Microchip — LAN8814 Ethernet Transceiver

Microchip has introduced the LAN8814, a low-power quad-port Gigabit Ethernet physical layer (PHY) transceiver which supports the requirements of the latest time-sensitive networking (TSN) standards, including Ethernet frame pre-emption and synchronous Ethernet (SyncE).

The LAN8814 provides a new option for manufacturers of industrial equipment, which are increasingly turning to TSN as a single carrier for streams of data traffic running in multiple protocol layers.

An integrated TSN transceiver chipset, the LAN8814 reduces costs and time-to-market for manufacturers of connected systems which rely on precise network timing, and the synchronization and connectivity of industrial devices such as cameras, barcode readers, scanners and conveyors.

The LAN8814 provides chip-to-chip connections to four Gigabit Ethernet media access controllers (MACs). The device supports the industry-standard quad serial Gigabit media independent interface (QSGMII) and quad universal serial Gigabit media independent interface (Q-USGMII).

The LAN8814 supports data transmission speeds of 10 Mbits/s, 100 Mbits/s or 1 Gbit/s

on standard Cat 5, as well as Cat 5e and Cat 6 unshielded twisted-pair cables.

The LAN8814 Ethernet PHY complements the LAN9668x family of Ethernet switches from Microchip.  Designers using LAN9668 and LAN8814 products can use the TSN chipset to implement timing, stream reservation, protection and management. The devices can be used with the IStaX/SMBStaX and WebStaX network operating systems from Microchip, providing a complete hardware and software system to support rapid time-to-market for industrial or commercial equipment.
