LC72714W

Ordering number : ENN6871A CMOS IC LC72714W Mobile FM Multiplex Broadcast IC with On-Chip VICS Decoder Overview The LC72714W is data demodulator ICs for receiving FM multiplex broadcasts for mobile reception in the DARC format. This IC includes an on-chip bandpass filter for extracting the DARC signal from the FM baseband signal. It also integrates a decoder circuit that performs the VICS data processing on the same chip and can implement a compact, multifunction VICS reception system. The LC72714W is an improved version of the LC72710W that features circuit improvements that allow a single tuner to receive both the VICS data and the dGPS data supported by the earlier device. Note that a contract with VICS Center is required to evaluate this sample IC and to produce end products that support VICS. 7.2 MHz crystal oscillator circuit Two power saving modes: STNBY and EC STOP Dedicated frame synchronization circuit for simultaneous reception of dGPS and VICS data Applications can use either a parallel CPU interface (DMA) or a CCB serial interface.
