The ICS8442AYILFT is a highly flexible clock generator that provides quick and reliable system and solution design. It has a range of applications in Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers. This article will cover the application field and working principle of the ICS8442AYILFT.

The ICS8442AYILFT is a low power programmable clock generator capable of outputting multiple Clocks up to 400MHz with a low jitter performance of 0.8ps RMS. It offers control and flexibility with an advanced I2C interface with up to 204 bits per clock cycle. The fully programmable device has an 8MHz reference clock frequency on the CLKD input. It is perfect for applications needing seamless production test and characterization for volume manufacturing.

The ICS8442AYILFT has a wide selection of popular output frequencies, multiple output banks for easy frequency management and independent control over each output. It offers a variety of features including SATA compliant output APIs with slew control and wide tolerance of input clocks. It also supports data rate fully compliant with S(F)PDDR, HMC, GPON, and HDMI interfaces.

The ICS8442AYILFT is capable of generating fractional and multiply synthesized frequencies up to 400MHz with a low jitter performance of 0.8ps RMS. It is ideal for use in high speed designs requiring up to 10x timing budget to account for jitter and latency budgeting. Its features include reverse/mirroring of an input clock as an output, tracking of an external external reference clock, preemphasis control, and dual loop PLLs — all of which can be programmed through an I2C control interface.

The ICS8442AYILFT uses dual-loop PLL architecture, which is composed of two PLLs. The first PLL (VCO) is used for synthesizing the output frequency which is further divided by a divider. The second PLL (VCO2) is used for fractional-N/ fractional-P synthesis. This architecture can improve the intrinsic jitter performance and makes it suitable for high speed application such as SERDES or GBIC/XFP. The dual-loop architecture can also reduce the output clock jitter up to 16x over a standard PLL.

The ICS8442AYILFT offers a variety of features and flexibility, making it suitable for applications requiring quick and reliable system designs. It is capable of providing multiple clocks up to 400MHz with a low jitter performance of 0.8ps RMS. It supports data rate compliant with multiple interfaces including S(F)PDDR, HMC, GPON, and HDMI, and is perfect for applications needing seamless production test and characterization for volume manufacturing. The dual-loop PLL architecture ensures improved sustainability and lower power consumption, making the ICS8442AYILFT an ideal choice for high-performance Clock/Timing applications.
