MT3511 RF MicroDigitizer

Microtuner Inc. has released a RF-to-digital converter that harnesses advanced RF and digital silicon technologies to bring software-defined radio (SDR) to the global automotive industry.

For automotive manufacturers, SDR represents a revolutionary approach to in-vehicle car entertainment, connectivity and multimedia. The MT3511 RF MicroDigitizer enables them to flexibly deliver the most popular consumer features AM/FM, digital radio, CD audio, MP3 playback, navigation, as well as connectivity for iPod, SD card, USB and Bluetooth by using common hardware that is configurable, scalable and upgradable via software. SDR solutions change 'infotainment' business, design and manufacturing models. The technology offers car makers a global radio platform, increased design flexibility, substantial cost-efficiencies and a future-proof migration path to new standards and enhanced features.

The MT3511 is a key front-end component in the SDR architecture. Based on Microtune's next-generation, highly integrated RF MicroDigitizer architecture, the MT3511 is a specialised, automotive-grade RF-to-digital converter optimised to work with generic, high-performance DSPs and multimedia processors to enable the SDR solution.

The device combines the functions of a RF tuner and an advanced ADC in a single miniature chip, it receives and tunes a broadcast signal from a car antenna, and then converts the signal from analogue to digital format for processing in software by a DSP or multimedia processor.

In addition, the converter supports AM/FM, HD Radio technology, digital radio mondiale, and weather band. It replaces multiple hardware-specific components in today's radio sub-system with a generic hardware platform that reduces design complexity, time-to-market, time-to-qualification and costs.

"For decades, leading automotive manufacturers and Tier-1 suppliers have used Microtune radio and TV tuners to migrate compelling consumer-class entertainment to the car," said James Fontaine, President and CEO of Microtune. "We are now introducing a single-chip RF-to-digital converter that will help drive software defined radio throughout the auto industry as a practical mainstream technology. The MT3511 will be a key enabler for the future of in-vehicle audio and multimedia, while it fuels growth and opportunity for our company across the worldwide automotive entertainment markets."
