  We present detailed broadband timing and spectral analysis of the persistent,
low luminosity and slowly spinning pulsar X Persei using a deep Suzaku
observation of the source. The spectrum is unusually hard with a cyclotron
resonance scattering feature (CRSF), the presence of which has been debated. By
comparing the spectral models relevant for accretion powered pulsars, we have
obtained the best constraint on the broadband spectral model of X Persei
obtained so far. The CRSF is not confirmed in the average spectrum. We have
also identified, the presence of different intensity levels in the source with
distinct changes in the pulse profile and energy spectrum indicating changes in
the accretion geometry. We further find evidence of a CRSF in the highest
intensity levels at $\sim$ 40 keV, indicating a magnetic field strength of
3.4$\times10^{12}$ G.
