IDT5T9891NLI is a silicon clock generator device that provides a cost-efficient single-chip solution for clock and oscillator requirements in various applications. The device integrates a phase-locked loop (PLL), low phase noise VCO, on-chip voltage controlled oscillator (VCO), and programmable output drivers and is suitable for various applications including communications systems, broadcast systems, and data storage systems. This article will provide an overview of the IDT5T9891NLI\'s application field, working principle and its advantages.

The IDT5T9891NLI is used primarily for clock and frequency synthesis applications for high-speed data communications, network synchronization, broadcast systems, and data storage systems. Its capabilities allow for frequency or clock synthesis from its on-chip low phase noise voltage controlled oscillator (VCO). This makes it suitable for applications requiring low jitter, stable and low phase noise outputs. Its features also make it ideal for creating multiple frequencies from a single oscillator for systems demanding multiple, highly accurate frequency signals.

The IDT5T9891NLI is based on a PLL and uses a reference clock (REF) from a crystal oscillator or an external clock source to generate an output signal with an adjustable frequency range. The device has three programmable outputs and each of these output frequencies is determined by a single, programmable feedback frequency. This feedback frequency is also generated by a VCO in order to maintain a constant output frequency. The VCO gain and bandwidth are adjustable and the VCO can be tuned over a wide frequency range.

The adjustable feedback frequency allows the system architect to select the desired output frequency by programming the frequency divider, the pre-divider, and the VCO select bits. The reference clock and the VCO are fed into the phase detector along with the output from the dividers. The phase detector will compare the phase and frequency of the reference clock and the VCO and generate a voltage control signal to adjust the VCO frequency. The output signal is then generated from the VCO at whatever frequency is determined by the feedback loop.

The IDT5T9891NLI is an efficient clock generator and synthesizer. With its integrated PLL, adjustable VCO frequency range, adjustable output drive and low jitter, it is ideal for a variety of clock generator applications. It is also configurable for multiple output combinations providing flexible frequency synthesis and jitter cleaning capabilities. These features make it ideal for a variety of data communications, data storage, networking, broadcast, and a variety of commercial and industrial applications.

The IDT5T9891NLI also has various advantages over competing products. It offers low jitter, low power consumption, and excellent phase noise and spectral purity. Its packaged form factor is also compact and has excellent thermal characteristics. This makes it suitable for portable applications where size and cost are important considerations.

In summary, the IDT5T9891NLI is an efficient single-chip clock generator and frequency synthesizer that provides a cost-effective solution for clock and oscillator requirements in various applications. With its integrated PLL, adjustable VCO frequency range, adjustable output drive and low jitter, it is ideal for a variety of clock generator applications. Its features make it an excellent choice for a variety of applications including high-speed data communications, network synchronization, broadcast systems, and data storage systems.
