The ICS954229AGT device, part of the Clock/Timing product family, is designed to provide a reliable way to manage major frequency and output signal needs for next-generation applications, such as mobile computing and communications, automotive, industrial and robotics. The ICS9542929AGT is a universal phase-locked loop with an embedded phase-locked loop (PLL) core, phase frequency detector (PFD) and clock buffer system. It is ideal for applications with multi-GHz carrier frequencies, such as those required in high-speed communication interface standards such as PCI Express, SATA and gigabit Ethernet. Its advanced features make it suitable for a wide range of applications.

The ICS954229AGT device has several major components, which can be grouped into two main categories: control components, such as the phase-locked loop (PLL), phase frequency detector (PFD), and charge pump and output components, such as the clock buffer system, programmable frequency divider, and jitter cleaner. Each of these components is designed to perform a specific task within the device, together yielding the desired overall performance.

The PLL is responsible for locking a system clock to a desired reference frequency. It consists of a phase-locked loop core, reference divider, and voltage-controlled oscillator (VCO). The PFD is responsible for monitoring the phase and frequency of the reference and system clocks, and comparing the differences between them. The PFD then provides a proper control voltage to the VCO in order to adjust the system clock to match the reference clock. The PFD also features a programmable dead-time control that can be used to enable or disable the PFD to reduce noise in the system.

The clock buffer system is responsible for providing a low-jitter, high-performance clock to downstream blocks. It consists of a variable output buffer, programmable frequency divider, and jitter cleaner. The variable output buffer is used to adjust the voltage levels of the output clock signals, while the frequency divider is used to divide the reference frequency of the PLL to create one or more output clocks. The jitter cleaner is an optional on-chip feature designed to reduce the jitter of the output clocks. Additionally, the ICS954229AGT device supports multiple clock outputs with different frequencies.

The ICS954229AGT device is optimized for next-generation applications where reliable, high-performance clock management is essential. With its advanced features, it is well-suited for applications in both commercial and automotive markets. It provides a low-jitter, wideband PLL as well as a programmable frequency divider, and is capable of delivering multiple clock outputs with varying frequencies. Furthermore, its highly integrated architecture simplifies the overall design effort, allowing designers to quickly and efficiently integrate it into their systems.
