Application Field

The ICS650G-40LFT is used in a variety of applications. It is ideal for reducing the size and complexity of a system by eliminating the need for multiple clocks. It can be used for time synchronization and network management. It is also ideal for mission-critical timing applications that require precise timing and low jitter as well as for controlling PLL systems in PCI-Express, SATA, Gigabit Ethernet, and serial peripheral interfaces.

Working Principle

The ICS650G-40LFT is a programmable phase-locked loop (PLL) clock generator with a wide range of frequency and phase levels. It enables the user to program frequencies, phases, and jitter levels of the output clocks. It also supports multiple synchronizing sources.

The device has a crystal oscillator with a wide frequency range,which is used to drive the phase detector and loop filter. The phase detector compares the input clock with the output clock and adjusts the phase and frequency of the output signal to match the input signal. The loop filter smoothes out any glitches in the output signal and ensures that the output phase and frequency are steady. The output signal is then sent to an output switch and a phase-locked loop (PLL) frequency synthesizer that tunes the output clock to the desired frequency.

The PLL frequency synthesizer then tunes the output clock to the desired frequency by multiplying or dividing the input clock in frequency steps. The PLL output can be locked to an external reference clock or to an internal feedback source. The device also supports synchronization to an external sync source. The PLL output is sent to the output switch, which routes the clock signal to the required output. The output signal is stabilized by an adjustable output buffer.

Conclusion

The ICS650G-40LFT is a highly efficient and programmable PLL clock generator that is used in a variety of mission-critical timing applications. It eliminates the need for multiple clocks in a system and can be used for time synchronization and network management. Its wide frequency range, phase level, and jitter level capabilities make it an ideal solution for critical timing applications. The device can be programmed to provide precise timing and low jitter for PLL systems in PCI-Express, SATA, Gigabit, Ethernet and serial peripheral interfaces.
