The SI5338B-B02232-GM is a low-power, highly configurable clock chip from Silicon Laboratories (SiLabs). Specifically designed for use in broadcasting and audio/video applications, the SI5338B-B02232-GM is a remarkably capable clock chip, boasting features such as an on-board 32-bit processor, programmable output clocks, configurable asynchronous clocking and frequency synthesis, advanced jitter attenuators, serial EEPROM memory and configurable fanout.

As a clock chip, the SI5338B-B02232-GM belongs to the family of Application-Specific Clock/Timing devices. The main purpose of Application-Specific Clock/Timing devices is to provide synchronization of digital signals in high-speed digital systems. These devices are used in digital systems that require tight jitter performance, either in the form of input-output synchronization, data rate conversion, source-synchronous clocking, or a combination of all of these.

The primary goal of the SI5338B-B02232-GM is to provide a cost effective, low-power solution for broadcast and audio/video applications, so that all relevant signals in the system can be accurately synchronized. Additionally, the device is designed to optimize all relevant jitter requirements, both for input-output synchronization and for data rate conversion.

To make all of the above possible, the SI5338B-B02232-GM has a number of features that make it a very capable device. Central to its operation is the on-board 32-bit processor, which allows the device to be highly configurable and to access additional clock networks in less time than other competing devices. Additionally, the device includes two independent configurable input PLLs and four independent configurable output clocks, which can be programmed according to the desired application needs.

The SI5338B-B02232-GM also includes advanced jitter attenuators that greatly reduce jitter on the output clocks. This feature reduces the need for dedicated external jitter attenuators. Moreover, the device includes an on-board serial EEPROM memory that allows it to be configured for a variety of different applications, depending on the customer requirements. Additionally, the device features a configurable fan-out feature, allowing for an increase in system clock distribution.

By leveraging its 32-bit processor, advanced jitter attenuators, versatile configurability, and overall low-power design, the SI5338B-B02232-GM has set a new standard for Application-Specific Clock/Timing applications. The device is well suited for broadcast and audio/video applications, and its features make it an invaluable tool for any system that requires tight jitter performance.
