CMOS IC
LC72710W, 72710LW
Mobile FM Multiplex Broadcast (DARC) Receiver IC
with On-Chip VICS Decoder
Overview
The LC72710W and LC72710LW are 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 LC72710W and LC72710LW
support both parallel and CCB serial CPU interfaces, and
integrate the circuits required for simultaneous reception
of both VICS data and dGPS service data. 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: 4.5 to 5.5 V (LC72710W), 2.7 to 3.6 V
(LC72710LW)
