Hot-selling and scarce MAX24287ETK+ 1Gbps Parallel-to-Serial MII Converter 68TQFN spot stock

Product Descriptions

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 autonegotiation between parallel MII MDIO and the serial interface. Microprocessor   interaction   is  optional  for  device operation.    Hardware-configured    modes    supportSGMII   master   and   1000BASE-X   autonegotiation without software involvement.

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.
