The MAX24188 is a flexible, low-cost IEEE 1588

clock designed to be the central 1588 time base in a

multiport system. In such systems (typically boundary

clocks or transparent clocks) timestampers at the

ports must all have a common time and frequency

reference. The MAX24188 serves as that common

reference. As the system exchanges 1588 packets

with an external 1588 master and calculates its time

offset vs. the master, the MAX24188 can be adjusted

by system software to zero out the time offset and

thereby achieve time and frequency synchronization

with the master. As the MAX24188 is adjusted, its

output frequency and time alignment signals are

correspondingly adjusted. All timestampers (and

other time-aware components) that receive those

signals then follow the adjustment to maintain

synchronization with the MAX24188. In this way all

1588 elements in the system maintain a common

sense of time and frequency.

The MAX24188 can be a standalone central timing

function for 1588 systems. It can also be used in

conjunction

synchronization ICs in multimode systems designed

to be clocked by 1588, 1588 plus frequency (such as

synchronous Ethernet), or frequency only.
