Abstract: In accordance with embodiments disclosed herein, there is provided systems and methods for on-chip jitter tolerance testing. A receiver component includes a clock data recovery (CDR) logic circuit. The CDR logic circuit includes a controller to receive a phase signal and to output a DCO control signal; jitter injection (JINJ) logic to generate a first jitter signal at a first frequency and a first amplitude; and digitally controlled oscillator (DCO) to receive the first jitter signal applied to the DCO control signal and to output, based on the first jitter signal applied to the DCO control signal, a first DCO clock signal for on-chip jitter tolerance testing.
