Abstract
Method and apparatus for optimizing data transfer over a terminated low voltage differential bus includes controlling parameters of a bus driver, a bus bias cancellation circuit, and other bus operating parameters, in response to received test results derived from test patterns sent over the bus at various transfer rates and parameter settings until optimized parameter settings within an acceptable error margin and at a highest available transfer rate are determined between a particular sending unit and a particular receiving unit on the bus.
