LC72711W Datasheet, PDF (1/29 Pages) Sanyo Semicon Device – Mobile FM Multiplex Broadcast DARC Receiver IC

Ordering number : ENN6167
CMOS IC
LC72711W, 72711LW
Mobile FM Multiplex Broadcast (DARC)
Receiver IC
Overview
The LC72711W and LC72711LW 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. Furthermore, since this IC
supports all of the IT-R recommended FM multiplex
frame structures (methods A, A', B, and C), it is optimal
for worldwide market radios that provide FM multiplex
reception. The LC72711W and LC72711LW support both
parallel and CCB serial CPU interfaces.
Functions
• Adjustment-free 76 kHz SCF bandpass filter
• Supports all FM multiplex frame structures (methods A,
A', B, and C) under CPU control.
• 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
• Applications can use either a parallel CPU interface
(DMA) or a CCB serial interface.
• Supply voltage: 4.5 to 5.5 V (LC72711W), 2.7 to 3.6 V
(LC72711LW)
