    TDA7333N
    Description
    The TDA7333N circuit is a RDS/RDBS signal processor, intended for recovering the inaudible RDS/RBDS informations which are transmitted on most FM radio broadcasting stations.

    Key Features
    3rd order high resolution sigma delta converter for MPX sampling
    Digital decimation and filtering stages
    Demodulation of european radio data system (RDS)
    Demodulation of USA radio broadcast data system (RBDS)
    Automatic group and block synchronization with flywheel mechanism
    Error detection and correction
    RAM buffer with a storage capacity of 24 RDS blocks and related status information
    Programmable interrupt source (RDS block A, B, or D, TA, TA EON)
    I2C/SPI bus interface
    Input frequency range 4-21 MHz
    Power down mode
    3.3 V power supply, 0.35 μm CMOS technology

    TDA7478
    Description
    The TDA7478 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 8thbandpass 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.
    网上最靠谱的赚钱方法 Output for RDS signal quality is also present.

    Key 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
    RDS signal quality output
    4.332 MHz crystal oscillator (8.664 MHz optionaL)
    Low noise cmos technologY
    Low radiation
