The ICS570A is a versatile clock generator, phase-locked loop (PLL) and frequency synthesizer produced by IDT. This device is especially suited for use in low power field programmable logic controllers (FPLAs), which require low cost timing solutions but need to achieve excellent performance. It can be used to generate integrated frequencies up to 350 MHz and typically consumes just 5 mW of power.The ICS570A provides two core components: analog and digital blocks. The analog block provides the necessary control signals and clocking signals to control an external FPLA. It consists of an oscillator, a voltage-controlled oscillator (VCO), and dividers to produce the required frequencies. The digital block contains a PLL and several digital blocks, including a digital low-pass filter and digital divider, to provide additional functions and flexibility.The ICS570A also provides a range of features that make it suitable for various applications. For example, it has an integrated voltage-controlled oscillator (VCO) that can be used to generate reference frequencies from the internal oscillator. It also has a range of frequency dividers, including up to 6-bit dividers for generating custom frequencies, as well as an integrated low-pass filter for reducing jitter and providing cleaner clocking signals.The ICS570A also provides a single-wire high-speed serial interface (HSSI) for externally controlling the VCO, PLL and dividers. This makes it possible to program the ICS570A remotely, which is useful when used in embedded systems.In addition, the ICS570A can be used to generate frequency synthesis signals. It has an integrated synthesizer that can be programmed to generate frequencies up to 350 MHz. This makes the ICS570A suitable for applications that require high clock signal accuracy, such as providing timing signals for FPLAs.In terms of performance, the ICS570A can be used to generate clock signals with jitter performance below 0.2ps, and has a very low in-band phase noise of -145 dBc/Hz. This makes it suitable for a wide range of timing requirements, from data-communications applications to FPGAs.Overall, the ICS570A is a versatile clock generator, PLL and frequency synthesizer. It is suitable for use in embedded systems requiring low power but excellent performance, and can be programmed easily via its high-speed serial interface. It is also capable of generating frequency synthesis signals up to 350 MHz, making it ideal for FPLAs, data-communications applications and other demanding timing requirements.
