Fluctuation of the clock edge from its ideal position is termed as clock jitter. For example, a clock period of 1ns having 50% duty cycle should have first rising edge at 0ps, first falling edge at 500ps and second rising edge at 1ns. Deviation of rising/falling edge from its ideal time period is called jitter. cell broadcast deutschland iphone
