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 invul-

nerable to electric field fluctuation.

• Video output pin for diversity detection (no noise

inverter)

■ Applications

• In-car televisions
