2.2. Sound Processing 2.2.1. Analog Sound Input input pins ANA_IN1+, ANA_IN2+, ANA_IN- offer possibility connect different sound (SIF) sources 34x1G. analog-to-digital conversion preselected sound signal done A/D-converter. analog automatic gain circuit (AGC) allows wide range input levels. highpass filters formed coupling capacitors pins ANA_IN1+ ANA_IN2+ Section "Appendix Application Circuit" page sufficient most cases suppress video components. Some combinations filters sound mixer ICs, however, show large picture components their outputs. this case, further filtering recommended.

2.4. Source Selection Output Channel Matrix Source Selector makes possible distribute source signals (one demodulator source channels, SCART, input) desired output channels (loudspeaker, headphone, etc.). input output signals processed simultaneously. Each source channel identified unique source address. each output channel, sound mode sound sound stereo, mono means output channel matrix. Automatic Sound Select output channel matrix stay fixed stereo (transparent) demodulated signals. output level [dBr]
input level [dBr] Fig. 2-4: Simplified characteristics
2.5. Audio Baseband Processing 2.5.1. Automatic Volume Correction (AVC) Different sound sources (e.g. terrestrial channels, channels, SCART) fairly often have same volume level. Advertisements during movies usually have higher volume level than movie itself. This results annoying volume changes. Automatic Volume Correction (AVC) solves this problem equalizing volume level. prevent clipping, AVC's gain decreases quickly dynamic boost conditions. suppress oscillation effects, gain increases rather slowly level inputs. decay time programmable means register (see page 34). input signals ranging from dBr, maintains fixed output level dBr. Fig. shows output level versus input level. prescale volume registers level corresponds full scale input/output. This SCART input/output Vrms Loudspeaker output Vrms
2.5.2. Loudspeaker Headphone Outputs following baseband features implemented loudspeaker headphone output channels: bass/treble, loudness, balance, volume. square wave beeper added loudspeaker headphone channel. loudspeaker channel additionally performs: equalizer (not simultaneously with bass/treble), spatial effects, subwoofer crossover filter.

2.6. Virtual Surround System Application Tips 2.6.1. Sweet Spot Good results only obtained rather close area along middle axis between loudspeakers: sweet spot. Moving away from this position degrades effect.
2.6.3. Loudspeaker Requirements loudspeakers used their positioning inside will greatly influence performance virtualizer. algorithm works with direct sound path. Reflected sound waves reduce effect. it's most important have much direct sound possible, compared indirect sound. obtain approval set, Dolby Laboratories require mounting loudspeakers front set. Loudspeakers radiating side will produce convincing effects. Good directionality loudspeakers towards listener optimal. virtualizer specially developed implementation sets. Even rather small stereo TV's, sufficient sound effects obtained. small sets, loudspeaker placement should side CRT; large screen sets 16:9 sets), mounting loudspeakers below acceptable (large separation preferred, frequency speakers should outmost avoid cancellation effects). Using external loudspeakers with large stereo base will create optimal effects. loudspeakers should able reproduce wide frequency range. most important frequency range starts from ranges kHz. Great care taken with systems that common subwoofer: single loudspeaker cannot reproduce virtual sound locations. crossover frequency must lower than
2.6.2. Clipping test Dolby Labs, very important have clipping effects even with worst case signals. That Vrms input signal clip. SCART Input Prescale register values 19hex (25dec) lower (see SCART Input Prescale page 31). Test signals: sine sweep with VRMS; only, only, equal phase, anti phase. Listening tests: Dolby Trailers (train trailer, city trailer, canyon trailer.)
2.6.4. Cabinet Requirements During listening tests Dolby Laboratories, resonances cabinet should occur. Good material check resonances Dolby Trailers other dynamic sound tracks.

2.8. Interface possible route external coprocessor special effects, like surround processing sound field processing. Routing done with each input source output channel inputs outputs. possible interface formats supported: SONY format: I2S_WS changes word boundaries. PHILIPS format: I2S_WS changes I2S_CL period before word boundaries. interface consists five pins: I2S_DA_IN1, I2S_DA_IN2: input, four channels (two channels line, 2*16 bits) sampling cycle kHz) transmitted. I2S_DA_OUT: output, channels (2*16 bits) sampling cycle kHz) transmitted. I2S_CL: Gives timing transmission serial data (1.024 MHz). I2S_WS: I2S_WS word strobe line defines left right sample. 34x1G normally serves master interface. this case, clock word strobe lines driven 34x1G. slave mode, these lines input 34x1G master clock synchronized times I2S_WS rate kHz). NICAM operation possible this mode. options means MODUS register (see page 28). precise timing diagram shown Fig. 4-26 page
2.7. SCART Signal Routing 2.7.1. SCART SCART Select SCART Input Select SCART Output Select blocks include full matrix switching facilities. design with four pairs SCART-inputs pairs SCART-outputs, external switching hardware required. switches controlled user register (see page 40).
2.7.2. Stand-by Mode 34x1G switched first pulling STANDBYQ then (after delay) switching 5-V, keeping power supply (`Standby'-mode), SCART switches maintain their position function. This allows copying from selected SCART-inputs SCART-outputs set's stand-by mode. case power starting from stand-by (switching supply, RESETQ going high later), internal registers except register (page reset default configuration (see Table page 22). reset position register becomes active after first transmission into Baseband Processing part (subaddress 12hex). transmitting register first, reset state redefined.

Interface ASTRA Digital Radio System (ADR), 3401G, 3411G 3451G performs preprocessing such carrier selection filtering. 3-line ADR-bus, resulting signals transferred 3510A coprocessor, where source decoding performed. prepared upgrade with additional board, following lines 34x1G should provided feature connector: AUD_CL_OUT I2S_DA_IN1 I2S_DA_IN2 I2S_DA_OUT I2S_WS I2S_CL ADR_CL, ADR_WS, ADR_DA more details, please refer 3510A data sheet.
2.11. Clock Oscillator Crystal Specifications 34x1G derives internal system clocks from 18.432-MHz oscillator. NICAM I2SSlave mode, clock phase-locked corresponding source. Therefore, possible NICAM I2S-Slave mode same time. proper performance, clock oscillator requires 18.432-MHz crystal. Note that phase-locked modes (NICAM, I2S-Slave), crystals with tighter tolerance required. Remark using crystal: External capacitors each crystal ground required. They necessary tuning open-loop frequency internal stabilizing frequency closed-loop operation. higher capacitors, lower resulting clock frequency. nominal free running frequency should match 18.432 closely possible. Clock measurements should done AUD_CL_OUT. This must activated this purpose (see Table page 28).
2.10.Digital Control Pins Status Change Indication static level digital input/output pins D_CTR_I/O_0/1 switchable between HIGH I2C-bus means register (see page 40). This enables controlling external hardware switches other devices I2C-bus. digital input/output pins high impedance means MODUS register (see page 28). this mode, pins used input. current state read STATUS register (see page 29). Optionally, D_CTR_I/O_1 used interrupt request signal controller, indicating changes read register STATUS. This makes polling unnecessary, interactions reduced minimum (see STATUS register page MODUS register page 28).
