ICs for TV AN5186FB VIF/SIF IC for car-tv Overview The AN5186FB is a VIF/SIF signal processing IC for in-car television. The video and sound are completely separated by the adoption of split carrier method. Also, high performance and high function have been realized by the incorporation of in-car circuits such as soft mute and SD. Features Split carrier method sound detection circuit Electric field detection and band detection type soft mute and SD Multipath detection circuit VIF uses quasi-synchronous detection which is invulnerable to electric field fluctuation. Video output pin for diversity detection (no noise inverter) Applications In-car televisions Package QFP044-P-1010F Publication date: June 2006 SDB00003CEB 1

Any applications other than the standard applications intended. (4) The products and product specifications described in this book are subject to change without notice for modification and/or improvement. At the final stage of your design, purchasing, or use of the products, therefore, ask for the most up-to-date Product Standards in advance to make sure that the latest specifications satisfy your requirements. (5) When designing your equipment, comply with the range of absolute maximum rating and the guaranteed operating conditions (operating power supply voltage and operating environment etc.). Especially, please be careful not to exceed the range of absolute maximum rating on the transient state, such as power-on, power-off and mode-switching. Otherwise, we will not be liable for any defect which may arise later in your equipment. Even when the products are used within the guaranteed values, take into the consideration of incidence of break down and failure mode, possible to occur to semiconductor products. Measures on the systems such as redundant design, arresting the spread of fire or preventing glitch are recommended in order to prevent physical injury, fire, social damages, for example, by using the products. (6) Comply with the instructions for use in order to prevent breakdown and characteristics change due to external factors (ESD, EOS, thermal stress and mechanical stress) at the time of handling, mounting or at customer's process. When using products for which damp-proof packing is required, satisfy the conditions, such as shelf life and the elapsed time since first opening the packages.
