General description

The RDS/RBDS demodulator is a CMOS device with integrated filtering and demodulating of RDS/RBDS signals coming from a multiplexed input data stream. Data signal RDDA and clock signal RDCL are provided as outputs for further processing by a suitable microcomputer, for example CCR921 and CCR922.

The SAA6581T replaces SAA6579 in function and pin-compatibility.

Features

  • Integrated switched capacitor filter
  • Demodulates European Radio Data System (RDS) or the USA Radio Broadcast Data System (RBDS) signals
  • Oscillator frequencies: 4.332 or 8.664 MHz
  • Integrated ARI clamping
  • CMOS device
  • Single supply voltage: 5 V
  • Extended temperature range: -40 to +85 Cel
  • Low number of external components.

Applications

The RDS/RBDS system offers a large range of applications from the many functions that can be implemented. For car radios the most important are:

  • Program Service (PS) name
  • Traffic Program (TP) identification
  • Traffic Announcement (TA) signal
  • Alternative Frequency (AF) list
  • Program Identification (PI)
  • Enhanced Other Networks (EON) information.
