Abstract
Disclosed are systems, apparatus, and methods for a self-contained timing and jitter measurement. In various embodiments, a device may include a first clock signal generator operative to provide a first clock signal to a transmitter of a transceiver, where the first clock signal operates at a first frequency. The device may further include a second clock signal generator operative to provide a second clock signal to a receiver of the transceiver, where the second clock signal operates at a second frequency, and where the receiver samples an output of the transmitter at a sampling rate determined by the second frequency. In some embodiments, the device may further include a logic circuit operative to receive an output signal from the receiver and further operative to determine an indication of jitter based on the received output signal.
