MAX31180AUA+

The MAX31180AUA+ is a versatile clock generator and frequency synthesizer from Maxim Integrated. It is designed to provide a flexible and cost-effective solution for clocking needs in a variety of applications. The MAX31180AUA+ combines an all-digital clock generator, a phase-locked loop (PLL), and a frequency synthesizer in an integrated circuit. It is capable of generating clock frequencies up to 400MHz, making it an ideal solution for use in high-speed digital systems.

The MAX31180AUA+ is capable of generating clock frequencies from 1kHz up to 400MHz. The device supports a wide array of input frequencies, from 0.25MHz up to 400MHz, and can synthesize up to four output clocks with a maximum frequency of 400MHz. It has four different PLLs that can be used either independently or as part of a multi-PLL system for better phase noise and jitter performance. The device also includes a wide range of other features, including output voltage level and spread spectrum control, noise shaping and phase compensation, output divider ratio selection, and phase delay control.

The main benefit of the MAX31180AUA+ is its ability to provide both clock generation and frequency synthesis in a single integrated circuit. By integrating these two functionalities, the device can be used to generate multiple clocks or synthesize a single clock of any desired frequency. This makes the MAX31180AUA+ an ideal solution for applications requiring complex clocking requirements such as multi-passprocessor systems and system-on-chip designs.

The MAX31180AUA+ is powered from a single +3.3V rail, making it ideal for many of today’s applications. It also includes a low-voltage power down mode for power-sensitive applications.
