YT6801S

The YT6801/YT6801S is a single gigabit port Ethernet controller. It integrates IEEE802.3 Ethernet media access controller (MAC), single triple - speed physical layer (PHY) port, One Time Programmable (OTP) and PCI Express x1 controller. It is highly compacted to 32 pin QFN 4x4 package. The embedded PHY is fully IEEE 802.3 standard compliant which supports 1000Base - T, 100Base - TX and 10Base - Te. With AFE, DFE, echo canceller, cross - talk canceller, packets transmit and receive at 1000Mbps rate with no error over 100m or longer CAT.5E cable. Besides, good ESD/Surge performance is also achieved due to the robust analog design. Other features, such as Auto - Crossover, polarity correction and EEE/smart - EEE are also supported. The MAC supports full duplex and half duplex modes. Flow control is supported. It also introduces rich protocol offload functions: ARP/NS offload, TCP large send offload, TCP/UDP checksum offload, IPV4/IPV6 checksum offload. Receive - Side scaling (RSS) is supported to balance the loading of CPUs. Customer can remote wake up PC with WOL function which supports frame pattern matching, magic packet, link change and Microsoft WPI. The PCIe 1.1 controller is enhanced to support various power states, including L0, L1, L1SS, L2 and L3. Together with ASPM/ACPI function, the whole system could enter various low power states, such as Sleep, Hibernation and Modern Stand - by, to save more power. And the controller supports Latency Tolerance Reporting (LTR). MSI and MSI - X are also supported. Only 1 external power rail
