MAX24287ETK2T

Specialized Overview

The MAX24287ETK2T is a flexible, low-cost Ethernet interface conversion IC manufactured by Microchip Technology. It functions as a 1Gbps parallel-to-serial MII converter, translating between parallel interfaces (GMII, RGMII, TBI, RTBI, or 10/100 MII) and serial interfaces (1.25Gbps SGMII or 1000BASE-X). The device performs automatic translation of link speed and duplex autonegotiation between the parallel MII MDIO and the serial interface. It operates within a supply voltage range of 1.14V to 3.465V and is housed in a 68-TQFN-EP(8x8) package with exposed pad for surface mount installation.

Specialized Feature Summary

• Bidirectional wire-speed Ethernet interface conversion capability
• Serial interface configurable for 1000BASE-X or SGMII operation
• Parallel interface supports GMII, RGMII, TBI, RTBI, or 10/100 MII configurations
• Integrated clock and data recovery block eliminating external clock input requirements

Specialized Applications

• Interfacing single-channel GMII/MII devices such as microprocessors and FPGAs
• Connection to Ethernet switch ICs, ASIC MACs, and 1000BASE-T electrical SFP modules
• Integration with 1Gbps 1000BASE-X SFP optical modules
• Ethernet-over-SONET or -PDH mappers and TDM-over-packet circuit emulation devices

Specialized Procurement Notes

Verify the specific suffix ETK2T against the official datasheet to confirm package type and tape-and-reel quantity specifications. Ensure compatibility with the required operating temperature range and supply voltage levels for the target application environment before finalizing procurement decisions.

Specialized Selection Notes

Select this component when direct interfacing between parallel MII-based processors or network processors and serial SFP modules is required without software involvement for mode configuration. Consider hardware-configured modes for SGMII master and 1000BASE-X autonegotiation if minimal microprocessor interaction is desired for system design simplicity.

Specialized Part Context

This device belongs to the MAX24287 family of serializers and deserializers designed for Ethernet interface conversions. It serves as a bridge between legacy parallel media independent interfaces and modern serial optical or electrical transceiver standards, facilitating integration in network infrastructure equipment requiring high-speed data translation.

Specialized Replacement Considerations

Consult official Microchip documentation for confirmed substitute part numbers. Verify pinout compatibility and electrical parameter alignment if considering alternative components from other manufacturers for redesign purposes.
