Overview

The LC72717PW is a data demodulation LSI for receiving FM multiplex broadcasts for mobile reception in the

DARC format. This LSI includes an on-chip bandpass filter for extracting the DARC signal from the FM baseband

signal. It also supports ITU-R recommended FM multiplex frame structures (methods A, A’, B, and C) and can

implement a compact, multifunction DARC reception system.

The LC72717PW’s package, pin assignment and electrical characteristics are same as the LC72715PW (VICS-LSI).

Functionally, the LC72717PW is a product that VICS function is removed from the LC72715PW.

The LC72717PW is also control-compatible with the LC72711LW.

Note that a contract with the NHK Engineering System, Inc. may be required to produce DARC compatible

products in case, please contact with the NHK Engineering System, Inc.

Functions

 Adjustment-free 76kHz 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

 7.2MHz 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: 2.7V to 3.6V
