ICS650G-40LF is a low jitter clock generator and frequency synthesizer from IDT whose applications cover a broad range of industries and needs. Offered as a cost-effective solution for crystalline generating, ICS650G-40LF can be found in a variety of applications including data communication, industrial automation, and consumer products.

ICS650G-40LF is a PLL-based clock generator/frequency synthesizer with a combination of clock output frequencies. It works by using an on-chip spread spectrum oscillator to continuously modulate the output frequency, providing better, more cost-effective clock frequency stability for most applications.

The ICS650G-40LF offers low jitter, fast lock times, and stability over a range of extended operating temperatures, making it an ideal choice for applications where accuracy and reliability are paramount. It also offers a choice between external and internal reference clock sources, which can enable designers to more easily meet their clock requirements.

ICS650G-40LF is designed with a PLL system and supports four clock output frequencies. It uses a programmable Feedback Frequency Select (FFS) register to select and program the operating frequency of the PLL. This register can be programmed using a serial three-wire Interface (SPI) interface or by directly setting the frequency with resistor values.

The ICS650G-40LF has multiple main operational modes. The two most commonly used areNormal and Low Power modes. In Normal mode, the PLL is enabled and can be used to generate output clocks, while in Low Power mode, the PLL is disabled, resulting in lower power consumption. Additionally, ICS650G-40LF offers a slew rate control which allows the user to adjust the frequency settling time of the PLL output.

ICS650G-40LF features include frequency stability over a wide temperature range, a programmable on-chip oscillator (OCM), with a selectable pull-up/pull-down frequency, and low jitter outputs. Fast lock time and synchronization between multiple ICS650G-40LF devices is also possible.

Some of the applications for ICS650G-40LF include consumer electronics, communications, computer, industrial automation, and process control. Its low jitter, fast lock times, and stability over a wide range of temperature make it suitable for consumer applications, such as Digital Set-Top-Box (STB)s, and industrial applications such as factory automation, data communications, Ethernet switches, and wireless devices.

In conclusion, ICS650G-40LF is a versatile clock generator and frequency synthesizer constructed with a combination of clock output frequencies. It is designed to be cost-effective and provide better clock frequency stability for many types of applications. Its fast lock times, low jitter, and stability over a wide range of temperature make it an ideal choice for consumer, industrial, and process control applications.
