Power dissipation is impacted by temperature, supply voltage, and external source/sink require- ments. All typical measurements were taken at +25°C unless otherwise noted. Power consumption data is split into the following tables: • Typical Four Port (1.21V, 3.3V, 3.3V) Power Consumption • Typical Four Port (1.21V, 2.5V, 2.5V) Power Consumption • Typical Four Port (1.21V, 2.5V, 1.8V) Power Consumption Note 6-3 1.15V/1.27V Total includes: VDDCORE, VDDAL_COMMON, VDDAL_TXL_SERDES, VDDAL_CK125 Note 6-4 2.5V/2.625 VDDAH Total includes: VDDAH_SERDES, VDDAH_PLL_PTP, VDDAH_COMMON, VDDAH_Px. Note 6-5 VDDIO Total includes: VDDIO, VDDIO_1 TABLE 6-1: TYPICAL FOUR PORT (1.21V, 3.3V, 3.3V) POWER CONSUMPTION Device Conditions 1.21V Total (mA) (Note 6-3) 3.3V VDDAH Total (mA) (Note 6-4) 3.3V VDDIO Total (mA) (Note 6-5) Total Device Power (mW) 1588 and SyncE Disabled 4 ports + QSGMII, 1000BASE-T Master link-up, no traffic 758 362 8.6 2138 4 ports + QSGMII, 1000BASE-T Slave link-up, no traffic 756 362 8.6 2137 4 ports + QSGMII, 100BASE-TX link-up, no traffic 257 179 12 940 4 ports + QSGMII, 10BASE-T link-up, no traffic 112 125 19.4 610 4 ports + QSGMII, 10BASE-Te link-up, no traffic 111 125 19.4 610 4 ports + QSGMII, 1000BASE-T Master full-duplex, 100% utilization 781 361 9.3 2165 4 ports + QSGMII, 1000BASE-T Slave full-duplex, 100% utilization 783 361 9.3 2167 4 ports + QSGMII, 100BASE-TX full-duplex, 100% utilization 257 179 11.9 940 4 ports + QSGMII, 10BASE-T full-duplex, 100% utilization 112 185 19.3 807 4 ports + QSGMII, 10BASE-Te full-duplex, 100% utilization 111 200 19.3 857 4 ports + QSGMII, 1000BASE-T Master, EEE Sleep state 222 240 8.4 1086 4 ports + QSGMII, 1000BASE-T Slave, EEE Sleep state 222 240 8.4 1087 |
