Abstract
Aspects of the invention include a phase rotator, that is located at a built-in self-test (BIST) path of a receiver, receiving a clock signal from an on-chip clock. The phase rotator shifts the phases of the clock signal. The phase rotator transmits the shifted clock signal to a binary sequence generator, that is located at the receiver. The binary sequence generator outputs a binary sequence, where the binary sequence generator is driven by the shifted clock signal.
