Abstract:
1. A multichip receiver comprising: first receiver circuitry on a first integrated circuit to process first radio-frequency (RF) signals received from a first signal source; second receiver circuitry on a second integrated circuit to process second RF signals received from a second signal source; and clock-signal generating circuitry to provide phase-matched clock signals to the first and second receiver circuitry, wherein the clock-signal generating circuitry is to generate the clock signals from an off- chip crystal, wherein the first and second receiver circuitry generate substantially phase-matched local-oscillator frequencies from the phase-matched clock signals for use in processing the received RE signals, wherein the clock-signal generating circuitry comprises: a clock driver on either the first or the second integrated circuit to receive signals from the crystal; a signal path to provide an output from the clock driver to an off-chip junction; and matched signal paths to provide the clock signals from the junction to the first and second integrated circuits.
