MUNICH (electronica 2010) - Nov. 8, 2010 - Silicon Laboratories Inc. today introduced a highly integrated car radio tuner IC family, incorporating the entire radio tuner solution from antenna input to audio output in a single CMOS IC and enabling the lowest system cost for the mid-range automotive radio market.

Silicon Labs’ new automotive-grade Si475x AM/FM receiver family provides unrivaled performance for cost-sensitive automotive radio designs in the high-growth ‘BRIC’ (Brazil, Russia, India and China) markets. Target applications include automotive OEM and aftermarket head units and radio tuner RF modules.

Silicon Labs’ Si475x AM/FM radio ICs provide a cost-effective yet feature-rich and high-performance solution for the mid-grade automotive market. Industry-leading integration in a small 5 mm x 5 mm 32-pin QFN package eliminates the need for several costly external components, dropping the car radio tuner bill of materials by up to 50 percent and reducing the external component count by up to 70 percent. This high level of integration is achieved without sacrificing radio performance or functionality.

Si475x tuner ICs support worldwide radio band requirements including AM, FM, FM radio data system (RDS), long wave (LW) and short wave (SW), giving car radio developers the flexibility to support a variety of global market requirements with a single design. The tuners incorporate Silicon Labs? patented RDS decoding technology, offering RDS performance superior to any other FM RDS demodulator/decoder available.

The Si475x tuner ICs incorporate high-performance standard automotive features such as selectivity, sensitivity, linearity, impulse noise blanking, weak signal processing and dynamic bandwidth control for suppression of strong blockers. The superior linearity of the Si475x tuner?s integrated RF front end, combined with a high-performance on-chip radio DSP and microcontroller, delivers outstanding RF dynamic range and immunity to multi-path fading.
