DESCRIPTION
*$3*36 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. Output for RDS signal quality is also present. Table 1.
