As clock speeds in communications systems push into the GHz range, phase noise and jitter – always key issues in analog designs – are becoming increasingly critical to the performance of digital chips and boards. Timing errors in the clock or oscillator waveforms of high-speed systems can limit the maximum speed of a digital I/O interface, increase the bit error rate of a communications link, or even cap the dynamic range of an A/D converter.
