GENERAL DESCRIPTION
Today most FM radio stations in Europe and meanwhile also many FM/AM radio broadcasting stations in the USA transmit the inaudible European RDS (Radio Data System) or the USA RBDS (Radio Broadcast Data System) informations respectively. Likewise nowadays receivers, most car radios and also some home and portable radios on the market include at least some of the RDS features.

FEATURES
• Integrated switched capacitor filters
• Demodulation of the European Radio Data System (RDS) or the USA Radio Broadcast Data System (RBDS) signal
• RDS and RBDS block detection
• Error detection and correction
• Fast block synchronization
• Synchronization control (flywheel)
• Mode control for RDS/RBDS processing
• Different RDS/RBDS block information output modes(e.g. A-block output mode)
• Fast I2C-bus interface
• Multi-path detector
• Signal quality detector with sensitivity adjustment
• Pause detector with pause level and time adjustment
• Alternatively oscillator frequency: n × 4.332 MHz (n = 1 to 4)
• UART compatible with 17.328 MHz (n = 4)
• CMOS device
• Single supply voltage
• Extended temperature range (−40 to +85 °C).
