Abstract
Systems and methods are disclosed for a multiphase clock generation. An example method includes facilitating, by a phase interpolator (PI) circuit comprising a plurality of PIs, transfer of information across one or both of a transmit (TX) lane or a receive (RX) lane, wherein the transfer of information is based on a clock timing. The PI circuit receives, from a clock-and-data recovery (CDR) circuit, a plurality of input clock phases. The CDR circuit comprises a centrally located phase-locked loop (PLL) circuit and a plurality of multiphase generators. In some embodiments, each multiphase generator of the plurality of multiphase generators is adjacent to a respective PI of the plurality of PIs. Based on the plurality of input clock phases, the PI circuit adjusts, the clock timing for the transfer of information.
