The Microtune MT2067 is an automotive-grade TV tuner engineered to provide stable TV reception for passengers in vehicles travelling at top speeds along the motorway.

The company said it enables car makers to improve performance, increase reliability and minimise total RF systems costs when adding real-time broadcast TV to rear-seat entertainment options.

At 7mm x 7mm, the MT2067 chip allows car makers to replace conventional bulky modules with advanced silicon TV tuner chips.

It enables customers to design multi-standard global TV receiver platforms and supports worldwide analogue and digital terrestrial standards that include NTSC, PAL, SECAM, DVB-T, DVB-H, ISDB-T, DTMB, ATSC and ATSC-M/H.

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, strong signal behaviour and improved channel selectivity.

The MT2067 is also engineered to receive 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.

The MT2067 is a dual-conversion single-chip tuner that supports the RF frequency range from 48 to 862MHz.

An integrated low-noise amplifier ensures sensitivity, while Microtune’s Cleartune filter technology limits interference from strong undesired channels.

The MT2067 tuner automatically controls the RF gain, depending on the receiving conditions.

In order to support hybrid-receiver designs, it provides two intermediate-frequency (IF) outputs, one for connecting a digital TV demodulator and a second one to connect an analogue TV demodulator.

As with Microtune’s other automotive products, the MT2067 is engineered to operate in the harsh vehicular environment.

It supports temperatures from -40 to +85C, and is designed to be qualified according to the requirements of the Automotive Electronics Council (AEC) Q100.

The MT2067 requires few quality-sensitive supporting components.
