DCI provides a tuned on-die input single termination to V_CCO on the receivers and a tuned on-die source termination option (OUTPUT_IMPEDANCE) of 40 Ω, 48 Ω, or 60 Ω of driver impedance in HP I/O banks. The impedance is scaled from the reference resistor on the VRP pin. The driver output impedance is set to a default of 48 Ω.The differential (DIFF_) versions use complementary single-ended drivers for outputs, and differential receivers for inputs.
