ICS8432BK-51LFT

The ICS8432BK-51LFT is a programmable clock generator which provides superior jitter performance for a wide range of general clock applications. This product features a programmable oscillator array in a compact hermetic package and is suitable for both commercial and industrial temperature range designs. It is the ideal solution for applications needing frequency synthesis, high speed clock replication, or stable low jitter clock generation.

Application Field

The ICS8432BK-51LFT can be used in a wide range of applications, including networking and telecommunications, as well as high-performance computing, display, and storage systems. Typical applications include network switches, routers, HDD controllers, FPGAs, ASICs, and memory controllers. The device is particularly suited to applications where tight timing and jitter control is required, such as in the design of Ethernet switches, routers and other high-speed communication equipment.

Working Principle

The ICS8432BK-51LFT utilizes a high-accuracy programmable oscillator array, permitting customization of frequency and jitter performance characteristics to adapt the device to different system and customer requirements. The ICS8432BK-51LFT employs state-of-the-art algorithms to track the variable frequency oscillator, curing the jitter to provide a low jitter clock output. The device also incorporates a slew-rate-controlled slew-rate-controller implementation to provide robust jitter control.

The ICS8432BK-51LFT also features a power-optimized delta-sigma modulator design to accurately synthesize and control frequency. This architecture allows the clock generator to switch between pre-programmed frequencies while minimizing output jitter. The modulator tracks each frequency across the input clock frequency range and automatically selects the best performing frequency. The output frequency is determined by a set of parameters that can be programmed through the I2C interface, such as the VCO frequency range, the VCO gain, and the VCO start-up frequency.

The device is designed to provide improved system performance in a wide variety of applications. Its jitter performance is suitable for a variety of high speed clocks, such as DDR4 and volatile memory, high-speed interfacing, and even for clock synchronization applications. Its power-adjusted delta-sigma modulator and frequency-tracking algorithms allow it to provide a robust and low-noise signal that is optimized for performance and jitter control.
