Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow the guidelines in the 'Ethernet PHY Layout Guidelines' application note (SLAA503) for optimal performance.
The DP83846AVHG/NOPB can be configured for specific network speeds using the SPEED_SEL pins or through the MDIO interface using the PHY register settings. Refer to the datasheet for specific pin configurations and register settings.
The power consumption of the DP83846AVHG/NOPB varies depending on the operating mode and speed. Refer to the datasheet for specific power consumption values, but typical values are around 350mW in 1000BASE-T mode and 150mW in 10/100BASE-TX mode.
Texas Instruments recommends using a common-mode choke and capacitors to filter out electromagnetic interference (EMI). Refer to the datasheet and the 'Ethernet PHY EMI Filtering' application note (SLAA504) for specific component values and layout guidelines.
The DP83846AVHG/NOPB supports cable lengths up to 100 meters for 1000BASE-T and 100BASE-TX modes, and up to 200 meters for 10BASE-T mode, assuming Category 5e or higher cabling.
