Clock/timing systems are an integral part of a variety of applications and technologies. These systems are used to measure time and coordinate the activity of multiple tasks. In an effort to meet the ever-increasing demand for precision and accuracy, specialty clock and timing products, such as the ICS9248AG-92LFT, have been developed to address specific application needs. This article provides an overview of the ICS9248AG-92LFT application field and its working principle.

Application field

The ICS9248AG-92LFT is a high-performance clock generator suitable for a variety of precision clock applications, such as broadcast audio and video. It is ideal for use in HDTV-compatible systems where precise clocking is critical. The ICS9248AG-92LFT offers a unique blend of features, which includes super-low jitter performance, a wide frequency range, integrated DPCS (Digital Phase-Locked Loop System) for precise clock synchronization, a PLL for robust frequency and low-jitter audio clock production, programmability for splice time, time-stamp, frame-rate alignment and synchronization, and IEC-60958 (AC-3/Dolby Digital audio) and breakaway audio support.

The ICS9248AG-92LFT is also a particularly good choice for wireless microphone applications. Its DPCS technology allows for the precise clock synchronization and phase alignment of microphones distributed throughout a stage or studio, as well as its ability to support timing requirements for medium to high latency environments. It is also compatible with basic QoS (Quality of Service) packet forwarding rules, and provides features such as packet size metering and rate limiting.

Working principle

The ICS9248AG-92LFT uses a crystal oscillator as its timing reference. This oscillator produces a signal with a frequency that can be measured and regulated using the ICS9248AG-92LFT\'s control logic unit. The control logic unit is responsible for controlling the frequency of the clock signal, as well as for generating clock signals with low jitter, precision, and low noise. The clock signal is fed into a phase-locked loop (PLL) circuit that adjusts the frequency of the clock signal, ensuring that it is always in sync with the reference frequency.

The ICS9248AG-92LFT also incorporates Digital Phase-Locked Loop (DPCS) technology for precise clock synchronization and phase alignment. This technology allows for the synchronization of multiple clocks and enables the ICS9248AG-92LFT to support low latency requirements. In addition, the ICS9248AG-92LFT features a wide frequency range, programmability for splice time, time stamp, frame rate alignment and synchronization, and IEC-60958 (AC-3/Dolby Digital audio) and breakaway audio support.

The ICS9248AG-92LFT is capable of providing a wide range of clock frequencies, making it suitable for a variety of applications. Furthermore, its high-performance clock generator ensures that the clock signal generated is highly reliable, with minimal jitter and low noise. This ensures that the signal is of consistently high quality, no matter what the environment.

In conclusion, the ICS9248AG-92LFT is an ideal choice for both broadcast audio and video applications, as well as wireless microphone applications. It offers a unique combination of features, such as super-low jitter performance, a wide frequency range, integrated DPCS, and IEC-60958 (AC-3/Dolby Digital) audio support. It also features programmability and low-latency support, making it a reliable and versatile timing solution in a variety of applications.
