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. • V ideo output pin for diversity detection (no noise inverter) 44 1 (1.00) 0.80 11 0.35+0.10 –0.05 12 1.95±0.20 10.00±0.20 12.00±0.20 (1.00) 0.15 –0.05 +0.10 Seating plane 0.10±0.10 0° to 10° 0.50±0.20 QFP044-P-1010C s Applications • In-car televisions 1 AN5186FB s Block Diagram SD out GND3 VCC3 VREF ICs for TV 33 32 31 30 29 28 27 26 25 24 23 RF AGC 34 delay 35 36 37 OSC Buffer amp. 1st limiter Regulator 22 GND2 2nd limiter Regulator V cont. detector Mixer SD detector V cont.
