LC72714W
LC72714W is Mobile FM Multiplex Broadcast manufactured by SANYO.
Ordering number : ENN6871A
CMOS IC
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 pact, 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 d GPS 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 d GPS and VICS data
- Applications can use either a parallel CPU interface (DMA) or a CCB serial interface.
- Supply voltage: 2.7 to 3.6 V
Package Dimensions unit: mm 3190-SQFP64
