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.
