Pin configuration Circuit description Vision IF amplifier The video IF signal (VIF) is fed through a SAW filter to the VIF input (Pin 5–6). 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. demodulated video signal is the criterion for a fast charge/ discharge of the AGC capacitor. The control voltage (AGC voltage at Pin 7) is transferred to an internal control signal and fed to the tuner AGC to generate the tuner AGC current at Pin 12 (open collector output). Take over point of the tuner AGC can be adjusted at Pin 11 by a potentiometer or an external DC voltage (from interface circuit or microprocessor). VIF–AGC and adjustable tuner AGC At Pin 7 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 the sync level of the 2 (9) Preliminary Information Rev. A1: 15.08.1995 U4460BG TELEFUNKEN Semiconductors FPLL, VCO and AFC Video demodulation and amplifier 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 23. 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). 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 13 is 2 V (peak to peak value). A practicable VCO alignment of the external coil is the adjustment to zero AFC output current at Pin 23. At centre frequency the AFC output current is equal to zero. The optional potentiometer at Pin 27 allows an offset compensation of the VCO phase for improved sound quality (fine adjustment). Without a potentiometer (open circuit at Pin 27) 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. 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.
