RDS Demodulation
Description
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.

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.
