AM/FM Tuner Block

SANYO's digital radio system is a chipset consisting of the LC75030W car audio tuner/IF-DSP

system IC and the LV25300M tuner system IC.

By converting the analog waveform to digital with the DSP, this chipset achieves a significant

reduction in the number of external components and improvements in reception performance

and reliability.
