Stereo decoder The MPX signal is decoded in the stereo decoder part. A PLL is used for the regeneration of the 38 kHz subcarrier. The fully integrated oscillator is adjusted by a digital auxiliary PLL into the capture range of the main PLL. The auxiliary PLL needs an external reference frequency (75.4 kHz) which is provided by the tuner ICs of the NICE family (TEA684x). The required 19 and 38 kHz signals are generated by division of the oscillator output signal in a logic circuit. 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 FMMPX input is the input for the MPX signal from the tuner. The input gain can be selected in three settings to match the input to the RF front-end circuit. A fourth setting is used for weather band mode, which may require a gain of 23.5 dB. A low-pass filter provides the necessary signal delay for FM noise blanking and suppression of high frequency interferences into the stereo decoder input. The output signal of this filter is fed to the roll-off correction circuit. This circuit compensates the frequency response caused by the low-pass characteristic of the tuner circuit with its IF filters. The roll-off correction circuit is adjustable in four 2003 Oct 21 8 Philips Semiconductors Product specification Car radio integrated signal processor TEF6892H MPXRDS signal can be adjusted in four steps, the triggering from the LEVEL signal in three steps. The pilot detector is driven by an internally generated in-phase 19 kHz signal. Its pilot dependent voltage activates the stereo indicator bit and sets the stereo decoder to stereo mode. The same 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. 7.4.2 The trigger pulse for the AM noise blanker is derived from the AM audio signal. The noise spikes are detected by a slew rate detector, which detects excessive slew rates which do not occur in normal audio signals. The sensitivity of the AM noise blanker can be adjusted in four steps. The signal is then decoded in the decoder part. The side signal is demodulated and combined with the main signal to the left and right audio channels. A fine adjustment of the roll-off compensation is done by adjusting the gain of the L-R signal in 16 steps. A smooth mono to stereo takeover is achieved by controlling the efficiency of the matrix by the FMSNC signal from the weak signal processing block. 7.2 7.5 • The average value of the level voltage FM and AM noise blanker • The AM components on the level voltage [Wideband AM (WAM)] • The high frequency components in the MPX signal [Ultrasonic Noise (USN)]. The level voltage is converted to a digital value by an 8-bit analog-to-digital converter. A digital filter circuit (WAM filter) derives the wideband AM components from the level signal. The high frequency components in the MPX signals are measured with an analog-to-digital converter (USN ADC) at the output of the 100 kHz high-pass filter in the MPXRDS path. High cut control and de-emphasis The High Cut Control (HCC) part is a low-pass filter circuit with eight different static roll-off response curves. The cut-off frequencies of these filter curves can be selected by I2C-bus to match different application requirements. The HCC circuit also provides a dynamic control of the filter response. This function is controlled by the AMFMHCC signal from the weak signal processing. The values of these three signals are externally available via the I2C-bus. In the weak signal processing block the three digital signals are combined in a specific way and used for the generation of control signals for soft mute, stereo blend (stereo noise control, FMSNC) and high cut control (AMFMHCC). The signal passes the de-emphasis block with two de-emphasis values (50 and 75 µs), which can be selected via I2C-bus, and is fed to the input selector. 7.4 7.4.1 The sensitivities of the detector circuits (WAM and USN) are adjustable via the I2C-bus. Noise detector Also the start values and the slopes of the control functions soft mute, stereo blend and high cut control can be set via the I2C-bus. FM NOISE DETECTOR The trigger signal for the FM noise detector is derived from the MPXRDS input signal and the LEVEL signal. In the MPXRDS path a four pole high-pass filter (100 kHz) separates the noise spikes from the wanted MPX signal. Another detector circuit triggers on noise spikes on the level voltage. The signals of both detectors are combined to achieve a reliable trigger signal for the noise blanker. AGC circuits in the detector part control the gain depending on the average noise in the signals to prevent false triggering. The sensitivity of the triggering from the 2003 Oct 21 Multipath/weak signal processing The multipath (MPH)/weak signal processing block detects quality degradations in the incoming FM signal and controls the processing of the audio signal accordingly. There are three different quality criteria: The FM/AM switch selects the output signal of the stereo decoder (FM mode) or the signal from the AM input for the noise blanker block. In FM mode the noise blanker operates as a sample and hold circuit, while in AM mode it mutes the audio signal during the interference pulse. The blanking pulse which triggers the noise blanker is generated in the noise detector block. 7.3 AM NOISE DETECTOR Soft mute, stereo blend and HCC are set on hold during the AF updating (quality check of alternative frequency) to avoid an influence of the tuning procedure on the weak signal processing conditions. In AM mode the soft mute and high cut control are available too, the weak signal block is controlled by the average value of the level voltage. 