The SI53326-B-GM clock buffer from Silicon Labs is a differential output two-to-four fanout buffer. It is designed to spread a single, low-skew, low-jitter differential clock signal across multiple fan-out outputs while maintaining low-jitter timing margins. It is ideal for applications such as broadband video, video over IP and consumer appliances, where very low jitter and small device size are essential. The SI53326-B-GM is available in a small-footprint 4 mm × 4 mm 24-pin QFN package.

The SI53326-B-GM is part of Silicon Labs’ family of low-jitter clock buffers and fanout buffers. This chip operates from a single-ended signal, with 1.2V to 3.3V input voltage, making it suitable for most systems. It provides two differential output clocks, each individually clock-enabled, and two additional single-ended clocks. It also offers a low additive jitter of 0.4ps, making it ideal for demanding, high-frequency applications.

In terms of its application field, the SI53326-B-GM is particularly well-suited to high-bandwidth audio/video transfer and streaming applications such as digital video over IP, digital audio and digital video over coaxial cable, digital audio over HDMI, etc. The low additive jitter offered by the SI53326-B-GM is essential for ensuring clean, uncompressed audio/video signals. The SI53326-B-GM is also suitable for other applications such as computer systems, communication systems, home appliances, etc. It is also suitable for automotive systems, providing reliable, low-clock jitter clock buffers.

The SI53326-B-GM clock buffer operates via the I2C protocol, allowing for programming of the output clocks. Programming is done using an external master controller, such as an MCU, allowing for flexible and dynamic control of the output clocks. This is useful for situations where the output clocks must be dynamically changed depending on the requirements of the system.

The SI53326-B-GM clock buffer is highly integrated, with a wide range of features such as a low-clocking jitter of 0.4ps, a single-ended input voltage range of 1.2V to 3.3V and differential output voltage. It also features a tight phase lock loop and a wide input frequency range of up to 200GHz. In short, the SI53326-B-GM provides a highly robust clock solution for a wide variety of applications.

The SI53326-B-GM from Silicon Labs offers both differential and single-ended output clocks, as well as programming capabilities for maximum system flexibility. It is an optimal choice for applications requiring low jitter, small size and low power. The SI53326-B-GM is an ideal solution for high-speed data transfer and video applications, providing reliable low-jitter clock solutions.
