This product is designed to provide the utmost accuracy in both its Free Run and Reference Clock modes. This article will discuss the application field and working principle of ICS951413CFLFT.

Applications of ICS951413CFLFT

ICS951413CFLFT is designed for application areas that require an ultra-high-speed reference clock frequency, such as networking, broadcast, communications, or data processing. It is ideal for use as a reference clock in wireless infrastructure applications, as it is capable of providing reference clock outputs up to 1GHz. This device is suitable for use in SONET and CPRI systems, as wellas Synchronous Networks, and it is compliant with the Automotive Electronics Council (AEC) Q100 specification. Additionally, the device is compliant with most of the IEEE 1588 requirements for the synchronization of IEEE 802.3 networks.

In addition to its ultra-high-speed applications, the ICS951413CFLFT is also well-suited for mid-range clock frequencies, such as 50 and 54 MHz. This makes it suitable for use as a reference clock in a variety of consumer and industrial applications. Its wide-ranging operating temperature range, between -40°C and +85°C, further offers comfortable margins for a variety of application environments.

Working Principle

The ICS951413CFLFT is a programmable frequency synthesizer and clock multiplier IC. It is designed to allow the user to program both the reference frequency and the output frequency. The device has two input clocks: a free-running oscillator and a reference clock. The free-running oscillator is used by the IC as a source of clock signals, while the reference clock is used to control the frequency and phase of the output clock signals. This allows the user to have a wide range of programmable output clock frequencies.

The ICS951413CFLFT uses a fractional-N frequency synthesizer to produce the output signals. The device makes use of the dual-modulus prescaler architecture to provide a wide range of output frequencies with low phase jitter. In addition, the device offers several features to reduce the reference clock jitter and to adjust the phase of the output clock signals. Furthermore, the device has a built-in spread spectrum feature, which helps minimize EMI problems.

Conclusion

The ICS951413CFLFT is an advanced Clock/Timing solution from IDT designed for a wide range of ultra-high-speed reference clock frequencies, such as 50 and 54 MHz, and is compliant with most of the IEEE 1588 requirements. The device utilizes a fractional-N frequency synthesizer and dual-modulus prescaler architecture to provide a wide range of output frequencies with low phase jitter. Additionally, the device has a built-in spread spectrum feature to aid in meeting EMI requirements in various application environments.
