TDA4454 TELEFUNKEN Semiconductors Multistandard VIF Amplifier and PLL Demodulator Application Monolithic integrated circuit for vision IF signal processing in multistandard TV and VTR sets. Description This multistandard video IF processing circuit with PLL picture carrier regeneration gives a high performance of linear video demodulation. The IF signal is internally fed via a 3-stage controlled wideband amplifier to the video demodulator and the phase detector. The phase detector compares the phase of IF signal (0°) with the output signal of the VCO (90°) and sets the VCO frequency accordingly. A lock detector switches the PLL loop filter according to the state of the PLL (locked-PLL slow, unlocked-PLL fast). A second output of the VCO (0°) provides the reference carrier for the video demodulator. The polarity of the demodulator can be inverted by the standard switch (Pin 10), so that negative or positive modulated IF signals are always available with the same polarity at the demodulator output. The demodulated video signal is filtered, amplified and fed via an interference limiter to the video output (Pin 6). The standard switch also determines the clamp level of the video amplifier and the required IF-AGC mode. In the standard B/G mode the sync peak value is the criterion for a fast charge and discharge. In the standard L mode on the other hand, fast AGC action is achieved by charging at peak white level and discharging by the averaged video signal (time constant on Pin 7). The response level for discharge has a hysteresis. In the D2MAC mode a similar function is applied to achieve the AGC, but with different threshold levels. An overload detector prevents the PLL becoming unlocked by large IF input signals. To achieve a delayed tuner-AGC action, the current output (Pin 3) can be adjusted with a resistor at Pin 2. Features D Suitable for standard B/G, L and D2MAC, processes negative and positive modulated IF-signals with equal polarity of the output signal D High performance video demodulator with PLL picture carrier regeneration D Extended video bandwidth (12 MHz) for the demodulation of amplitude modulated MAC-signals D Standard B/G: AGC acting on the sync peak pulse D Standard L: fast AGC acting on peak white level with average value controlled capacitor discharge and reference hysteresis D D2MAC: fast AGC acting on peak level with controlled capacitor discharge D Output for delayed tuner-AGC, take over point adjustable D High input sensitivity D Ultra white and ultra black limiting D Supply voltage range 6.8 to 13 V D Low power consumption D ESD protection Package Options Case: 16-pin DIL plastic Rev.

A1: 04.05.1995 TELEFUNKEN Semiconductors TDA4454 Ozone Depleting Substances Policy Statement It is the policy of TEMIC TELEFUNKEN microelectronic GmbH to 1. 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.
