The ICS954141AGLFT is a clock/timing special application integrated circuit (IC). It is specially designed for applications that require precise timing stimulus or response. It provides precise clock/timing signals across multiple clock domains, and can accurately synchronize video, audio, and other signals.

The ICS954141AGLFT integrates high-density, low-skew, low-jitter clock-and-data recovery (CDR) and clock/timing signalling features to enable precise multi-wire applications. The integrated features include a highly precise, low speed frequency monitor (0.001 Hz to 200 MHz), a wide range of programmable input-clock and output-clock frequencies, on-board temperature measurement (with accuracy of -40°C to +85°C), and an optional auto-correlation algorithm. This significantly reduces the need for manual or operator-assisted configuration changes.

The key application field of the ICS954141AGLFT is the precise timing stimulus or response that is required in data communication and broadcasting, such as 4K/Ultra-HD TV broadcasting and wireless communication. Other applications include audio/video sync, clock/timing synchronization/conformance, multi-phase-shift keying modulation, and test & measurement.

The ICS954141AGLFT is equipped with a built-in high-speed programmable frequency synthesizer that enables the chip to generate and operate at a wide range of frequencies. Its unique high-speed programmable frequency synthesizer reduces the traditional, external clock frequency generation circuitry, and simplifies the design, enabling the ICS954141AGLFT to be used easily in a variety of application fields.

In terms of working principle, the ICS954141AGLFT works by combining the input clock frequency (oscillator) and output clock frequency (PLL) signals and applying the Clock and Data Recovery (CDR) process to them. This process involves the detection of edges and transitions in the input clock and data signals. The integrated PLL then modulates and shifts the frequency of the output clock frequency to match that of the input clock frequency.

In conclusion, the ICS954141AGLFT is a specialized clock/timing integrated circuit for applications that require precise timing stimulus or response. Its key application fields include 4K/Ultra-HD TV broadcasting and wireless communication, audio/video sync, clock/timing synchronization/conformance, multi-phase-shift keying modulation, and test & measurement. The ICS954141AGLFT works by combining the input clock frequency and output clock frequency signals and applying the Clock and Data Recovery process.
