About Clock ICs and Clock Timing Integrated Circuit Solutions

A "clock IC" is a broad term used to describe integrated circuits that generate, condition, manipulate, distribute, or control a timing signal in an electronic system. At its most basic level, a clock timing signal oscillates between an electrical high and a low state and is utilized like a metronome to coordinate the actions of circuits. When applied to today's most advanced technologies, clocking ICs must be able to generate accurate clock pulses, and continuously and reliably distribute that signal for use by various timing devices within the system. When operating at such high speeds, system design and environmental factors make it especially challenging to maintain signal quality, often resulting in higher bit error rates (BER) and degraded system performance. Fortunately, Renesas offers a wide range of integrated circuit solutions to meet the stringent system requirements of virtually any application.
