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.

Functions
• Bandpass filter: Switched capacitor filter (SCF)
• RDS demodulation: Functions include 57kHz carrier
   regeneration, clock regeneration, biphase decoding, and
   differential decoding
• Buffer RAM: Stores 128 bits (about 100 ms) of data.
• Data output: Output can be switched between master
   mode and slave mode readout.
• RDS ID detection: Supports ID reset
• Standby control: Stops the crystal oscillator.
• Fully adjustment free.

Ratings
• Operating supply voltage: 4.5 to 5.5 V
• Operating temperature: –40 to 85°C
• Packages: DIP16 and MFP16
