Description
General part information
LAN8840 Series
The LAN8840 is a low-power, single-port triple-speed (10BASE-T/100BASE-TX/1000BASE-T) Ethernet physical layer transceiver (PHY) that is optimized for precision process timing. The device enables highly accurate synchronization of motors, valves, actuators and sensors over standard CAT-5, CAT-5e and CAT-6, unshielded twisted pair (UTP) cables.
The LAN8840 supports industry-standard RGMII (Reduced Gigabit Media Independent Interface) providing chip-to-chip connection to a host device with an integrated Gigabit Ethernet MAC.
The LAN8840 provides high-accuracy IEEE 1588-2008 (v2) timestamping to support Microchip Time-Sensitive Network (TSN) Ethernet switches, as well as, SoCs and FPGAs supporting the RGMII interface. The LAN8840 also provides Synchronous Ethernet (SyncE), TSN frame preemption support and multiple power saving features.
