Isochronous timing

A sequence of events is isochronous if the events occur regularly, or at equal time intervals. The term "isochronous" is used in several technical contexts, but usually refers to the primary subject maintaining a constant period or interval (the reciprocal of frequency), despite variations in other measurable factors in the same system. Isochronous timing is a characteristic of a repeating event whereas synchronous timing refers to the relationship between two or more events.
