Deep Power Down shuts down all PHY circuitry except the SMI. In this mode, the PHY PLL is shut-down to further reduce power consumption.
Deep Power Down is activated by first enabling IEEE Power Down (from either the SMI or INT/PWDN_N pin) and then setting bit[2] = 1 in the Deep Power Down Control Register (DPDWN, address 0x0428).
