SI5351C-B06352-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5351C-B06352-GM is an I2C-programmable CMOS clock generator from Skyworks Solutions, designed to replace crystals, oscillators, and PLLs. It features a 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 input (CLKIN) ranging from 10 to 100 MHz. It provides eight LVCMOS outputs in a 20-QFN package, operating within a core supply voltage range of 2.25 V to 3.6 V and an output supply range of 1.71 V to 3.6 V. Typical period jitter is less than 70 ps peak-to-peak.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the suffix B06352 using ClockBuilder Pro software or official Skyworks documentation before procurement. Confirm that the required external crystal frequency matches the device's supported inputs. Ensure the design supports the necessary I2C interface levels and power sequencing requirements for reliable operation.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this variant when synchronization to an external reference clock is required rather than free-running internal oscillator operation. Verify that the application requires eight independent clock outputs. Ensure the system design accommodates the 20-QFN package footprint and thermal dissipation characteristics specified in the datasheet.
