW filter (8 MHz flat response) and the output of theSAW filter is connected to VCTI (pins16, 17) by shorttracks. After this, the signal processing is in digitaldomain. The tuner body ground is returned to supplyground by thick track for lightning protection.

Note: The AGC capacitor is only 10 nF.

5.2. VIF

This stage is different to conventional VIF stages. TheIF signals coming from the global SAW filter goesthrough an AGC stage before AD-conversion for digitalsignal processing. Complete QSS IF processing withan external single SAW filter (X6966M) is done by theVCTI for all global standards without need for switchingthe SAW filter, even in the case of multistandard TVapplications. (See details VCTI data sheets). Specificstandard dependant response and adaptation to trans-mitter or cable signal is possible in this section. TunerAGC take over point (TOP) adjustment and AFC func-tion are inside this section of IC. The output (CVBSand QSS SIF) is passed to further processing.

5.3. Source Selection

The chassis incorporates audio (2 channel stereo sig-nal) and video signal (CVBS) sockets on the mainboard. The source selection function is inside theVCTI. Recording output (monitor output) is availablefrom the rear of the main board from the Cinch con-nectors. ESD protection is achieved for the externalconnection by simple RC filters and spark gaps on thePCB tracks.

Crosstalk between sources is avoided by keeping trackisolation and short track lengths.

The selected signal source is internally processed andthe features of the audio and video processing arescalable according to the choice of VCTI. Sourceselection is done through I2C and so, no controllerports are needed for the source selection. The rear AVsource signals are fed to pins 12, 13 (audio L,R) and3§ (video). The front AV signals are fed to pins 10, 11(audio L, R) and 35 (video).

5.4. Multistandard Sound Processing

Different versions of VCTI (Eco and basic) can be usedon the chassis. In all versions, multistandard monodecoding is possible in automatic standard selectionmode or forced standard selection mode. See attachedtable for A2 system. For NICAM and BTSC standardsplease refer to VCTI, DSP data sheets.

The chassis can handle all known analog and NICAMTV sound transmission standards.

Thus, adaptations to different country standards arepossible. Either forced single standard (e.g. BG) orautomatic multistandard detection and processing ispossible with very little software overhead. The pro-cessed audio output is available for audio power ampli-fier (pins 4, 5). Audio output is also available at themonitor output (pins 6, 7).

For complete details of all audio features and descrip-tion, please refer to the software hardware matchingdocuments (SHM).

5.5. Video and Multistandard Chroma Processing

External video CVBS (pins 33, 37) or internal videoCVBS from the tuner, after source selection, is passedto the multistandard chroma decoder. The color stan-dard can be identified and decoded automatically inauto mode or can be forced to a single standard.External (not on main PCB) YC or Y, Pb, Pr, or RGBcan also be processed. CVBS monitor output is avail-able on pin 40 through a buffer. A RGB output to CPTis available at the collector of the buffers (Q5, Q6, Q7).The details of the control functions of the color decoderis available in the SHM documents.

5.6. Video Output

A discrete video amplifier can be used due to the pos-sibility to independently adjust the cutoff and gainadjustments from the VCTI. This also helps to reducecost for Eco models.

However, if a reduction of RGB alignment in productionis needed, an auto cutoff feature can be enabled withappropriate video amplifier ICs like the TDA 6107.

5.7. Horizontal Output

The H-output from VCTI is accoupled to the bipolar H-driver BC337. Horizontal driver operates on a low volt-age (12 V) supply to reduce the cost of high voltagetransistor and elcos. The H-output is conventionalBU506D. The flyback capacitor is to be adjusted for dif-ferent H-yoke impedance. The H-output stage sup-ports only 90 deflections that needs no external geom-etry adjustments. The video amplifier supply (180 V)and vertical stage supplies (±13 V) is derived from theline deflection.

5.8. Vertical Output

The vertical output uses TDA 8172 of ST with dualsupply DC coupled yoke. This helps to implementblack switch off. Also the dual supply output stage pro-duces less vertical rattle.

All vertical parameters are adjustable from the DSP.Detection of vertical deflection failure is possible due toclamped vertical pulses applied to DSP (pin 59)V_protect. The set can be switched off automatically toavoid phosphor burnout mark. Vertical sync function isinside DSP with automatic sync to 50 Hz and 60 Hz.Note that the IC’s mounting tab is at –12 V and so, iso-lation is needed for mounting on the common heatsinkwith audio.

5.9. Audio Output

To meet different audio power requirement for differentmarket segments, a family of pin compatible audio out-put ICs from Matsushita is used.

– AN7523 up to 3 W (mono) at 11 V supply (16 Ohms)

– AN7522 up to 5 W + 5 W (stereo) at 11 V supply (8 Ohms)

– AN17820 up to 10 W+10 W (stereo) at 15 V audio supply (8 Ohms)

The first 9 pins of mono and stereo versions are ofcommon functions.

