Sanyo EP93F manual Digital Radio System Chipsets

Digital Radio System Chipsets						For Automotive AV Equipment
				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
	Single-chip radio tuner			and reliability.
