ICS280PG is a high performance, low power programmable clock generator offering designers flexibility and precision. It is typically used in microprocessor systems, communications systems, FPGA and ASIC designs, and other applications where programming and customization are desired. ICS280PG is available in a variety of packages, including a small footprint dual-in-line (DIP) package with an extended temperature range.

The ICS280PG has an abundance of features to help customize an application with flexibility. It can generate clock frequencies between 8 kHz and 1 GHz and can support up to 3 clock outputs. The device also allows for custom clock programming and features such as spread spectrum, power on reset control, skew control, and a programmable oscillator range.

The ICS280PG uses a Phase Locked Loop (PLL) to generate oscillations. A PLL is an electronic circuit which produces an output signal with a frequency that is a fixed multiple of an input signal. The PLL is locked on to the input frequency and generates an output signal with frequencies expressed as a multiple of its input. The multiplier determines how many times the input frequency is multiplied to calculate the output frequency. The ICS280PG is able to accurately reference a input frequency or recover a reference clock over a range of frequencies.

The ICS280PG uses a Variable Frequency Oscillator (VFO) instead of a conventional crystal oscillator. The VFO contains a frequency synthesizer which is used to develop a wide range of frequencies from a small set of crystal frequency sources. The VFO produces higher precision results than a conventional oscillator, due to the high level of accuracy and stability in the frequency synthesis process. This allows for a variety of specific clock frequencies to be synthesized, without the need for additional external crystals.

The ICS280PG implements many features to enhance output accuracy and reduce the risk of jitter. It offers a pre-programmable range of clock frequency cycles to optimize the output jitter. It also utilizes a high precision oscillator to reduce the timing error associated with crystal oscillators. Finally, it offers an integrated Spread Spectrum feature which allows the user to spread out the peak power of the clock signal over a frequency band. Spreading out the peak power reduces the amount of noise and jitter found in clock signals.

The ICS280PG is ideal for a wide range of applications requiring a configurable and precise clock source. It is particularly suited for use in embedded systems, communications systems, FPGA and ASIC designs, and other applications where a programmable clock generator is desired. It provides low power, high performance and exceptional accuracy, making it an ideal choice for those looking for a programmable clock generator.
