Adaptive power-supply regulation is extended to serial links, by using 5:1 multiplexing and low-voltage transceivers for power saving, and by scaling link properties with bit rate, especially in per-pin clock recovery PLL/DLLs. The serial link operates at 0.45-3.5 Gb/s for 0.9-2.5 V supply and dissipates 9.2-197 mW.
