World Tuner IC promotes radio reception in mobile systems.January 16, 2008 -
Integrated broadcast radio front end IC, ATR4262, incorporates AGC system that enables matching to all reception conditions. FM section handles frequencies from 70-166 MHz, including weather band and HD Radio in US, while AM path covers entire broadcasting frequencies from 150 kHz to 30 MHz, including modern DRM systems. No external crystals are needed as flexible clock generation enables use of any external clock signal. IF amp has 3 inputs that can be tailored to different filters.

Atmel's Highly Flexible Multi-standard Broadcast Radio Front End IC Provides Excellent Reception Performance
HEILBRONN, Germany, Jan. 7 -- Atmel(R) Corporation (NASDAQ:ATML) announced today the availability of the highly integrated broadcast radio front end IC ATR4262, which enables outstanding car-radio reception. The new IC is designed for high performance applications, in particular for mobile systems such as car radios. The ATR4262 is compatible with the major radio standards including HD Radio, DRM, and AM/FM.
The ATR4262 is a world tuner device covering all AM/FM frequencies worldwide. Its FM section handles the frequency range from 70 MHz to 166 MHz, including weather band and HD Radio in the US. The AM path covers the entire broadcasting frequency range from 150 kHz up to 30 MHz, including modern DRM systems.
While providing maximum flexibility and high performance, the ATR4262's optimized BOM reduces costs. The weather band functionality, for example, can be realized without additional components. Furthermore, no external crystals are needed as the ATR4262 features flexible clock generation enabling the use of any external clock signal.
The ATR4262's flexible AGC system enables matching to all reception conditions. The IF amplifier has 3 different inputs, which can be tailored to different filters. This allows the support of multiple radio standards such as AM/FM; HD Radio, or DRM. In addition, the ATR4262 provides several control possibilities, thus allowing connection to various baseband processors.
Availability and Pricing
Samples of the ATR4262 are now available in very small QFN packages for small and miniature tuner solutions. Pricing starts at US $2.00 for 100k piece quantities. Sample design demo boards are also available.
