  We present the measurements of the CKM matrix parameters Vub, Vcb and of the
B mixing oscillation frequency with the BaBar experiment at the asymmetric
B-factory PEPII. Data were collected in the years 2000-2002 and the total
available statistics corresponds to 91 fb-1. The Vub, Vcb measurements utilize
both inclusive and exclusive semileptonic decays of the $B$ meson. The
Delta(md) parameter is measured by using the time evolution of the B,
determined from the flight length difference between the two B mesons.
