AN5186FB

ICs for TV AN5186FB VIF/SIF IC for car-TV s 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. 33 34 23 (1.00) 12.00±0.20 10.00±0.20 Unit : mm 22 s 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.
