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

Detailed Description

The Microchip LAN8042 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 LAN8042 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 LAN8042 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.

The LAN8042 includes strong Ethernet security based on IEEE 802.1AE MACsec, including advanced per-flow encryption and VLAN tag in the clear capabilities and both 128-bit and 256-bit AES encryption.
