FM Multiplex Broadcasting System Chipset s
For Automotive AV Equipment
FM multiplex broadcasting is a new data transmission system that allows reception by mobile receivers and features a large transmission capacity and a wide service area.
SANYO has proposed ICs that exactly match the requirements of each functional block and is now aiming at further product line expansion in this area.
