MaxLinear GPY241B0BC

The GPY241 and GPY245 are 4-port 2.5Gb Ethernet PHYs suited for routers, switches, and home gateways. The devices support the 2.5GBASE-T, 1000BASE-T, 100BASETX and 10BASE-Te modes of the IEEE802.3 standard and provide great interoperability for high data rate connections as well as for connections to legacy 1000BASE-T, 100BASE-TX and 10BASE-T devices. The GPY241 and GPY245 connect to a switch or gateway MAC interface by either a single four pin 10G USXGMII- 4x2.5G interface or four SGMII+ interfaces. SGMI+ is a Serial-GMII (SGMII) interface clocked with 3.125Gbaud/s to support a data rate of 2.5Gbit/s. Rate adaptation using IEEE 802.3x pause frames is supported for 10Mbit/s, 100Mbit/s, and 1Gbit/s transmission over the SGMII+ interfaces or the USXGMII interface. Faster Ethernet connectivity enables users to make the most of increased speeds available through the enhanced broadband access networks. 2.5Gigabit Ethernet (GbE) increases the bandwidth without the need to change cables, is more cost-effective, and consumes less power than 5GbE or 10GbE.
