Ordering number : ENN7672A SANYO Semiconductors DATA SHEET LC72725M LC72725V LC72725NV CMOS IC RDS Demodulation IC Overview The LC72725 is an RDS (Radio Data System) signal demodulation IC.

This IC integrates a bandpass filter, the demodulation circuit, and buffer RAM on a single chip and can read out RDS data in slave mode operation with the provision of an external clock input.

It also supports master mode, in which the data is read out in synchronization with an RDS clock output provided

LC72725V Features

* mode was data item n, then data starting with item n+1 will be written to memory.

* Timing of the switch from slave mode to master mode After all data has been read from memory and READY has gone low, the application must then wait until
