Technical content
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. n 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 invul- nerable to electric field fluctuation.
- Video output pin for diversity detection (no noise inverter) n Applications
