Digital Radio System Chipsets |
|
|
|
|
| For Automotive AV Equipment | ||||
| SANYO's digital radio system is a chipset consisting of the LC75030W car audio | |||||||||
|
|
|
|
| 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. | ||||||||
