LC72723M - Circuito Integrado CMOS, MFP16
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
