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 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.
• Low voltage: 2.7 to 5.5 V (LC72723: 4.5 to 5.5 V)
• Improvement sample in crystal oscillation capability: LC72725NV
• Fully adjustment free.
Ratings
• Operating supply voltage: 2.7 to 5.5 V
• Operating temperature: –20 to +70°C
• Packages: MFP16 and SSOP16 (LC72723: DIP 16 and MFP16)
