    APPLICATIONS
    SMPTE 259M serial digital receiver for composite and
    component standards including 4:4:4:4 at 540Mb/s with
    EDH processing; Noise immune digital sync and timing
    generation; Cost effective EDH insertion and checking for
    serial routing and distribution applications.
    DESCRIPTION
    The GS9020A is specifically designed to deserialize SMPTE
    259M serial digital signals. The inclusion of Error Detection
    and Handling (EDH) ensures the integrity of the data being
    received from the serial digital interface (SDI).  Internal 75
    termination 
    resistors 
    allow 
    connection with the GS9035A Reclocker or the GS9025A
    Receiver, thus providing a complete high performance,
    digital video input processor with EDH, digital sync signal
    generation, and other system features.
    INTERLINX 
    seamless
    The GS9020A also includes a parallel to serial converter
    and NRZI scrambler to provide re-serialized, EDH
    compliant data output. The EDH core implements EDH
    insertion and extraction according to SMPTE RP-165. This
    core also generates noise immune timing signals such as
    horizontal sync, vertical blanking, field ID and ancillary data
    identification. It also provides many system features such
    as a FIFO reset pulse (which can be programmed to
    coincide with either EAV or SAV), TRS-ID and ANC header
    correction, user controlled output blanking and ITU-R-601
    output clipping. The GS9020A has an I2C (Inter-Integrated
    Circuit, I2C is a registered Trademark of Philips) serial
    interface bus and an 8-bit parallel port for external access
    to all error flags and device configuration bits.
