DESCRIPTION
SO16 TSSOP16 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. Table 1. Device summary Order code Package E-TDA7479D(1) E-TDA7479AD(1) SO16 TSSOP16 1.
