The receiver circuit includes a 12 dB cable equalizer to compensate nonconstant cable attenuations and a PFLL for data regeneration. The transmitter includes a cable driver which supplies a stable IVpp signal amplitude to the transmission line and a PLL to extract a 310 MHz clock signalThe purpose of the receiver/interface circuit is to passRF to the receiver through capacitor 09,while adding dc power to the feedline through R2 and RF  choke L7.A data receiver interface circuit is provided with a circuit for accepting correctly framed data. The plurality of data bits sandwiched between a pair of frame pulses is temporarily stored while the number of clock cycles occurring between the frame pulses is determined to be a valid number.
