The SI53321-B-GM is a versatile and powerful clock buffer, driver and splitter. It is a low-jitter, 3.3V, wide-input-range clock buffer, driver and splitter specifically designed for clock and data distribution in high-performance computing applications. The SI53321-B-GM is designed to meet stringent requirements for clock stability, performance and noise immunity. It can accept input frequencies from 2 kHz to 750 MHz and output frequencies from 2 kHz to 1 GHz with less than 0.2% jitter.

SI53321-B-GM provides four selectable signal types: two differential outputs (HCSL or 3-state) and two single-ended buffered outputs. It has up to four dedicated outputs with adjustable fan-out from the input clock signals, allowing systems designers to implement fan-out and signal conditioning networks with a single device.

The SI53321-B-GM is ideal for use in system architectures that require an input clock with a wide range of frequencies and an ultra-low-jitter clock signal with a wide fan-out buffer. It is optimized for applications in high-performance computing, telecommunications, consumer audio and video, storage, networking, and high-speed data distribution systems. It\'s also suitable for system clocks with multi-lane outputs.

The SI53321-B-GM is a versatile clock buffer, driver, and splitter that provides a wide range of features and benefits in a robust, low-jitter, 3.3V-compatible package. With its wide input/output frequency range and its impressive jitter performance, it is ideally suited for clock and data distribution applications in environments requiring low-jitter operation. This device has multiple selectable signal types and can achieve fan-out up to 32:1 from the input clock, making it the ideal choice for systems requiring large fan-out capabilities.

The SI53321-B-GM\'s working principle is based on two basic principles: first, it samples the input clock signal and converts it into a digital data stream; second, it outputs the digital data in the requested format. Sampling is achieved by using a phase locked loop circuit, which locks in to the input clock signal and adjusts the output frequency accordingly. Then the digital data is converted into the selected output format and sent to the output buffer. The output buffer is designed to meet a wide range of applications from low to high speed, as well as from single to multiple lane outputs. This allows the SI53321-B-GM to meet a wide range of system requirements.

In summary, the SI53321-B-GM is a highly versatile clock buffer, driver and splitter with a wide input/output frequency range, low-jitter performance, and the capability to generate multiple outputs. It is the ideal choice for clock and data distribution applications in high-performance computing and other environments where low jitter operation is required.
