Quad-Port 25G Optical Ethernet PHY Transceiver in 256-ball HFC-BGA package

Detailed Description

The Microchip LAN8044 is a quad-port 1G/10G/25G serial optical Ethernet PHY transceiver which provides multiple line and host interface options.

On the line interfaces, the LAN8044 supports transmission and reception of data over a variety of optical module serial interfaces. These serial interfaces support both optical modules and copper cables. On the host interfaces, the LAN8044 supports transmission and reception of data over a variety of chip-to-chip and backplane serial interfaces. An integrated Cross-Connect function enables any line port to connect to any host port. Host Redundancy options are provided.

LAN8044 includes high-accuracy timestamping functions to support IEEE-1588 solutions using Microchip Ethernet switches, as well as customer solutions based on SoCs and FPGAs. Synchronous Ethernet (SyncE) and TSN Frame Preemption is supported. Strong Ethernet security based on IEEE 802.1AE MACsec is supported, including advanced per-flow encryption and VLAN tag in the clear capabilities and both 128-bit and 256-bit AES encryption.
