ICS843034AY-01LF is a clock generator and synthesizer designed for clocking and timing circuits in high performance applications. It enables low-bandwidth, low-power operation while providing a flexible interface between two clock domains.

Application Field

The ICS843034AY-01LF is suitable for a wide range of clock applications, including communications, server and PC motherboards, embedded microprocessor systems, and digital signal processing. Additionally, it is well-suited for clocking frequency synthesizers, digital signal processors and video playback.

The ICS843034AY-01LF features a high-performance differential output stage, which can easily be adapted to different transmission types, such as LVPECL, LVDS, and CML. This adjustment makes it possible to use the same clock source for different system architectures.

Its flexible design also allows multiple clocks to be derived from the same clock source, providing system designers with the flexibility to design a highly complex timing architecture.

Working Principle

The ICS843034AY-01LF uses a differential PLL architecture to generate two different clock outputs from a single reference clock input. The different outputs can be clocked from different reference frequencies and configured to independent output frequency settings. To achieve this, the device uses a programmable feedback divider and a pair of Voltage Controllled Oscillators (VCOs) to divide the external reference input frequency. The VCOs are then connected to form a feedback loop, which allows for fine tuning of the output frequency to match specific system requirements.

The ICS843034AY-01LF features a low-jitter output and is designed to minimize system noise and maximize system performance. Additionally, its low-power, high-bandwidth differential output stage makes it suitable for a wide range of applications. It can also be used in applications where a high-performance differential output stage is required.

The ICS843034AY-01LF also incorporates an on-chip phase-locked loop (PLL), which enables high-precision timing and phase-alignment. This feature ensures that all clock cycles with the same frequency are precisely aligned. Furthermore, the device includes a programmable output divider that can be used to adjust the output frequency and an integrated power base for improved VCO tuning accuracy.

In addition to its various features, the ICS843034AY-01LF also offers a variety of advanced features, including spread spectrum clock technology, programmable output slew rate, specific PSiP compatibility, selectable phase alignment, digital control and monitoring capability, and more.

Conclusion

The ICS843034AY-01LF is a highly versatile clock generator and synthesizer designed for clocking and timing applications. It offers a flexible interface between two clock domains and enables low-bandwidth, low-power operation. The device also features a high-performance differential output stage, which can easily be adapted to different transmission types. Additionally, it incorporates an on-chip PLL, programmable feedback divider, and output divider, providing system designers with the flexibility to design a highly complex timing architecture. Thus, it is suitable for a wide range of clock applications such as communications, servers, microprocessors, and digital signal processing.