The audio amplifier can be put to stand-by mode bythe absence of DC voltage from aux supply from LOTat the stand-by pin of audio IC (pin5). Pin 9 is the mutepin and also the PWM volume control pin. If pin 9 isused as volume control the DSP audio output (pins 4,5) should be about 200 mV for nominal modulation of54%. If DSP volume is used, then the pin 9 of theaudio output should be held at 1.5 V to allow audiooutput to speakers. During switch on and switch offmute should be enabled to reduce PLOP sound at thespeakers.

5.10. Power Supply

The power supply is designed with the industry stan-dard Sanken controller that covers universal powersupply range (90 V to 270 V) operating in flybackmains isolated mode. The power supply can deliver upto 70 W RMS power to TV chassis.

The H-deflection supply is 112 V and audio supply is11 V or 15 V depending upon the power output. TheDC supply for the small signal is derived from anotheraux supply 8 V.

During stand-by the 5 V and some 3.3 V are switchedoff. LM317 regulators maintain part of 3.3 V and 1.8 V,which needs to be retained during stand-by. The inputfilters help to reduce line interference.

The mains elco is of higher voltage to take care of sup-ply voltage fluctuations on the higher side.

All the aux supplies are fitted with fuseable resistors toimprove short circuit and over current protection. Themains input is also fitted with a slow blow fuse a safetymeasure.

The on-off switch is mounted separately to improvecabinet flexibility.

Micronas Dec. 20, 2004; 6251-573-4-1AK 7


5.11. Local Key Pads, IR and Control

Usual 4-key local keypad is used for the channel andvolume changes. A fifth key can be used as stand-byswitch, where mains on-off switch is not mandatory.The IR receiver is supplied with 3.3 V and the receivedcode is input to pin 50. The LED is operated from theLED port (pin 53), which is on during stand-by and dimduring receiver on mode. The NVM stores standardsettings that are changed during operation of thereceiver by either user or by service personal tochange some service parameters. Few ports are avail-able for future expansion. The NVM is always writeprotected and anly write protected for writing into it,

controlled by the processor. This means that for even-tually CRT flashes, as well as pulses during switch offfrom mains, the NVM content is protected (pin 47 ofDSP).

5.12. VCTI DSP

The pinning details are given in the table below. To gethigh quality picture and sound with acceptable S/N theIC has dedicated supply and ground pins. The decou-pling ceramic capacitors are very close to IC pins. Thedecoupling chokes should have low self resistance(< 0.5 Ohms). The crystal frequency is 20.25 MHz.

A short summary of few critical measurements andtypical performance are given in Fig. 6–1

7. Field Report

Although most of the manufacturers have a lot of expe-rience to solve the field complaints, there is alwayssomething typical to key components in a new designand a summary of some problems and solutions aregiven. However, please contact our tech staff in caseyou need more latest updates.

7.1. Sound Crackling in some Channels

Picture is normal but sound is crackling. Most oftendue to the following reasons:

– Sound carrier level lower than normal.

– SIF centre frequency far from normal (say 150 kHz)

– Above + over modulation

Cause of crackling is when carrier level is too low forautomatic detection or off set and deviation is largeand so the sound demodulation fails on peaks ofsound. It is possible to switch on the over modulationbit to solve most of over modulation problems. Severecentre freq shift (>200 kHz) needs an algorithm todetect and correct the centre freq shift. It is better tomanually change the freq of DCO and store in NVM.

– Sound crackling due to week wanted channel (N) and strong adjacent channel (N+1) in VHF bands

The adjacent channel video gets passed along withthe wanted SIF to the audio detector. In case that theadjacent channel video is higher than the wantedsound carrier and appears as SIF, then the audiodecoder section detects this frequency as unknownstandard. In that case, the audio may be muted.

This can be solved by forced mode to wanted stan-dard.

– Strong chroma identified as M-system in multistan-dard set with week sound carrier

In auto-detect mode in a multistandard set if thechroma is stronger than the wanted SIF, then the audiodecoder is set to decode 4.5 MHz audio, which is notpresent.

To solve this, M-standard can be excluded in searchmode or manually force the standard to wanted one.

– Audible sound rattle (vertical flyback in audio) when ambient noise is very low (night listening)

If the volume control is in DSP and audio amplifier gainis high, some critical customers can complain aboutvertical rattle in night listening. It is better to use PWMvolume control at the power amplifier, which reducesthe power amplifier gain under low volume conditionsand significantly improves the S/N.

7.2. ESD Hints

– IC fails to receive IR commands

In case the IR receiver is located far away from thechassis and routed to the chassis by wires, it is possi-ble that the wires pickup ESD from EHT and the IRinput can fail. It is better to clamp the IR input line withadditional external diode and a small cap (<100 p) toground.

– Latch-up during ESD tests on I/Os

If the chassis goes to latch up mode during ESD tests,the use of Zener clamping diodes, as last resort, is rec-ommended, if simple RC decoupling fails. It is advis-able to build small Spark gaps (><) near the AV inputsof 0.5 mm space to release some energy.

7.3. Video Issues

– Good signal but no colour tbd

– Switch off spot tbd
