The present disclosure provides apparatus and methods for dynamic analog tuning for power reduction. As disclosed herein, the analog controls on a high-speed serial communication channel are dynamically adjusted in a manner so as to either reduce the total system power or move power dissipation between the transmitter and receiver devices, with little or no negative effect to the bit error rate. One embodiment relates to a method for tuning a communication link. The method includes occasionally determining whether the bit error rate for the communication link is acceptably low. Control parameters for analog circuitry of the communication link are adjusted to decrease power used if the bit error rate is acceptably low and are adjusted to increase power used if the bit error rate is not acceptably low. Other embodiments, aspects and features are also disclosed.
