Microtune's New RF Silicon and Systems Products Enable In-Car Digital Entertainment and Wireless Connectivity for Global Automakers

9/17/2002 - Reinforcing its commitment to deliver advanced radio frequency (RF) solutions for automakers, Microtune® unveiled three products targeted to the emerging in-car entertainment and personal telematics markets. The products-the MT1110 broadband amplifier chip, the MT7402 in-car digital TV tuner and MT0755A BluetoothTM OneChip-provide cost-optimized core components that enable global car manufacturers to deliver digital video and multimedia, mobile Internet access and hands-free communications to mainstream drivers and passengers.

The silicon and subsystems products are currently being deployed in automotive applications, and Microtune plans to showcase them in customer solutions in its booth (Number 1342) during the upcoming Convergence Trade Show, October 21-23, at the COBO Conference Center in Detroit, MI.

"Consistent with our strategy, Microtune's goal is to grow our automotive business by supplying a multi-product portfolio of innovative RF silicon and systems solutions," said Douglas J. Bartek, Chairman and CEO of Microtune. "By leveraging our broadband and Bluetooth technologies with our extensive automotive systems experience, we are positioned to develop new products qualified to meet the specific performance requirements of the in-vehicle environment. At the same time, we enable automakers to deploy leading-edge, market-proven RF technologies that accelerate the introduction of advanced communications and entertainment electronics into their cars."

As companions to Microtune's world-class AM/FM, analog car TV, multimedia and telematics tuners, Microtune's three automotive products provide the complementary RF components required to deliver data, video and voice to the vehicle via RF or wireless networks.

MT7402 Digital TV Tuner for In-Car TV Entertainment
The new MT7402 MicroModule is a complete DVB-T TV subsystem enabling in-car TV and multimedia applications. Designed for high-end, multiple-tuner configurations, the MT7402 is targeted for worldwide automakers that require a digital or hybrid analog/digital solution.

The MT7402 incorporates the tuner, the SAW filter and Microtune's MT1230 intermediate frequency variable-gain amplifier in a production-ready, pre-tested solution. Optimized for excellent sensitivity and superior adjacent channel and multipath suppression, the MT7402 offers robust performance, producing clean sound, pictures and data with minimal noise and interference. Packaged in a compact, highly integrated module, the MT7402 offers maximum design flexibility. It permits direct interface to the digital demodulator, such as Microtune's MT8872 DVB-T demodulator. At the same time, the device features the lower profile, expanded temperature range and ruggedized electronics required for the automotive environment.

MT1110 Broadband Amplifier
The MT1110 RF Broadband Amplifier is a high-performance, low-power integrated circuit (IC) that improves the quality of RF signals delivered to in-vehicle navigation or entertainment systems. Functioning as a complement to Microtune's automotive TV tuners, the MT1110 boosts and conditions the RF signal, compensating for the reduced strength of signals received from in-glass antennas or from splitters used in multiple-tuner configurations.

Fabricated in silicon germanium, the MT1110 is engineered to deliver an extended temperature range (-40 to +85C), outstanding large signal performance, very low noise figure, excellent linearity, extremely low distortion and 5-volt operation. It enables clearer pictures with better audio quality for an optimized price/performance solution. Originally developed for stringent broadband video applications, the MT1110 has undergone the extensive reliability testing and qualification required for mobile TV applications.

MT0755A Bluetooth Audio/Data OneChip
The MT0755A OneChip is a single-package system-on-chip solution, certified to Bluetooth1.1, for wireless voice and data communications. Based on advanced technology developed for 2.4 GHz cordless phones, mobile phones and wireless headsets, this new product is engineered to provide enhancements for automotive hands-free, cable-free applications.

The MT0755A integrates the Bluetooth radio and baseband into one small package and is engineered to offer system-on-chip capabilities unmatched by other solutions. The baseband features an onboard processor, embedded flash memory, analog-to-digital converters, G711 audio codec, dual UART/SPI ports and a wide variety of general-purpose I/O pins. As a key advantage, the MT0755A's level of integration reduces the total bill of materials (BOM) cost for automotive suppliers in implementing a Bluetooth solution, while ensuring robust end products with better ergonomics and aesthetics.

The embedded flash memory can be loaded with Microtune's Bluetooth-certified software and the automotive hands-free profile for direct audio connection from car microphone to mobile phone via the onboard codec and wireless Bluetooth link. Using built-in UART/SPI connections, Microtune's solution enables the transmission of GPS information and telematics data between the car and a variety of devices.

Pricing and Availability
The MT7402 DVB-T MicroModule and MT1110 Broadband Amplifier are available today and are priced at $15.50 and $2.00, respectively, in quantities of 10,000. The Bluetooth MT0755A will be sampling in Q4 with production planned for Q1, 2003, and it is priced at $7.50 in quantities of 100,000. Pricing is also negotiable based on volume, feature sets and customization requirements.
