| U3661M Baseband Delay Line (64 ms) Application In TV sets, the integrated baseband delay line circuit is suitable for decoders with color-difference signal outputs Description The integrated delay line circuit U3661M is suitable for all chroma decoders with baseband color-difference outputs. It is suitable for PAL-, SECAM- and NTSC-signals as well. The U3661M contains two separate delay lines for processing (R-Y)-output and (B-Y)-output separately. The delay is performed by internally switched capacitors. On-chip postfiltering avoids the need for external filter components. A summing circuitry combines the information of adjacent TV-lines, thus giving an interpolated sum for the PAL-system, storing preceeding lines for the SECAMsystem and providing a comb-filtered output for NTSC-signals. Due to internally-generated timing, synchronization is easily done by feeding a line-frequent impulse (usually the SC-impulse) to the sync-input of the IC. Features D One line delay time, addition of delayed and non-delayed output signals D Line-locked by the sandcastle pulse D No crosstalk between SECAM color carriers (diaphoty) D Adjustment-free application, VCO without external components D Handles negative or positive color-difference input signals D Comb filtering functions for NTSC color-difference signals D Clamping of ac-coupled input signals [(R-Y) and (B-Y)] D Correction of phase errors in the PAL system "(B-Y) 14 "(R-Y) 16 VRef Clamping Line memory Shift register Clamping S+H S+H LPF + 12 "(B-Y) "(R-Y) Line memory VRef + 11 LPF Bias fSC VDD2 GND2 1 SC detector 3 MHz Control 9 PLL Clock generator VDD1 GND1 3 5 94 8846 10 SC pulse Figure 1.

A1, 17-Jul-96 U3661M 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.
