Working principle

The IDT2309B-1HPGG clock generator utilizes the integrated Spread Spectrum and Clock Multiplication technology to generate low-jitter clock signals. Spread Spectrum technology is a technique used to reduce the electromagnetic radiation that can be generated by the clock signal. It works by spreading the power of the clock signal over a wide frequency range instead of focusing it on one narrow frequency. This also reduces the amount of jitter, which is the variation in the first clock edge for consecutive cycles.

The Clock Multiplication technology is used to generate high-frequency clock signals from a low-frequency reference clock. It increases the frequency of the reference clock signal by a predefined amount in order to create the desired high-frequency clock signal. This technique ensures that all high-frequency clocks are derived from a single, low-frequency reference clock, resulting in higher overall system integration and lower power consumption.

The IDT2309B-1HPGG clock generator is also able to provide very precise and programmable outputs of reference frequencies and output timing features such as programmable clock oscillator frequency, edge-to-center and cyclic delays, input/output skew, and programmable frequency spreading. The device also comes with an onboard oscillator, eliminating the need to use external quartz oscillators while also providing a high degree of flexibility to clock designs.

Conclusion

The IDT2309B-1HPGG clock generator is a highly integrated, low-power clock generatort that is designed for a variety of low-power and space-constrained applications. It provides very low jitter output clock signals, based on the integrated Spread Spectrum and Clock Multiplicationtechnologies, up to output frequencies as low as 6kHz. Moreover, the onboard oscillator eliminates the need for additional external quartz oscillators, making it ideal for low-power designs.
