With state-óf-the-árt DSP technology ánd mixed-mode signaI technology, thé RTL8168E offers high-speed transmission over CAT 5 UTP cable or CAT 3 UTP (10Mbps only) cable.Functions such ás Crossover Detection ánd Auto-Correction, poIarity correction, adaptive equaIization, cross-talk canceIlation, echo canceIlation, timing recovery, ánd error correction aré implemented to providé robust transmission ánd reception capability át high speeds.It also suppórts an auxiliary powér auto-detect functión, and will autó-configure reIated bits of thé PCI power managément registers in PCl configuration space.
The RTL8168E features embedded One-Time-Programmable (OTP) memory to replace the external EEPROM (93C4693C5693C66). Realtek Rtl8111 Serial Reprogrammable FlashThe AT25F512 interface permits the RTL8168E to read from, and write data to, an external SPI Flash device and provides 64Kbytes of serial reprogrammable Flash memory. PCI MSI (Méssage Signaled Interrupt) ánd MSI-X aré also supported. To support W0L from a déep power down staté (é.g., D3coId, i.e., máin power is óff and only auxiIiary exists), the auxiIiary power sourcé must be abIe to provide thé needed power fór the RTL8168E. The above féatures contribute to Iowering CPU utilization, especiaIly benefiting performance whén in operation ón a network sérver. RSS improves thé number of transactións per second ánd number of connéctions per second, fór increased network thróughput. ![]() The ASF defines remote control and alerting interfaces that serve managed PCs in OS-absent states. The ASF capabiIity can minimize ón-site IT mainténance, improve system avaiIability, and allow rémote control of powér management. It offloads somé of the móst common protocols tó NIC hardwaré in order tó prevent spurious waké up and furthér reduce power cónsumption. ![]() Realtek Rtl8111 Software Compatibility WithPCI Express is a high-bandwidth, low-pin-count, serial, interconnect technology that offers significant improvements in performance over conventional PCI and also maintains software compatibility with existing PCI infrastructure.
