Microtune has released what it claims as a first-of-its-kind tuner chip for high-speed in-car TV. The MicroTuner MT2067 is a world-standard, automotive-grade TV tuner engineered to deliver superior, stable TV reception for passengers in vehicles traveling at top speeds along the autobahn or highway. Microtune says the chip enables automakers to improve performance, increase reliability and minimise total RF systems costs when adding real-time broadcast TV to increasingly popular rear-seat entertainment options.

At 7 x 7 millimeters, the miniature MT2067 chip allows auto makers to replace conventional bulky modules with advanced silicon TV tuner chips. In addition to its very low profile, the MT2067 enables customers to design multi-standard global TV receiver platforms. It supports worldwide analogue and digital terrestrial standards that include NTSC, PAL, SECAM, DVB-T, DVB-H, ISDB-T, DTMB, ATSC and ATSC-M/H.

James A. Fontaine, President and CEO of Microtune said, "As with our recently announced MT1119 antenna amplifier, the MT2067 is part of a new portfolio of highly integrated RF silicon technology products targeted for the automotive market. It is engineered specifically to meet the complex, rigorous technical, operating and qualification requirements of our automotive customers, providing an advanced electronics solution as the industry strives to deliver competitive entertainment value and options to ever-more demanding consumers."

High-speed in-car TV puts severe radio frequency (RF) demands on the tuner, and the MT2067 is engineered to solve the technical challenges associated with receiving analogue and digital TV signals in a constantly changing, fast-moving environment. It is optimised for excellent sensitivity, superior strong signal behaviour and improved channel selectivity, the three most critical technical parameters for mobile TV reception.

The MT2067 is also engineered to deliver no-compromise performance for receiving weak signals and signals packed in dense, urban signal environments. It offers Microtune's spur-avoidance technology, which enables high-performance in multi-tuner diversity architectures by preventing interference between tuners.
