Ordering number : EN6037 CMOS IC LC72723, LC72723M RDS Demodulation IC Overview Package Dimensions The LC72723 is an RDS (Radio Data System) signal unit: mm demodulation IC. This IC integrates a bandpass filter, the 3006B-DIP16 demodulation circuit, and buffer RAM on a single chip LC72723 and can read out RDS data in slave mode operation with 16 9 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. 1 8 19.2 Functions Bandpass filter: Switched capacitor filter (SCF) RDS demodulation: Functions include 57kHz carrier regeneration, clock regeneration, biphase decoding, and differential decoding 1.2 0.71 2.54 0.48 SANYO: DIP16 Buffer RAM: Stores 128 bits (about 100 ms) of data. Data output: Output can be switched between master unit: mm mode and slave mode readout. RDS ID detection: Supports ID reset 3035A-MFP16 Standby control: Stops the crystal oscillator.
