7 FUNCTIONAL DESCRIPTION

7.1 Stereo decoder

The MPX input is the null-node of an operational amplifier with internal feedback resistor. Adapting the stereo decoder input to the level of the MPX signal, coming from the FM demodulator output, is realized by the value of the input series resistor RIN. To this input a second source (AM detector output) can be fed by current addition.

The input amplifier is followed by an integrated 4th order Bessel low-pass filter with a cut-off frequency of 80 kHz. It provides necessary signal delay for FM noise blanking and damping of high frequency interferences coming to the stereo decoder input.

Output of this filter is fed to the soft mute control circuitry, the output is voltage to current converted and then fed to phase detector, pilot detector and pilot canceller circuits, contained in the stereo decoder PLL block. For regeneration of the 38 kHz subcarrier, a PLL is used. The fully integrated oscillator is adjusted by means of a digitalauxiliaryPLLintothecapture range of the main PLL. The auxiliary PLL needs an external reference frequency (75.4 kHz) which is provided by the TEA6840H. The required 19 and 38 kHz signals are generated by division of the oscillator output signal in a logical circuitry. The 19 kHz quadrature phase signal is fed to the 19 kHz phase detector, where it is compared with the incoming pilot tone. The DC output signal of the phase detector controls the oscillator (PLL).

The pilot presence detector is driven by an internally generated in-phase 19 kHz signal. Its pilot dependent DC output voltage is fed to a threshold switch, which activates thepilotindicatorbitandturnsthestereodecoderto stereo operation. The same DC voltage is used to control the amplitude of an anti-phase internally generated 19 kHz signal. In the pilot canceller, the pilot tone is compensated by this anti-phase 19 kHz signal.

The pilot cancelled signal is fed to the matrix. There, the side signal is demodulated and combined with the main signal to left and right audio channel. Compensation for roll-off in the incoming MPX signal caused by IF filters and FM demodulator is typically realized by an external compensation network at pin 57, individual alignment is achieved by I2C-bus controlled amplification of the side signal (DAA). A smooth mono to stereo takeover is achieved by controlling the efficiency of the matrix with help of the SNC peak detector.

TEA6880H

The matrix is followed by the FM noise suppression gates, which are combined with FM single poles and High Cut Control (HCC). The single pole is defined by internal resistors and external capacitors. From the gate circuits audio is fed to the switchable de-emphasis, where the demodulated AM stereo signal can be fed in. After de-emphasis the signal passes to the output buffers and is fed to the radio input of the source selector. For HCC, the time constant of the single pole contained in the output buffer can be changed to higher values. This function is controlled by an average detector contained in the multipath and fading detector.

7.2 FM noise blanker

The input of the ignition noise blanker is coupled to the MPXRDS (pin 55) input signal and to the IF level input (pin 3). Both signals are fed via separate 120 kHz filters and rectifiers to an adder circuit. The output signal of the adder circuit is fed in parallel to the noise detector and the interference detector. The noise detector is a negative peak detector. Its output controls the trigger sensitivity (prevention to false triggering at noisy input signals) and the gain of the MPX high-pass filter. The output of the interferencedetector,whenreceivingasteeppulse,firesa monoflop, contained in the pulse former circuitry. The time constantofthemonoflopis defined by aninternalcapacitor and its output activates the blanking gates in the audio.

7.3 AM noise blanker

The AM noise blanking pulse is derived from the AM audio signal which is fed into pin 53 with the help of a peak-to-averagecomparator. The blanking time is set by a pulse former with external capacitor. The blanking pulse is fed to the gate in the AM audio path and out to pin AMHOLD to operate the gate built into the external AM stereo processor.

7.4 Multipath/fading detection and weak signal control

For FM signal quality dependent controls there is built-in a combinationofsixdetectorsdrivenbythelevelinformation direct, by the AC components on the level via a 20 kHz band-pass filter (AM wideband) or the high notes present at the FM demodulator output via a 60 kHz high-pass filter (ultrasonic noise). The relation between DC level and the AC components is programmable by the I2C-bus (2 bits each). Output of level buffer, AM wideband detector and ultrasonic noise detector are analog-to-digital converted and readable by the I2C-bus.

Page 11

Up-level Car radio Analog Signal Processor (CASP)

For the time of fast RDS updating soft mute, SNC and HCC can be put on hold and the AM wideband peak detector and the ultrasonic noise peak detector are put on reset by a switch signal delivered from the TEA6840H via pin 51 (FMHOLD).

The six separate detecting circuits are:

1. The AM wideband noise peak detector is driven from a 20 kHz band-pass filter connected to the level buffer output. The time constant is defined by an external capacitor at pin 45 (TWBAM2). The output voltage of the detector is analog-to-digital converted by 3-bit.

2. The AM wideband noise average detector is driven from a 20 kHz band-pass filter connected to the level buffer output. The time constant is defined by an external capacitor at pin 63 (TWBAM1). The output of the detector is connected to the Stereo Noise Control (SNC) circuit.

3. The ultrasonic noise peak detector is driven from a 60 kHz high-pass filter connected to the MPX signal from pin 55 (MPXRDS). The time constant is defined byanexternalcapacitorat pin 46 (TUSN2). Theoutput voltage of the detector is analog-to-digital converted by 3-bit.

4. The ultrasonic noise average detector is driven from a 60 kHz high-pass filter connected to the MPX signal from pin 55 (MPXRDS). The time constant is defined byanexternalcapacitorat pin 64 (TUSN1). Theoutput of the detector is connected to soft mute control and stereo noise control circuits.

