Technical Specifications

The ICS552G-03I typically supports multiple output clocks, each capable of driving different system components. It uses a Phase-Locked Loop (PLL) to multiply the reference clock frequency and generate the desired output frequencies. The output clock frequencies are often programmable via external pins or a serial interface. The device operates on a 3.3V power supply and is available in various package options, such as TSSOP (Thin Shrink Small Outline Package). The low jitter performance ensures signal integrity in high-speed digital systems.

This clock generator is frequently employed in systems where multiple clock frequencies are required, such as computers, networking devices, and embedded systems. Its ability to generate precise timing signals helps to optimize system performance and reduce timing-related errors. The programmable outputs allow designers to tailor the clock frequencies to meet the specific requirements of their applications. The low jitter characteristic is particularly important in high-speed systems where signal integrity is critical.
