MAX24287

1Gbps Parallel-to-Serial MII Converter

General Description

Highlighted Features

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 support

SGMII master and 1000BASE-X autonegotiation

without software involvement.

Bidirectional Wire-Speed Ethernet Interface

Conversion

Can Interface Directly to SFP Modules and

SGMII PHY and Switch ICs

Serial Interface Configurable as 1000BASE-X or

SGMII Revision 1.8 (4-, 6-, or 8-Pin)

Parallel Interface Configurable as GMII, RGMII,

TBI, RTBI, or 10/100 MII

Serial Interface Has Clock and Data Recovery

Block (CDR) and Does Not Require a Clock

Input

♦

Translates Link Speed and Duplex Mode

Negotiation Between MDIO and SGMII PCS

Supports 10/100 MII or RGMII Operation with

SGMII Running at the Same Rate

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.

Configurable for 10/100 MII DTE or DCE

Modes (i.e., Connects to PHY or MAC)

Can Also Be Configured as General-Purpose

1:10 SerDes with Optional Comma Alignment

Supports Synchronous Ethernet by Providing

a 25MHz or 125MHz Recovered Clock and

Accepting a Transmit Clock

Applications

♦

Can Provide a 125MHz Clock for the MAC to

Use as GTXCLK

Any System with a Need to Interface a Component

with a Parallel MII Interface (GMII, RGMII, TBI RTBI,

10/100 MII) to a Component with an SGMII or

1000BASE-X Interface

Accepts 10MHz, 12.8MHz, 25MHz or 125MHz

Reference Clock

Can Be Pin-Configured at Reset for Many

Common Usage Scenarios