5. For soft mute and high cut control purposes an average detector with externally defined time constant (TMUTE, pin 54) is provided. The detector is driven by level output only. Soft mute as well as high cut control can be switched off by the I2C-bus.

6. The stereo noise control peak detector with externally defined time constant (TSNC, pin 56) is driven by DC level output, AM wideband and ultrasonic noise outputs. It provides the stereo blend facility (SNC). Startingpoint and slope of stereo blend can be chosen by the I2C-bus controlled reference voltage.

TEA6880H

7.5 Tone/volume control

The tone/volume control part consists of the following functions:

• Source selector

• Loudness

• Volume 1

• Treble

• Bass

• Volume 2

• Rear Seat Audio (RSA) selector

• Chime adder

• Analog step interpolation

• Audio blend control.

The stages loudness, volume 1, bass, and volume 2 include the Analog Step Interpolation (ASI) function. This minimizes pops by smoothing out the transitions in the audio signal during switching. The transition time is I2C-bus programmable in a range of 1 : 24 in four steps.

The stages loudness, volume 1, and volume 2 also have the Audio Blend Control (ABC) function. This minimizes pops by automatically incrementing the volume and loudnesscontrolsthrougheachstep between theirpresent settings and the new settings. The speed of the ABC function is correlated with the transition time of the ASI function.

All stages are controlled via the I2C-bus.

7.5.1 SOURCE SELECTOR

The source selector allows the selection between 6 sources:

• 2 external stereo inputs (ALI, ARI, BLI and BRI)

• 1 external symmetrical stereo input (CLIP, CRIP and

CCOM)

• 1 external symmetrical mono input (MONOP and

MONON)

• 1 internal stereo input (AM/FM)

• 1 chime/diagnostic mono input (CHIME).

Via the chime/diagnostic mono input a chime input signal can be sent to any audio output, at any volume level.

7.5.2 LOUDNESS

The output of the source selector is fed into the loudness circuit via the external capacitors C LOPI) and C the external circuits for the left and the right channel only a bass boost or bass and treble boost is available. With the external circuits shown in Figs 13 and 15 the curves from Figs 14 and 16 will be obtained (without influence of C respectively C

7.5.3 VOLUME 1

The volume 1 control follows behind the loudness circuit. The control range of volume 1 is between +20 and −36 dB in steps of 1 dB.

7.5.4 TREBLE

The output signal of the volume 1 control is fed into the treble control stage. The control range is between +14 and −14 dB in steps of 2 dB. Fig.20 shows the control characteristic with external capacitors of 10 nF.

7.5.5 BASS Thebasscontrolisthenext stage. The characteristic of the

bass curves depends upon the external circuits at pins LBO/LBI (left channel) and RBO/RBI (right channel) and also upon the setting of BSYM bit (MSB of the bass control byte). With BSYM = 1, an equalizer characteristic and with BSYM = 0, a shelving characteristic is obtained. Figures 17 and 18 show the bass curves with an external circuit of 2 × 220 nF and R = 3.3 kΩ for each channel with different values for BSYM. Figure 19 shows the bass curves with an external capacitor of 47 nF for each channel and BSYM = 0, for boost and cut.

7.5.6 VOLUME 2 The four volume 2 blocks are located at the end of the

tone/volume control. In addition to volume control (same settings as volume 2) also the balance and fader functions are performed by individual attenuation offsets for the four attenuators. The control range of these attenuators is 56 dB in steps of 1 dB and additional the steps −58.5 dB,

−62 dB, −68 dB, and a mute step.

7.5.7 RSA SELECTOR The RSA selector provides the possibility to select an

alternative source for the rear channels. In this event rear channels are only controlled by volume 2 function.

7.5.8 CHIME ADDER With the chime adder circuit the chime input signal can be

summed with the left front and/or right front audio, or be turned off.

14 SOLDERING

14.1 Introduction to soldering surface mount packages

Thistextgivesaverybriefinsighttoacomplex technology. A more in-depth account of soldering ICs can be found in our

“Data Handbook IC26; Integrated Circuit Packages”

(document order number 9398 652 90011). There is no soldering method that is ideal for all surface

mount IC packages. Wave soldering is not always suitable for surface mount ICs, or for printed-circuit boards with high population densities. In these situations reflow soldering is often used.

14.2 Reﬂow soldering

Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied totheprinted-circuitboardbyscreenprinting,stencillingor pressure-syringe dispensing before package placement.

Several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method.

Typical reflow peak temperatures range from 215 to 250 °C. The top-surface temperature of the packages should preferable be kept below 230 °C.

TEA6880H

If wave soldering is used the following conditions must be observed for optimal results:

• Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave.

• For packages with leads on two sides and a pitch (e): – larger than or equal to 1.27 mm, the footprint

longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board;

– smaller than 1.27 mm, the footprint longitudinal axis

must be parallel to the transport direction of the printed-circuit board.

The footprint must incorporate solder thieves at the downstream end.

• Forpackageswithleadsonfoursides, the footprint must be placed at a 45° angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners.

During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured.

Typical dwell time is 4 seconds at 250 °C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications.

14.3 Wave soldering

Conventional single wave soldering is not recommended forsurfacemountdevices(SMDs)orprinted-circuitboards with a high component density, as solder bridging and non-wetting can present major problems.

To overcome these problems the double-wave soldering method was specifically developed.

2000 May 08 85

14.4 Manual soldering

Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 °C.

When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C.
