2.1 Operational Mode

Power consumption depends on the operational mode of the PHY. Depending on the data rate selected, the PHY has different signaling which affects the data coding, voltage and operating frequency. This in turn affects the power demand by the PHY.

See Appendix Section 6.1, Section 6.2 and Section 6.3 for observing the power variation due to change in operational mode.
