It also provides external frequency-synthesis versatility, high-jitter immunity, low-power consumption, and a small package.

Application field

The ICS7151MI-40LF clock generator has become increasingly popular in communication and storage systems due to the extremely low-jitter, high-frequency-multiplication ratio, and low-power consumption. It is a very reliable clock solution for high reliability requirements from switches, routers, bridges, servers, and storage devices. Furthermore, due to its low-cost and small package, it becomes the perfect solution for various System-on-Chips (SoC), multi-function telecommunication and consumer products.

Working principle

The ICS7151MI-40LF device utilizes a PLL-based structure to achieve high-frequency multiplication. It combines a low jitter oscillator, a wide input reference frequency range, and a low noise charge pump to provide the sub-system with a high quality clock signal. The oscillator provides the hardware with a stable frequency output of up to 40 MHz and combines it with a charge-pump circuit to reduce the jitter to below 100ps. The input reference frequency can range from 1MHz to 600MHz, ensuring the device can cover a wide range of frequencies. The PLL includes a fast-lock frequency-synthesis mechanism that allows a wide range of adjustable frequencies with low jitter under 50ps. Finally, the device is featured with low-power consumption and small package size, making it ideal for various system-on-chip designs.

In conclusion, the ICS7151MI-40LF is a highly configurable and reliable system clock generator, PLL, frequency synthesizer and frequency multiplier device, ideal for Systems-on-Chip (SoC), microprocessor and communication systems. It provides a low jitter clock source with a high frequency multiplication ratio of up to 40 times, offering a wide range of external frequency synthesis, low noise, low power consumption, and a small package.
