| U3660M-B Baseband Delay Line (64 ms) Description The U3660M is an integrated baseband delay line circuit. It provides a delay of 64 ms for the color difference signals, (R-Y) and (B-Y), in multi-standard TVs. Features D One line delay time, addition of delayed and nondelayed output signals D Adjustment-free application, VCO without external components D Line-locked by the sandcastle pulse D No crosstalk between SECAM colour carriers (diaphoty) D Handles negative or positive colour-difference input signals D Comb filtering functions for NTSC colour-difference signals D Clamping of ac-coupled input signals [(R-Y) and (B-Y)] D Correction of phase errors in the PAL system Block Diagram Ref 13 Bias "(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 3 MHz fsc V DD2 GND2 1 SC detector Control 9 V DD1 GND1 Clock generator PLL 3 5 10 94 8223 SSC pulse Figure 1.

A2, 13-Dec-96 U3660M-B 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.
