The SI5335B-B05215-GM is a high-performance, programmable clock generator from the Silicon Laboratories Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers family. It is designed to generate any frequency from 1.5 MHz to 2 GHz over a wide supply voltage range with world-class phase jitter.

The device integrates five high-performance analog PLLs, each of which can be used to generate any frequency up to 1GHz. The SI5335B-B05215-GM also supports up to four independent configurable differential outputs, or two independent differential or four single-ended outputs. In addition, the device supports a programmable spread spectrum generator on all outputs, making it ideal for generating low-EMI clock solutions.

The SI5335B-B05215-GM operates from a single 3.3V power supply and is packaged in a 24-pin, 5 x 5 mm QFN package. It allows for both negative and positive reference frequency (FREF) inputs, allowing for easy synchronization to external oscillators or clock sources. Furthermore, the device has a versatile programming interface, allowing for various levels of customization, such as frequency selection and output termination values.

The device works by using a unique set of analogs control signals and digital control logic to generate the desired frequency. The control signals are provided by the digital control logic, and the frequency is determined by a set of analog feedback signals, and the voltage or current that is applied to the negative or positive reference frequency inputs. Depending on the specific application, the PLL can be designed to generate any frequency of interest, in the range of 1.5 MHz to 2 GHz.

In addition, the SI5335B-B05215-GM provides a variety of features, such as programmable spread spectrum and programmable output drive strength. The spread spectrum feature reduces the peak to average ratio, making it well-suited for EMI sensitive applications. The programmable output drive strength feature allows for flexibility when making connections to external components, allowing for higher levels of generated frequency precision.

The SI5335B-B05215-GM is an ideal choice for applications such as cellular handsets, communications infrastructure systems, automotive and industrial applications, and any other applications that require high-frequency, low-noise timing solutions. It is designed to provide low jitter and very fast settling time, making it very suitable for a wide range of applications, including digital, analog and high-speed data acquisition systems.
