Gigabit Ethernet transceiver with three supply rails
The LAN8830-V/PSA is a Gigabit Ethernet transceiver from Microchip, supporting 10/100/1000 Mbps data rates with both full and half duplex operation. It integrates four driver and four receiver channels, making it suitable for multi-port media conversion or backplane applications. The part requires three separate supply voltage domains: a core rail at 1.067V to 1.21V, an I/O rail at 2.375V to 2.75V, and a third rail at 3.135V to 3.63V. This triple-rail architecture is typical for modern PHYs that separate core logic, SerDes, and I/O power.
It is ROHS3 compliant.