9 Philips Semiconductors Product specification Car radio integrated signal processor 7.6 TEF6892H 7.6.5 Tone/volume control BASS The characteristic of the bass attenuation curves can be set to shelve or band-pass. Four different frequencies can be selected as centre frequency of the band-pass curve. Figures 21 and 22 show the bass curves with a band-pass filter frequency of 60 Hz. The control range is between +14 and −14 dB in steps of 2 dB. The tone/volume control part consists of the following stages: • Input selector • Loudness control • Volume/balance control with muting • Treble control • Bass control 7.6.6 • Fader and output mute The four fader/mute blocks are located at the end of the tone/volume chain. The control range of these attenuators is 0 to −59 dB. The step size is: • Beep generator • NAV input FADER/MUTE • 1 dB between 0 and −15 dB • Output mixer. • 2.5 dB between −15 and −45 dB The settings of all stages are controlled via the I2C-bus. • 3 dB between −45 and −51 dB The stages input selector, loudness, volume/balance, bass, and fader/output mute include the Audio Step Interpolation (ASI) function. This minimizes pops by smoothing the transitions in the audio signal during the switching of the controls. The transition time of the ASI function is programmable by I2C-bus in four steps. • 4 dB between −51 and −59 dB. 7.6.1 7.6.7 The output mixer circuit can add an additional audio signal to any of the four outputs together with the main signal or instead of the main signal. INPUT SELECTOR The additional signal can be generated internally by the beep generator with four different audio frequencies or applied to the NAV input, for instance a navigation voice signal. The input selector selects one of four input sources: • Two external stereo inputs (CD and TAPE) • One external mono input (PHONE) • One internal stereo input (AM/FM). 7.6.2 7.7 LOUDNESS 7.7.1 The output of the input selector is fed into the loudness circuit. Four different loudness curves can be selected via the I2C-bus. The control range is between 0 and −20 dB with a step size of 1 dB; see Figs 16 to 19. 7.6.3 VOLUME/BALANCE 7.7.2 RDS DEMODULATOR RDS DECODER The RDS decoder provides block synchronization, error correction and flywheel function for reliable extraction of RDS or RBDS block data. Different modes of operation can be selected to fit different application requirements. Availability of new data is signalled by read bit RDAV and output pin RDDA. Up to two blocks of data and status information are available via the I2C-bus in a single transmission. The combination of loudness and volume/balance realizes an overall control range of +20 to −79 dB. TREBLE The signal is then fed to the treble control stage. The control range is between +14 and −14 dB in steps of 2 dB. Figure 20 shows the control characteristic. Four different filter frequencies can be selected. 2003 Oct 21 RDS demodulator and decoder The RDS demodulator recovers and regenerates the continuously transmitted RDS or RBDS data stream of the multiplex signal (MPXRDS) and provides the signals clock (RDCL), data (RDDA) and quality (RDQ) for external use or further processing by the integrated RDS decoder. The RDS demodulator uses the reference frequency (75.4 kHz) from the tuner IC and does not need a crystal. The volume/balance control is used for volume setting and also for balance adjustment. The control range of the volume/balance control is between +20 and −59 dB in steps of 1 dB. 7.6.4 BEEP GENERATOR AND NAV INPUT WITH OUTPUT MIXER 10 Philips Semiconductors Product specification Car radio integrated signal processor TEF6892H 8 LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 60134).

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). • 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): There is no soldering method that is ideal for all surface mount IC packages. Wave soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch SMDs. In these situations reflow soldering is recommended. 14.2 – 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. Reflow soldering The footprint must incorporate solder thieves at the downstream end. Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing. • For packages with leads on four sides, 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. Several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. 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 reflow peak temperatures range from 215 to 270 °C depending on solder paste material. The top-surface temperature of the packages should preferably be kept: Typical dwell time of the leads in the wave ranges from 3 to 4 seconds at 250 °C or 265 °C, depending on solder material applied, SnPb or Pb-free respectively. • below 225 °C (SnPb process) or below 245 °C (Pb-free process) A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. – for all BGA and SSOP-T packages 14.4 – for packages with a thickness ≥ 2.5 mm 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. – for packages with a thickness < 2.5 mm and a volume ≥ 350 mm3 so called thick/large packages. • below 240 °C (SnPb process) or below 260 °C (Pb-free process) for packages with a thickness < 2.5 mm and a volume < 350 mm3 so called small/thin packages. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C. Moisture sensitivity precautions, as indicated on packing, must be respected at all times. 14.3 Wave soldering Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. 2003 Oct 21 Manual soldering 55 Philips Semiconductors Product specification Car radio integrated signal processor 14.5 TEF6892H Suitability of surface mount IC packages for wave and reflow soldering methods SOLDERING METHOD PACKAGE(1) WAVE BGA, LBGA, LFBGA, SQFP, SSOP-T(3), TFBGA, VFBGA not suitable suitable(4) DHVQFN, HBCC, HBGA, HLQFP, HSQFP, HSOP, HTQFP, HTSSOP, HVQFN, HVSON, SMS not PLCC(5), SO, SOJ suitable REFLOW(2) suitable suitable suitable not recommended(5)(6) suitable SSOP, TSSOP, VSO, VSSOP not recommended(7) suitable PMFP(8) not suitable LQFP, QFP, TQFP not suitable Notes 1. For more detailed information on the BGA packages refer to the “(LF)BGA Application Note” (AN01026); order a copy from your Philips Semiconductors sales office. 2. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the “Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”. 3. These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account be processed through more than one soldering cycle or subjected to infrared reflow soldering with peak temperature exceeding 217 °C ± 10 °C measured in the atmosphere of the reflow oven. The package body peak temperature must be kept as low as possible. 4. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. 5. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 6. Wave soldering is suitable for LQFP, TQFP and QFP packages with a pitch (e) larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 7.
