2.5G Ethernet PHY (4 port), USXGMII-M
GPY241 is a quad-port 2.5Gbit/s Ethernet PHY with PTP (IEEE1588v2) support suited for routers, switches, and home gateways.
The device supports the 2.5GBASE-T, 1000BASE-T, 100BASE-TX and 10BASE-Te modes of the IEEE802.3 standard and provides great interoperability for high data rate connections as well as for connections to legacy 1000BASE-T, 100BASE-TX and 10BASE-T devices.
GPY241 can be connected to a switch or gateway MAC interface by either a single four pin 10G USXGMII-4×2.5G interface or four SGMII+ interfaces.
The SGMII+/SGMII and USXGMII interfaces support 10M, 100M, 1G and 2.5Gbit/s rates or a fixed rate of 2.5Gbit/s with IEEE802.3x rate adaptation using pause frames.
GPY241 has a typical power consumption of 1W per port in 2.5GBASE-T mode. For reduced power consumption during periods of low traffic, Energy Efficient Ethernet (EEE) is supported for 2.5GBASE-T, 1000BASE-T and 100BASE-TX. Additional power saving can be achieved by using the Wake-on-LAN (WoL) functionality.
For Industrial, transportation and mobile networking applications requiring time synchronization, GPY241 supports timestamp insertion and retrieval according to the IEEE 1588v2 standard.
