ICS271PGT is a high-performance Clock/Timing solution for various Clock Generator, PLL, and Frequency Synthesizer applications. It comprises one master oscillator and one or more phase-locked loops (PLLs) with an integrated voltage-controlled oscillator (VCO) and an internal divider system. It provides an output frequency from 3.2 to 43 MHz. It offers enhanced features, including phase shift and on-chip programmable frequency-division. The device is operable with a supply voltage range of 4.5 V to 5.5 V, and is offered in the industry-standard TQFP64 package.

The ICS271PGT is designed especially for designs that require jitter and frequency accuracy in the 3.2 to 43MHz range. Nowadays, low-jitter Clock Generators, PLLs, and Frequency Synthesizers are increasingly becoming a necessity in a wide variety of applications, ranging from digital communications systems to consumer electronics. With the ICS271PGT, engineers can reduce cost and design time by combining multiple Clock/Timing circuitry into a single solution. Moreover, its integrated VCO, dual PLLs, and other performance enhancing features offer superior jitter and frequency accuracy for a variety of applications.

At a basic level, the ICS271PGT is a dual-PLL solution that consists of a master oscillator, two PLLs (a main and a calibration PLL), and a programmable frequency-division system. The ICS271PGT is mainly used in design to help reduce clock jitter and frequency accuracy requirements. The Master Oscillator in the ICS271PGT determines the reference clock that is split into two paths: the Main PLL and Calibration PLL.

The Main PLL is the fundamental clock generator in the ICS271PGT, with a direct connection to the device’s output. The frequency-division circuit in the device then actives the output clocks divided by some ratio of the Input Reference Frequency. The Main PLL is also capable of phase-shifting the input signal, which helps reduce jitter. The Calibration PLL provides wide frequency tuning capabilities and is typically where the output frequency is set. When configured for jitter attenuation, it helps to minimize the variability and peak-to-peak jitter of the Main PLL’s output clock.

The ICS271PGT offers a number of advantages, such as the ability to output multiple frequencies at the same time, wide frequency-tuning range, plus phase-shifting capabilities. It offers an incredibly low power consumption level of only 4.5 V to 5.5 V, and is available in the popular TQFP64 package. This device also supports spread-spectrum, allowing faster frequency transmission for enhanced jitter and noise characteristics – great for meeting critical performance requirements.

Overall, the ICS271PGT is an excellent choice for Clock Generators, PLLs, and Frequency Synthesizers in applications requiring jitter and frequency accuracy. With its integrated VCO, dual PLLs and frequency-division system, it offers superior jitter and frequency accuracy for various applications, and is available in a low-power, industry-standard package for easy integration.
