The SSM2517 was designed so that the data line can transition coincident with or close to a clock edge. It is not necessary to delay the data line transition until after the
clock edge because the SSM2517 does this internally to ensure good timing margins. The data line should remain constant during the valid sample period illustrated
in Figure 2; it may transition at any other time.
