Patent ID: 7356077

Claim:
A method for testing network integrity of test equipment by generating jittered data, comprising: determining a desired phase jitter to be used for a data stream used to test test equipment; generating a sine of phase angle and a cosine of phase angle with respect to the desired phase jitter; inputting the sine of phase angle and the cosine of phase angle with respect to the desired phase jitter to a quadrature mixer, for which a reference clock waveform is also inputted thereto, and obtaining a phase modulated clock signal as a result thereof; inputting the phase modulated clock signal to a clock input of a flip-flop; dividing the phase modulated clock and providing the divided phase modulated clock to a select port of a multiplexer which receives an NRZ data stream on its input port; providing the multiplexed NRZ data stream obtained at an output port of the multiplexer to a data input of the flip-flop; and testing integrity of the test equipment by providing a jittered NRZ data stream to the test equipment as obtained from an output port of the flip-flop.
