  We present recent measurements by SLD of the branching fractions of B hadrons
to states with 0 and 2 open charm hadrons, BR_{0D} and BR_{2D}, from which both
the average charm yield per B decay, N_c and the inclusive branching ratio into
rare modes not containing any charmed hadrons, BR_{rare} can be derived. We
also present a new measurement of the B_d mixing frequency Delta m_d and limits
on the B_s mixing frequency Delta m_s. These analyses take advantage of the
excellent vertexing resolution of the VXD3, a pixel-based CCD vertex detector,
which enables the topological separation of the B and cascade D decay vertices.
