MAX24287

The MAX24287 is a flexible, low-cost Ethernet interface conversion IC. The parallel interface can be configured for GMII, RGMII, TBI, RTBI, or 10/100 MII, while the serial interface can be configured for 1.25Gbps SGMII or 1000BASE-X operation. In SGMII mode, the device interfaces directly to Ethernet switch ICs, ASIC MACs, and 1000BASE-T electrical SFP modules. In 1000BASE-X mode, the device interfaces directly to 1Gbps 1000BASE-X SFP optical modules. The MAX24287 performs automatic translation of link speed and duplex auto-negotiation between parallel MII MDIO and the serial interface.

This device is ideal for interfacing single-channel GMII/MII devices such as microprocessors, FPGAs, network processors, Ethernet-over-SONET or -PDH mappers, and TDM-over-packet circuit emulation devices. The device also provides a convenient solution to interface such devices with electrical or optical Ethernet SFP modules.

Applications/Uses
