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.
