  • Page 16: Lvds Serial Data

    This means that all digital information is passed through the repeater system quickly and completely intact. When a Daniels P25 Receiver receives a P25 digital transmission, the receiver creates an LVDS serial data stream that contains the same information as the Common Air Interface (with some overhead data).

  • Page 17: Mixed Mode Operation

    A mixed mode receiver will receive the incoming FM or C4FM transmission and will automatically detect and demodulate the signal to an analog or P25 digital signal. The receiver will then output either an analog or digital COR signal, as well as the appropriate serial data.
