The disclosed apparatus may include (1) a plurality of SerDes devices that each facilitate transmitting and receiving communications in connection with a network device and (2) at least one phase-adjustment device communicatively coupled to a first SerDes device included in the SerDes devices, wherein the phase-adjustment device mitigates crosstalk among the SerDes devices by (A) receiving at least one reference clock signal, (B) generating at least one phase-adjusted clock signal based at least in part on the reference clock signal such that the phase-adjusted clock signal and the reference clock signal are out of phase with respect to one another, and (C) delivering the phase-adjusted clock signal to the first SerDes device to ensure that the SerDes devices are switching out of phase with respect to one another. Various other apparatuses, systems and methods are also disclosed.
