LC72717PW

Mobile FM Multiplex Broadcast

(DARC) Receiver IC

Overview

www.onsemi.com

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.

SPQFP64 10x10 / SQFP64

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: 2.7 V to 3.6 V

* Computer Control Bus (CCB) is an ON Semiconductor’s original bus format and

the bus addresses are controlled by ON Semiconductor.
