Overview
The LC72700E and LC72700G are data decoder LSIs for receiving DARCTM 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.
