System and Method for Generating LO Frequencies with Phase Locking in 2 Steps

Abstract

System and method for generating multiple local oscillator signals comprising a first-stage phase-locked loop (PLL) having an input to receive a first reference signal input and having an output to transmit a second reference signal, wherein the second reference signal is an integer or fractional multiple of the first reference signal; and a plurality of second-stage PLLs, each second-stage PLL having an input coupled to the output of the first-stage PLL and receiving the second reference signal, and each second-stage PLL having an output for transmitting a local oscillator signal, wherein each of the local oscillator signals is an integer multiple of the second reference signal.
