functional description 3 - 6 tda 6930 wireless components specification, august 1999 3.4 functional description (p-dso-32) n inputs the input signal is distributed via the if-mux to the according amplifier channels. vif-mux normaly vif1 is used for video if input ( filter with no sound carrier). a special mode with a secondary vif input at sif 2 is available. in this case the carrier recovery gets its input signal in any way from sif1. for more information see input selection logic-table in the application circuit section. in the also available intercarrier mode for low cost application, all signals are transferred together via vif1 or vif2 input, depending on input switching logic. sif-mux sif1 input is used for df-sound and carrier recovery ( double channel filter ). for l inverted sideband application sif2 is used instead. amsif input is used for all am sound norms with switchable input filter. n if gain controlled amplifiers the tda 6930x incorporates a video-if demodulation part (vif), a am- sound demodulation part (amsif) and a section for pic-carrier recovery + fm/nicam sif conversion (sif). each path has its own four-stage capaci- tively coupled, gain controlled amplifier. n agcs tuner agc a delayed tuner agc voltage is derived from the vif-agc via an inverting threshold amplifier ( increasing vif input voltage decreases the agcout voltage ). its take over point with positiv control direction is set by means of a external potentiometer. to avoid regulation oszillation the input has a shared characteristic and the output is clamped to min 0.3 v which prevents for coming into gain control inversion at low regulation voltage levels in several tuner application. vif agcs the agc for the video-if-amplifier (vif) has a peak detector for both kinds of modulation. an additional mean value detector will increase the control current for positive modulation if the input signal decreases more than ca. 15 db. in this case a hysteresis keeps the high control current until the mean value increases by ca. 10 db. this and an extremly large sample time pre- vents from agc oszillation with critical signals. sif / amsif agcs the agcs for the am- sound section and pic-carrier recovery +fm/nicam section use envelope detectors with extremely low destortion for the sif amplifiers.
functional description 3 - 7 tda 6930 wireless components specification, august 1999 they have a quick charge circuit which increases the charge current by a factor of 1500 if the mean value of the signal increases by more than 10 db. the time constants of the agcs can be set by the according external capac- itor. n fpll fpll carrier recovery high perfomance in terms of fm sound, digital sound and videotext is obtained by means of a combined path for carrier recovery and fm/nicam sif (qpt). the input signal for this section is derived from the qpt sif i/ii input to overcome nyquist slope distortions in all cases. for l-applications the vco frequency is switched internally, thus no external tank circuit switching is necessary. adjustment of the tank circuit (only necessary for the afc) is achieved by aligning the afc voltage to a certain value except in l- mode. in l-mode the afc needs to be adjusted via control voltage at pin ssw2. apc for best video demodulation a phase locked clean carrier is needed. due to differences in the filter and amplifier characteristics of the amplifier channels it is necessary to align the phase of the recovered carrier to the incoming sig- nal of vif port . the possible phase control margin of the therefore used apc is +180 to -180 . for best performance 2 external low pass capacitors are added at the p- dso-32 package. in this case the apc is extremly stable at carrier zero time and over modulation. this feature is not available in the less than 32 pin packages . vco the vco consists of a temperature compensated stacked symmetrical ecl multivibrator and devider by 2 . the main tank circuit is aligned to twice of the recovery frequency. all internal signals are of symmetrical ecl type. this is necessary for small amplitudes with high temperature stability and low oscillator radiation. n video demodulation + output video if demodulation a real synchronous demodulator receives an inphase carrier via the auto- matic phase control (apc) from the fpll. thus, low differential phase and gain, high intermodulation ratio und good impuls response is achieved with- outh any aligment. n df-mixer / fm sound conversion the sif-sound/pic-carrier section gets its input signal from sif1 except in l-nicam mode, then input sif 2 is active. the sif- signal is mixed with the 90 -carrier from the fpll to generate the 2. sound if at the according output (df). this output is always active except in mac standard, there both sound outputs are off.
functional description 3 - 8 tda 6930 wireless components specification, august 1999 n am-audio sound demodulation the am-sound section uses the envelope detector of the agc to demodu- late the am sound signal. an optimized special am-sound demodulator and the envelope detector garantee an extremely low af output destortion. in case of l or l standard the am-af output is active, in other standards this output is inactive. according to the standard switches fm/nicam and/or am processing is per- formed. n afc + adjust the afc consists of a high inpedance input comparator who gets its control voltage from the loopfilter / vco charge pump capacitor. its ota output volt- age swing and gain can be controlled via the necessary external load resis- tors the adjust is controlled by norm switch inputs and is only aktive in l mode. the operation is performed by controlling the reference input voltage of the afc comparator. n switches the internal i 2 l norm switch decoding logic is buffered by pnp comparator interfaces with hysteresis. therefore the input signal voltage margin at ssw1 and ssw2 is 0 - vcc n voltage reference the reference voltage is performed by a temperature compensated band- gap structure with extremly low noise and high ripple rejection (pssr). the reference voltage distribution is done by 3 buffer amplifiers with extremly high ripple rejection (pssr).
