SI5350C-B05109-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B05109-GT is a factory-programmable CMOS clock generator manufactured by Skyworks Solutions. It utilizes a dual PLL and MultiSynth fractional divider architecture to generate up to eight non-integer-related frequencies ranging from 2.5 kHz to 200 MHz with 0 ppm error. The device supports glitchless frequency changes, configurable spread spectrum, and static phase offsets. It operates on core and output supply voltages of 1.8 V, 2.5 V, or 3.3 V. This specific part number indicates a configuration for the 10-MSOP package, which provides three LVCMOS outputs.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the factory-programmed configuration matches the required system timing specifications before integration. Confirm that the 10-MSOP package variant aligns with the target PCB land pattern and pinout requirements. Ensure the selected crystal frequency (25 MHz or 27 MHz) corresponds to the programmed reference input settings defined in the datasheet.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-frequency solution is preferred over I2C programmability to simplify board design. Choose the 10-MSOP package if only three output clocks are necessary for the application. Verify that the required output frequencies fall within the 2.5 kHz to 200 MHz range and that the voltage levels match the available 1.8 V, 2.5 V, or 3.3 V supplies.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device belongs to the Si5350 family of clock generators, which offers factory-programmable custom timing solutions. Unlike the Si5351 series, which supports I2C reconfiguration, the Si5350C relies on pin-based control and pre-programmed internal registers. The 'B' suffix denotes the specific silicon revision and feature set compatible with the described electrical characteristics.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350C variants with different factory programming codes but identical package types. For applications requiring I2C configurability, the Si5351C series serves as a functional alternative, though it requires additional software support. Ensure any substitute maintains the same 10-MSOP footprint and voltage compatibility.
