A clock system for providing a high-speed clock signal to a plurality of integrated circuits is disclosed. The clock system includes an analog signal generator for producing a periodic analog signal of a predetermined frequency and fanout circuitry. The fanout circuitry is coupled to the analog signal generator and includes a transmission line and an RF coupler. The system further includes a plurality of receivers. Each receiver has reference signal input circuitry and clock signal input circuitry. Both the reference signal circuitry and the clock signal circuitry are receptive to coupling locally generated common mode noise. The clock signal circuitry is disposed proximate the RF coupler to provide an RF coupling therebetween.
