The ISPPAC-CLK5510V-01TN48I is an integrated PLL clock generator used for a variety of applications, from communications and networking platforms to high-performance computing and consumer electronics. It provides an easy-to-implement clock solution that delivers cost-effective system performance for multiple platforms and applications. The ISPPAC-CLK5510V-01TN48I integrates a frequency synthesizer with an ultra-low jitter PLL. It is designed to generate output frequency clocks with low jitter and cycle-to-cycle spread spectrum (SS) as specified by the platform’s application requirements.

The ISPPAC-CLK5510V-01TN48I supports four independent, programmable frequency output with duty cycles up to 75 Frequency and Spread Spectrum Functions with low jitter are available. A selectable programmable input clock can be used to generate the output frequency, or connected to an external oscillator. The internal clock synthesizer also provides a crystal oscillator output for use as a reference clock. The internal PLL is provided with evenly-spaced step adjustments from 25 MHz to 200 MHz and voltage-controlled crystal oscillator (VCO) for a wide range of output frequencies up to 1GHz.

The ISPPAC-CLK5510V-01TN48I enables use of spread spectrum techniques for EMI/EMF reduction, allowing the user to minimize RF interference. The phase locked loop technology used in the device provides highly stable, low jitter frequency conversion from a single low cost crystal oscillator. The ISPPAC-CLK5510V-01TN48I also features fast lock, low start up time and incorporates a programmable frequency, spread spectrum, and jitter correction.

The ISPPAC-CLK5510V-01TN48I works on the principle of a voltage-controlled oscillator (VCO). A VCO is an electronic circuit that is designed to generate an output frequency that is proportional to a varied input voltage. When the VCO receives a stable, low-frequency reference clock, it generates multiple higher-frequency clock outputs. The VCO is embedded with an oscillator, frequency divider, drivers, and phase-frequency detector (PFD).

The PFD compares the outputs of a voltage-controlled oscillator (VCO) with the reference clock and generates control signals for the oscillator. This feedback loop is maintained until all the outputs of the VCO are equal, thus forming a phase-locked loop. Within this loop, the ISPPAC-CLK5510V-01TN48I can be programmed to generate multiple output frequencies from a single reference clock and provide a wide range of output frequencies from 25 MHz to 200 MHz.

The ISPPAC-CLK5510V-01TN48I is suitable for various applications such as automotive, communications, and consumer electronics. Its wide output frequency range, fast lock time, low jitter, and excellent jitter spreading performance make it ideal for video and audio applications. Furthermore, it is capable of providing low EMI, making it suitable for wireless applications.

In conclusion, the ISPPAC-CLK5510V-01TN48I is an integrated clock generator designed for use in communications, consumer electronics, and other applications. It uses a voltage-controlled oscillator (VCO) and phase-locked loop innovative design to provide low jitter, excellent jitter spreading performance, and wide output frequency range from 25 MHz to 200 MHz. The device also helps to reduce RF interference with its spread spectrum techniques.
