  The recent analysis of the electroweak data at CDF indicates that the
constraint on the top quark mass is $m_t=174\pm 17 $GeV. We accommodate this
result in a new scheme of quark mass matrices in which two elements along the
the leading diagonal are non-vanishing and the other non-vanishing elements are
those due to nearest neighbour interactions. By comparing the quark mixing
matrix elements of our scheme with the experimentally determined Kobayashi-
Maskawa matrix elememts in the standard electroweak model, we find that the CP
violating phases ($\delta_1$ and $\delta_2$) in our model violate the CP
symmetry maximally.
