Product Information

The Realtek RTL8153 10/100/1000M Ethernet controller combines an IEEE 802.3u compliant Media Access Controller (MAC), USB 3.0 bus controller, and embedded memory. With state-of-the-art DSP technology and mixed-mode signal technology, the RTL8153 offers high-speed transmission over CAT 5 UTP cable or CAT 3 UTP (10Mbps only) cable. Functions such as Crossover Detection and Auto-Correction, polarity correction, adaptive equalization, cross-talk cancellation, echo cancellation, timing recovery, and error correction are implemented to provide robust transmission and reception capabilities. The RTL8153 features embedded One-Time-Programmable (OTP) memory that can replace the external EEPROM (93C46/93C56/93C66/TWSI).

The RTL8153 features USB 3.0 to provide higher bandwidth and improved protocols for data exchange between the host and the device. USB 3.0 also offers more advanced power management features for energy saving.

Advanced Configuration Power management Interface (ACPI)—power management for modern operating systems that are capable of Operating System-directed Power Management (OSPM)—is supported to achieve the most efficient power management possible. In addition to the ACPI feature, remote wake-up (including AMD Magic Packet and Microsoft Wake-Up Frame) is supported in both ACPI and APM (Advanced Power Management) environments.
