Jitter Effects and Measurement in Serial Digital Television Signals

Just as the definition and measurement of jitter in baseband NTSC signals was a difficult topic for many years, we are now finding that jitter is of significant interest and some controversy in the implementation of serial digital audio and video systems. Specifications such as 40 ns of jitter in AES/EBU digital audio and 0.5 ns of jitter in serial digital video are important to insure conformance to the proposed standard. It is necessary to define jitter and appropriate measurement methods as well as understand how acceptable jitter in the signal interconnection system may affect resulting analog signals. Test methods can use wideband oscilloscopes or recently available television waveform monitors. Measurement of jitter in serial data systems is a developing subject for television applications. Several methods of measuring jitter and test results for both digital audio and digital video are discussed.
