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.
Functions
• Adjustment-free 76 kHz SCF bandpass filter
• Built-in VICS decoder
• MSK delay detection system based on a 1T delay.
• Error correction function based on a 2T delay (in the
MSK detection stage)
• Digital PLL based clock regeneration function
• Shift-register 1T and 2T delay circuits
• Block and frame synchronization detection circuits
• Functions for setting the number of allowable BIC errors
and the number of synchronization protection
operations.
• Error correction using (272, 190) codes
• Built-in layer 4 CRC code checking circuit
• On-chip frame memory and memory control circuit for
vertical correction
• 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.
• Supply voltage: 2.7 to 3.6 V
