Pin configuration Rev. A1: 18.08.1995 Preliminary Information 3 (16) TDA4471 TELEFUNKEN Semiconductors Circuit Description Vision IF amplifier The video IF signal (VIF) is fed through a SAW filter to one of the two VIF inputs (Pins 6–7 or 10–11). The selection of VIF input is controlled by Pin 16 in combination with the standard switch. With a minimal external expense it is possible to switch between two different SAW filters. Both VIF inputs features excellent cross–talk attenuation and an input impedance which is independent from the switching condition. The VIF amplifier consists of three AC–coupled amplifier stages. Each differential amplifier is gain controlled by the automatic gain control (VIF–AGC). Output signal of the VIF amplifier is applied to the FPLL carrier generation and the video demodulator. Tuner– and VIF–AGC At Pin 8 the VIF–AGC charges/discharges the AGC capacitor to generate a control voltage for setting gain of VIF amplifier and tuner in order to keep the video output signal at a constant level. Therefore in case of negative modulated signals (e.g. B/G standard) the sync level of the demodulated video signal is the criterion for a fast charge/discharge of the AGC capacitor. For positive modulation (e.g. L standard) the peak white level of video signal controls the charge current. In order to reduce reaction time for positive modulation, where a very large time constant is needed, an additional black level detector (Pin 17) controls the discharge current in the event of decreasing VIF input signal. The AGC voltage is transferred to an internal control signal, and is fed to the tuner AGC to generate the tuner AGC current at Pin 13 (open collector output). Take over point of the tuner AGC can be adjusted at Pin 12 by a potentiometer or an external DC voltage (from interface circuit or microprocessor). FPLL, VCO and AFC The FPLL circuit (frequency phase locked loop) consists of a frequency and phase detector to generate control voltage for the VCO tuning. In the locked mode the VCO is controlled by the phase detector and in unlocked mode the frequency detector is superimposed. The VCO operates with an external resonance circuit (L and C parallel) and is controlled by internal varicaps. The VCO control voltage is also converted to a current and represents the AFC output signal at Pin 24. With the AFC switch (Pin 21) three operating conditions of the AFC are possible: AFC curve ”rising” or ”falling” and AFC ”off”. A practicable VCO alignment of the external coil is the adjustment to zero AFC output current at Pin 24. At centre 4 (16) frequency the AFC output current is equal to zero. Furthermore, at Pin 16, the VCO centre frequency can be switched for setting to the required L’ value This function is active when ”L mode” is selected by the standard switch. The optional potentiometer at Pin 28 allows an offset compensation of the VCO phase for improved sound quality (fine adjustment). Without a potentiometer (open circuit at Pin 28) this offset compensation is not active. The oscillator signal passes a phase shifter and supplies the in–phase signal (0) and the quadrature signal (90) of the generated picture carrier. Video demodulation and amplifier The video IF signal, which is applied from the gain controlled IF amplifier, is multiplied with the inphase component of the VCO signal. The video demodulator is designed for low distortion and large bandwidth. The demodulator output signal passes an integrated low pass filter for attenuation of the residual vision carrier and is fed to the video amplifier. The video amplifier is realized by an operational amplifier with internal feedback and 8 MHz bandwidth (–3dB). A standard dependent DC level shift in this stage delivers the same sync level for positive and negative modulation. An additional noise clipping is provided. The video signal is fed to VIF–AGC and to the video output buffer. This amplifier with 6dB gain offers easy adaption of the sound trap. For nominal video IF modulation the video output signal at Pin 14 is 2 V (peak to peak value). Sound IF amplifier and SIF–AGC The SIF amplifier is nearly identical with the 3–stage VIF amplifier. Each differential amplifier is gain controlled by the automatic gain control for the sound IF path (SIF– AGC). Output signal of the SIF amplifier is applied to the mixer for FM/NICAM signals and the limiter/ demodulator for AM signals. The SIF–AGC is related to the average level of AM– or FM–carrier and controls the SIF amplifier to provide a constant SIF signal to the AM demodulator and QPS mixer. AM demodulator The alignment–free AM demodulator is realized by a synchronous detector. The modulated SIF signal from the SIF amplifier output is multiplied in phase with the limited SIF signal (AM is removed). The AF signal of the demodulator output is fed to the output amplifier and to the SIF–AGC. For all TV standards with negative video Preliminary Information Rev. A1: 18.08.1995 TDA4471 TELEFUNKEN Semiconductors modulation (e.g. B/G standard) the AF output signal (Pin 27) is switched off by the standard switch. Quasi–Parallel–Sound (QPS) mixer The QPS mixer is realized by a multiplier. The SIF signal (FM or NICAM carrier) is converted to the intercarrier frequency by the regenerated picture carrier (quadrature signal) which is provided from the VCO. The intercarrier signal is fed via an output amplifier to Pin 26. Standard switch To have equal polarity of the video output signal the polarity can be switched in the demodulation stage in accordance with the TV standard. Additional a standard dependent DC level shift in the video amplifier delievers the same sync level. Parallel the correct VIF–AGC is selected for positive or negative modulated VIF signals. In case of negative modulation (e.g. B/G standard) the AM output signal is switched off. If the standard for positive modulation (L standard) is selected the AM demodulator and QPS mixer is active. This condition allows a parallel operation of the AM sound signal and the NICAM–L stereo sound. L’ switch and VIF input selection For positive modulated IF signals (L/L’ standard) Pin 16 works as L’ switch. With a control voltage at Pin 16 the VCO frequency can be switched for setting to the required L’ value (L’ standard). Also a fine adjustment of the L’– VCO centre frequency is possible by a potentiometer. The L’ switch is only active for positive modulated video IF signals (standard switch in L mode). In this mode the video IF input 2 (VIF2) is forced by the standard switch. The possibility to select VIF1 input is given by connecting VIF2 input (pin 10 or 11) via 10 k resistor to ground. If negative modulation (B/G mode) is selected pin 16 operates as an input selection switch for the two VIF inputs. AFC switch The AFC output signal at Pin 24 can be controlled by a switching voltage at Pin 21. It is possible to select an AFC output signal with rising– or falling AFC curve and to switch off the AFC. Internal voltage stabilizer The internal bandgap reference ensures constant performance independant of supply voltage and temperature.

Meet all present and future national and international statutory requirements. 2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems with respect to their impact on the health and safety of our employees and the public, as well as their impact on the environment. It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as ozone depleting substances ( ODSs). The Montreal Protocol ( 1987) and its London Amendments ( 1990) intend to severely restrict the use of ODSs and forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban on these substances. TEMIC TELEFUNKEN microelectronic GmbH semiconductor division has been able to use its policy of continuous improvements to eliminate the use of ODSs listed in the following documents. 1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively 2 . Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental Protection Agency ( EPA) in the USA 3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C ( transitional substances ) respectively. TEMIC can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain such substances. We reserve the right to make changes to improve technical design and may do so without further notice. Parameters can vary in different applications. All operating parameters must be validated for each customer application by the customer. Should the buyer use TEMIC products for any unintended or unauthorized application, the buyer shall indemnify TEMIC against all claims, costs, damages, and expenses, arising out of, directly or indirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
