Clock Generation Overview

PublishTime：2023-05-26

■IDT clock generation products produce timing signals for use in synchronizing a system’s operation. At its most basic level, a clock generator consists of a resonant circuit and an amplifier. The resulting timing signal (or clock signal) can range from a simple 50 percent duty cycle square wave to more sophisticated arrangements. The resonant circuit is usually a quartz piezo-electric oscillator, although simpler tank circuits and even RC circuits may be used in some cases.
■As the timing output becomes more complex, devices may combine a frequency multiplier, frequency divider, and frequency mixer operations to produce the desired output signal. Frequency multipliers and dividers generate an output signal whose output frequency is a harmonic (multiple) of its input frequency, while the mixer generates sum and difference frequencies. Many devices are also known as phase-locked loop clocks (PLL clocks), which contain PLLs used to compare the phase of the input and adjust the frequency of its oscillator to keep the phases matched. Programmable clock generators allow the multiplier or divider values to be changed, allowing a wide variety of output frequencies to be selected without modifying the hardware.
■As the industry-leader in timing solutions, IDT offers a rich portfolio of clock generation devices that satisfy a variety of performance and programmability requirements. From ultra-low jitter devices that offer less than 300 femtoseconds of RMS phase jitter over a 12 kHz to 20 MHz integration range, to highly flexible programmable devices that provide flexibility and performance in a single package.
