MAX24288ETK+T

The MAX24288ETK+T from Analog Devices (Maxim Integrated) is a flexible, low-cost IEEE 1588 clock and timestamper designed for high-accuracy time and frequency synchronization. It features an SGMII or 1000BASE-X serial interface and a parallel MII interface configurable for GMII, RGMII, or 10/100 MII.

This device provides complete hardware support for IEEE 1588 protocols, including ordinary, boundary, and transparent clocks. It offers 1ns input timestamp accuracy and output edge placement accuracy, with time resolution between 2-8ns and period resolution between 2-32ns. The MAX24288ETK+T is steerable by software and includes three time/frequency controls: Direct Time Write, Time Adjustment, and High-Resolution Frequency Adjustment.

Applications for the MAX24288ETK+T include 1588-enabled equipment with 1G Ethernet ports, wireless base stations, switches, routers, DSLAMs, PON equipment, pseudowire circuit emulation, test and measurement systems, industrial automation, and medical equipment. It is housed in a 68-TQFN (8x8) package with a surface mount type.

The device supports IEEE 1588 v1 and v2 packets for both transmit and receive directions, with a packet classifier that supports 1588 over Ethernet. It also provides full SGMII revision 1.8 compliance and interfaces directly to 1Gbps 1000BASE-X SFP optical modules.
