Ordering number : EN6037 CMOS IC LC72723, LC72723M RDS Demodulation IC Overview The LC72723 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 by the IC itself.
