Flexible multi-standard broadcast radio front end IC provides excellent reception
( 01 Apr 2008 )
Atmel Corporation’s highly integrated broadcast radio front end IC ATR4262 enables excellent car-radio reception. 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 to 166MHz, including weather band and HD Radio in the US. The AM path covers the entire broadcasting frequency range from 150kHz up to 30MHz, 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.
