  We report the results from a detailed spectro-imaging and temporal analysis
of an archival XMM-Newton observation of a new intermediate polar XMMU
J185330.7-012815. Its X-ray spectrum can be well-described by a
multi-temperature thermal plasma model with the K-lines of heavy elements
clearly detected. Possible counterparts of XMMU J185330.7-012815 have been
identified in optical and UV bands. The low value of the inferred X-ray-to-UV
and X-ray-to-optical flux ratios help to safely rule out the possibility as an
isolated neutron star. We confirm the X-ray periodicity of ~238 s, but
different from the previous preliminary result, we do not find any convincing
evidence of phase-shift in this observation. We further investigate its
properties through an energy-resolved temporal analysis and find the pulsed
fraction monotonically increases with energy.
