SMBus digital switching characteristics

The switching characteristics of the SA56004X fully meet or exceed all parameters specified in SMBus version 2.0. The following parameters

specify the timing between the SCLK and SDATA signals in the SA56004X. They adhere to, but are not necessarily specified as the SMBus

specifications.
