  In this paper we present some preliminary result on the spectral and timing
analysis of the X-ray pulsed emission from the 16 ms pulsar PSR J0537-6910 in
the energy range 0.1--30 keV, based on archival BeppoSAX and RossiXTE
observations. This pulsar, discovered by Marshall et al.(1998) in the LMC field
with RXTE, is the fastest spinning pulsar associated with a supernova remnant.
It is characterized by strong glitch activity with the highest rate of all
known Crab-like system.
