Infotainment


Automotive infotainment systems provide distribution and playback of audio and video signals. They must frequently display the operating status of the vehicle and external driving information, such as visual navigation directions, location, informational messages, and environmental data. The feature sets required by automotive infotainment systems have expanded greatly over the last decade. We offer a wide range of analog ICs that significantly enhance the performance of these popular automotive systems.



Applications


Power Management for Infotainment

Power management ICs for automotive infotainment need to offer high switching frequencies to minimize the solution size. In addition they should minimize electro-magnetic interference (EMI). Typically located in the Radio Head Unit (RHU) and entertainment control modules, these ICs are usually attached directly to the main battery. They should, therefore, be able to handle high input voltages (>36V) and to reliably survive load dump events through the life of the vehicle.

Display Power

Liquid crystal displays of many sizes are finding their way into the center console of the modern automobile. These displays require brightness controls with a wide dimming range and must operate in a low EMI environment. Our display power ICs and backlight drivers have been designed with this in mind.

Low-Noise Amplifiers (LNAs)

Our low-noise amplifiers (LNAs) with adjustable gain control capture and process signals at the antenna. We offer solutions for AM/FM/DAB broadcast radio and GPS/GNSS satellite navigation.

RF Tuners/Receivers

We deliver high-integration radio, navigation, and television tuners and receivers for your vehicle infotainment system design.

DAB or Sirius XM tuners convert digital radio signals to digital I/Q output with low power consumption.  Digital TV tuners convert broadcast ISDB-T and DVB-T signals to a low-IF signal using a broadband I/Q downconverter. The operating frequency range covers the VHF and UHF broadcast TV bands from 90MHz to 862MHz.

For navigation systems, our complete GPS, GLONASS, Compass, and Galileo front-end IC (MAX2769B) simplifies navigation system design.

Video Distribution

Our GMSL serializer-deserializer (SerDes) high-speed video links provide an optimal solution for connecting head-unit video data to rear seat entertainment consoles.

Mobile Device Charging and Protection

Today most vehicle owners have a mobile smart device or transport people who do. These low-power devices frequently become personal entertainment or communication equipment during the drive. Thus, battery charging outlets are becoming standard equipment in most vehicles.
