The ICS1524AMT is a low jitter, programmable clock generator designed for ASIC and FPGA systems. It features a wide frequency range of 1.5 to 250 MHz and is designed to support both a 3.3V and 5V power supply for ultra low power consumption.

The ICS1524AMT is the market leader in high performance, low noise clock generators and synthesizers. Utilizing advanced techniques such as PLL (Phase Locked Loop) Synthesizers, the device eliminates the need for costly quartz oscillators, which may require an expensive external temperature controlled transconductance amplifier for frequency stability.

The ICS1524AMT integrates a voltage controlled oscillator (VCO) and a programmable digital prescaler. The VCO is capable of achieving quite high frequency resolutions by utilizing a programmable prescale select input. Its high resolution allows it to create a wide range of frequency output. The device has an adjustable output current sink, which allows it to be used in multiple device designs.

The working principle of ICS1524AMT is simple, but effective. It consists of two sections: The PLL section and the Digital section. The PLL section contains a VCO, which is programmable by an external clock reference and a tuned output line and a phase detector which monitor the VCO output phase to the reference clock and correcting the phase error. The digital section controls the frequency of the output VCO using a programmable prescale select input. This prescale select input has a 16-bit resolution and allows for a wide range of frequencies to be generated.

The ICS1524AMT is typically used in digital television or digital video broadcast applications. It is capable of generating frequencies from 1.5MHz to 250MHz, allowing for applications requiring high resolution timing or synchronization. It can also be used in embedded systems for clock recovery, system timing and clocking. It is powered by either a 3.3V or 5V source, making it suitable for low power applications.

The ICS1524AMT is a perfect example of a clock generator, PLL, and frequency synthesizer. Offering a wide range of frequencies and resolution, along with a low power supply design, it is an ideal choice for applications requiring high stability and accuracy. Additionally, its programmable nature adds versatility and cost savings over costly quartz oscillators.
