ICS276PGI

Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

The ICS276PGI is a low EMI and low jitter differential PLL synthesizer with I2C interface from Integrated Circuit Systems (ICS). It comprises an integer-N dual-modulus PLL and a low jitter, programmable output frequency divider, and integrates divided VCO, loop filters, synthesizer, I2C interface, differential output drivers and phase detector in one chip. It has zero phase noise and low jitter across any frequency within its range. The ICS276PGI is capable of delivering robust performance while minimizing power consumption and thereby reducing EMI. This makes it highly suitable for embedded and mobile applications such as phones, GPS, and portable media players.

The ICS276PGI is a highly programmable device used as a clock generator, PLL, frequency synthesizer, and more. It offers an ultra-wide frequency range of 74 kHz to about 381 MHz with a wide frequency step resolution for a maximum of four clock outputs. It is ideal for applications requiring different frequency settings to be generated from multiple outputs, as the outputs can be individually programmed for the desired frequency range. The device also has an I2C interface for programming and monitoring, allowing easy and efficient control of multiple configurations. In addition, it has built in power down and low power settings that ensure maximum power efficiency.

In addition to its clock generation functions, the ICS276PGI has several features designed to improve jitter and phase noise performance. It features advanced, low-noise output drivers, to reduce the influence of power supply noise, while an advanced loop-filter design helps to ensure a low-phase noise operation. The device also has EMI reduction features, such as an on-chip spread-spectrum clock generator, to minimise radiated EMI. The low-power design is also ideal for mobile and embedded applications, as power-savings reduce heat, noise and battery usage.

The ICS276PGI is a highly versatile device, capable of providing a wide range of output frequencies with a programmable, fast switching capability. This makes it well suited to applications such as set-top boxes, HDTVs and car audio systems, where a range of different frequencies are often needed from a single device. Its advanced output drivers, EMI-reduction features and low-phase noise design allow for reliable and low-noise performance in a variety of applications.

For a device that offers reliable, low-noise performance across a wide frequency range and a range of features designed to minimise power consumption and EMI, the ICS276PGI is an ideal choice. The ICS276PGI is an efficient and cost-effective solution for clock generation and frequency synthesis applications, offering highly programmable frequency output with low jitter and phase noise performance. As such, it is ideal for embedded, mobile, set-top box and car audio applications.
