SI5351C-B02659-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5351C-B02659-GM is an I2C-programmable CMOS clock generator from the Si5351 family, manufactured by Skyworks Solutions. It features a PLL/VCXO and MultiSynth fractional divider architecture capable of generating any frequency up to 200 MHz with 0 ppm error on each output. The device synchronizes to an external reference clock (CLKIN) ranging from 10 to 100 MHz or a fixed-frequency crystal (25 or 27 MHz). It provides eight LVCMOS outputs in a 20-QFN package, supporting independent core and output supply voltages for level translation.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed code associated with the suffix B02659 against the required system clock specifications. Confirm that the 20-QFN package dimensions match the target PCB land pattern. Ensure the design supports the recommended operating temperature range and voltage levels specified in the datasheet.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when synchronization to an external reference clock is required, distinguishing it from the free-running Si5351A. Verify that the application requires eight outputs, as other variants offer fewer channels. Consider the power supply requirements for both VDD and VDDOx domains during the initial design phase.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5351 series, which includes variants A, B, and C. The 'C' designation indicates support for an external clock input (CLKIN), while the 'B' in the middle denotes the specific package type or revision within the datasheet context. The part replaces discrete crystals, oscillators, and PLLs in cost-sensitive designs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements include other Si5351C variants such as SI5351C-B-GM or SI5351C-Bxxxxx-GM if custom programming is needed. For applications requiring different output counts, consider the Si5351A or Si5351B series with appropriate pinout compatibility.
