CMOS LSI
LC72700E, LC72700G
Mobile FM Multiplex Broadcast Receiver LSI
Overview
The LC72700E and LC72700G are data decoder LSIs for
receiving DARC
TM
mobile FM multiplex broadcasts. A
multi-function, compact, adjustment-free system can be
implemented in two chips by combining this LSI with the
LV3400M band-pass filter IC, which extracts the
multiplex components from a composite FM signal.
