Presented herein are methodologies for generating clock signals for transceivers that rely on frequency and phase error correction functions. The methodology includes generating a differential clock signal at a fundamental frequency, generating, based on the differential clock signal and using a multiphase generator, four quadrature signals at the fundamental frequency, supplying the four quadrature signals to an injection-locked phase rotator, and outputting, from the injection-locked phase rotator, a phase adjusted multiphase clock signal based on the four quadrature signals.
