The MAX24288 is a flexible, low-cost IEEE 1588 clock and timestamper with an SGMII or 1000BASE-X serial interface and a parallel MII interface that can be configured for GMII, RGMII, or 10/100 MII. The device provides all required hardware support for high-accuracy time and frequency synchronization using the IEEE 1588 Precision Time Protocol. In both the transmit and receive directions 1588 packets are identified and timestamped with high precision. System software makes use of these timestamps to determine the time offset between the system and its timing master. Software can then correct any time error by steering the device's 1588 clock subsystem appropriately. The device provides the necessary I/O to time-synchronize with a 1588 master elsewhere in the same system or to be the master to which slave components can synchronize.

In addition, the MAX24288 is a full-featured, 10/100/1000 Mbps parallel-to-serial MII converter. It provides full SGMII revision 1.8 compliance and also interfaces directly to 1Gbps 1000BASE-X SFP optical modules.
