IDT23S08-1DCI is a highly integrated Clock Synthesizer with 1 differential clock output. It is used for applications like signal integrity, high-speed memory systems, embedded processors and digital signal processor systems as well as networking, communications, digital video/consumer, and automotive infotainment. To provide signal integrity and robust timing performances, the device combines a fully-integrated PLL, low-jitter clock distribution, and very low-dropout regulators.

Overview

The IDT23S08-1DCI is a highly integrated clock synthesizer that provides differential clock outputs under PLL synchronisation. It is a single-chip device that provides both low-frequency and high-frequency clock outputs. It delivers good signal integrity with high jitter attenuation, low-dropout regulation, and power-saving mode, as well as supporting up to four high-speed differential clocks. The device also supports multiple clock source to reduce external components and save EMI power.

Features

The IDT23S08-1DCI has the following features which make it suitable for a wide range of applications:

• 1 differential clock output up to 500MHz.
• Low jitter performance from 2kHz to 10MHz.
• High output amplitude to minimize thermal noise.
• Multiple clock source support with EMI reduction.
• Low power dissipation with power-saving mode.
• Able to support standard LVDS outputs.

Working Principle

The IDT23S08-1DCI consists of a clock synthesizer and clocking logic that allow the user to select up to four different sources including crystal oscillators, reference clocks, or LVDS input signals. The clock synthesizer then generates high frequency differential outputs with low jitter performance. The clock outputs are then low-pass-filtered and divided down to get the desired high-speed differential clocks outputs.

Furthermore, the device features adjustable clock frequencies and duty cycles to optimize performance. In addition, the device offers different power-saving modes to reduce power dissipation when the system is idle.

Applications

The IDT23S08-1DCI is designed for a variety of applications, such as high-speed memory systems, embedded processors, digital signal processor systems, networking, communication, digital video/consumer, and automotive infotainment fields. Its low power dissipation, low jitter performance, and high output amplitude make it suitable for these applications.

Conclusion

IDT23S08-1DCI is a highly integrated clock synthesizer designed to provide differential clock outputs under PLL synchronization. It is suitable for many applications, such as high-speed memory systems, embedded processors, digital signal processor systems, networking, communications, digital video/consumer, and automotive infotainment fields. It offers multiple features such as adjustable clock frequencies, adjustable duty cycles, and power-saving mode that make it highly suitable for these applications.
