Amplitude Problems<\/h2>\n

Amplitude problems include
\nringing (oscillation), \u201cdroop\u201d (decreased amplitude at the start of a pulse), and \u201crunt\u201d pulses (those which don\u2019t reach full amplitude).<\/p>\n

Ground Bounce<\/h2>\n

Ground bounce, caused by excessive current draw (and\/or resistance in the power supply and ground return paths), can cause a circuit\u2019s ground reference level to shift when current demands are high.<\/p>\n

Edge Aberrations<\/h2>\n

Edge aberrations can result from board layout problems or from improper termination or even quality problems in the semiconductor devices.
\nAberrations can include preshoot, rounding, overshoot, ringing, and slow rise time.<\/p>\n

Crosstalk<\/h2>\n

Crosstalk can occur when long traces running next to each other couple their signals together through mutual capacitance and inductance.[\/vc_column_text]<\/div><\/div><\/div><\/div><\/div>

Reflections<\/h2>\n

Reflections can be caused by termination and board layout problems, where the outgoing signal bounces back toward its source and interferes with subsequent pulses.<\/p>\n

Jitter<\/h2>\n

Jitter is defined as edge placement variations from cycle to cycle. Some important causes of jitter are noise, crosstalk and timing instability. This can affect timing accuracy and synchronization throughout a digital system.[\/vc_column_text]<\/div><\/div><\/div><\/div><\/div>
