September 2013 Rev 8 1/12 12 TDA7479 Single chip RDS demodulator + filter Features ■ Very high RDS demodulation quality with improved digital signal processing ■ High performance, 57 kHz bandpass filter (8th order) ■ FIlter adjustment free and without external components ■ Purely digitaL RDS Demodulation without external components ■ ARI (SK indication) and RDS signal quality output ■ 4.332 MHz crystal oscillator (8.664 and 17.328 MHz optional) ■ Low noise CMOS technology ■ Low radiation Description The TDA7479 recovers the additional inaudible RDS information which is transmitted by FM radio broadcasting stations and operates in accordance with the EBU (European Broadcasting Union) specifications. The device is made up of two sections: a cascaded antialiasing + switched capacitors 8th bandpass filter for precise RDS band selection and a demodulating section that performs the extraction od RDS data stream (RDDA) and clock (RDCL), to be further processed by a suitable RDS decoder. Outputs for RDS signal quality and ARI indication are also present. SO16 TSSOP16 Table 1. Device summary Order code Package Packing E-TDA7479D(1) 1.

TDA7479 Output timing 7/12 3 Output timing The RDS (1187.5Hz) output clock on RDCL line is synchronized to the incoming data. According to the internal PLL lock condition data change can result on the falling or on the rising clock edge (see Figure 3). Whichever clock edge is used by the decoder (rising or falling edge) the data will remain valid for 416.7 µs after the clock transition. Figure 3.

Oscillator controls (FSEL, OSEL) TDA7479 8/12 4 Oscillator controls (FSEL, OSEL) Three different crystal frequencies can be used. The adoption of the internal clock divider to the external crystal is achieved via the input pin FSEL. See the following table for reference: A special mode is introduced to reduce EMI. With pin OSEL connected to GND the internal oscillator is switched off and an external sinusoidal frequency could be applied on OSCIN. The peak to peak voltage of this signal can be reduced down to 60mV. In this mode the frequency selection via FSEL is still active. Suggested values of C1 and C2 are shown in the following table: Table 6. Crystal frequencies Crystal FSEL (pin configuration) 4.332MHz 8.664MHz 17.328MHz connected to GND or open connected to Vs external resistor of 100K to Vs Table 7.
