Introduction:

IDT23S08E-4DC8 is a Clock / Timing - Clock Generators, Phase Locked Loops (PLLs), and Frequency Synthesizers device. It is a device developed by Integrated Device Technology (IDT for short), a global leader in the mixed signal semiconductor industry, to provide low-power, low-jitter clock of any output frequency. The device is a low-cost alternative to the more expensive and power-hungry discrete oscillators, PLLs, and frequency synthesizers, providing a simplified and cost-effective approach for a wide variety of clock generation applications.

Application Field:

IDT23S08E-4DC8 is designed to be used in applications such as local area networks (LANs), wireless communication systems, and other applications requiring high-speed, low-jitter clock source. It also provides a robust solution for any clock distribution application, such as digital signal processor (DSP) and microcontroller-based systems.The IDT23S08E-4DC8 device is designed to be used in the clock generation, synchronization, and timing applications, thereby providing the system designer with a highly reliable and economical clock solution. The device can provide a clock resolution of up to 1 MHz and has a wide frequency range of 0.4 – 160 MHz. The on-chip PLL also allows for frequency and phase adjustment which provides the user with a maximum degree of control and flexibility.

Working Principle:

The IDT23S08E-4DC8 clock generator is based on the technology of phase-locked loops, which is a combination of analog and digital feedback circuitry, that allows for the generation of very accurate and stable clock signals. The loop is composed of a reference oscillator, which acts as the base frequency, a PLL which can be used to adjust the frequency, a digital divider, and a phase detector which monitors the output signal and compares it to the reference signal.The reference oscillator acts as the base frequency and is used to provide the clock source to the system. The PLL is then used to adjust the frequency and phase of the output signal, allowing the user to set and control the desired output frequency. The phase detector monitors the output signal, comparing it to the reference frequency and providing corrections to the PLL when needed.The digital divider is then used to divide the reference frequency down to the desired output frequency, providing a low-power, low-jitter clock signal. The reference clock can be divided down to a wide range of frequencies and this is what gives the device its flexibility and range. The user can select from a wide range of output frequencies and also set the phase and frequency margin of the output signal, giving the user full control over the exact output frequency desired.

Conclusion:

The IDT23S08E-4DC8 clock generator is a versatile and cost-effective solution for clock generation and synchronization applications. Its features such as low-power and low-jitter make it an ideal solution for high-speed communication systems, and its ability to program the output frequency and phase makes it highly configurable and reliable. With its wide range of output frequencies and its ability to provide a clock resolution up to 1 MHz, the IDT23S08E-4DC8 device is an excellent choice for any clock synchronization or timing application.
