Method and apparatus for transmitting signals over long distances on an integrated circuit device

An integrated circuit device, comprising:

• dispatcher circuitry configured to receive signals from a first number count of signal sources, to multiplex the signals into a single mixed signal according to a predetermined order, and to transmit the single mixed signal to a signal destination via a mixed signal interface having an arbitrary length, the mixed signal interface operating at an interface clock frequency equal to a product of a device clock frequency and the first number count;
• a second number count of samplers disposed along the mixed signal interface and connected in series, each of the samplers being configured to sample the mixed signal and to output a sampled mixed signal that is synchronized to the interface clock;
• a chain of tracking elements, corresponding in number to the second number count and connected in series, and configured to output a tracking indication that is separate from the sampled mixed signal;
• and
• capture circuitry coupled to a last sampler among the second number count of samplers and to a last tracking element among the second number count of tracking elements, the capture circuitry being configured to receive the sampled mixed signal and to demultiplex the sampled mixed signal according to a starting point based on the tracking indication received from the last tracking element, and to output, to a plurality of signal buses corresponding in number to the first number count, a plurality of demultiplexed signals corresponding to the signals from the first number count of signal sources that were multiplexed into the mixed signal, according to the starting point.
