IBiquity Digital has approved a reference design and tuner from Sanyo Semiconductor Corp. for HD Radio applications. Sanyo Semiconductor joins NXP in offering radio receiver manufacturers a front-end chipset that can be integrated with HD Radio decoders at a low cost.
Though the Sanyo SDRS-400 reference design and its LC75040 tuner are intended mainly for automotive products, the companies say the solution works in other applications as well. The reference design has two ICs; together, they provide a digitized interface that can be combined with HD Radio decoder ICs. The design integrates a digital AM/FM tuner, RDS, audio function and a micro computer into a single DSP chipset for a car radio.
More than 1.5 million HD Radio chip sets have been manufactured and more than 1 million modules shipped, with more than 100 different HD Radio products available to consumers today, according to iBiquity.
