Power supply decoupling for parallel terminated transmission line

摘要

The system has a driver power supply (22) with a filter capacitor (32) to supply power to high speed drivers (24). A termination power supply (26) with a filter capacitor (34) supplies power to termination devices (28). A decoupling capacitor (30) is connected between the power supplies. The capacitance of the decoupling capacitor is equal to or greater than the capacitance of the filter capacitor of termination power supply. An independent claim is also included for a method of communicating data over a transmission line.
