Abstract
Signal format conversion apparatus and methods involve converting data signals between a first signal format associated with a first reference clock rate and a second signal format that is different from the first signal format and is associated with a second reference clock rate different from the first reference clock rate. A period of the second signal format is changed to match a period of a third signal format by controlling a synchronized second reference clock rate that is applied in converting data signals between the first signal format and the second signal format. The synchronized second reference clock rate is different from the second reference clock rate and is synchronized with a third reference clock rate. The third reference clock rate is associated with the third signal format. Such synchronization simplifies conversion of signals between the second and third signal formats.
