CMOS IC
LC72709E, 72709W
FM Multiplex Reception IC for Mobile Systems
Overview
The LC72709E is a data demodulation IC for receiving
FM multiplex broadcasts for mobile receivers in the
DARC format. This IC includes a built-in bandpass filter
that extracts the DARC signal from the FM baseband
signal. Since this IC supports all of the FM multiplex
broadcast frame structures (methods A, A', B, and C) from
the ITU-R recommendations, it is optimal for use in radios
for worldwide use that support FM multiplex reception.
