SI5350A-B05941-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5350A-B05941-GM is a factory-programmable CMOS clock generator designed to replace discrete crystals and oscillators. It utilizes a PLL and MultiSynth architecture to generate up to eight non-integer-related frequencies ranging from 2.5 kHz to 200 MHz with 0 ppm error. The device operates on a fixed-frequency crystal reference of 25 or 27 MHz. It supports independent core (VDD) and output (VDDO) supply voltages of 1.8 V, 2.5 V, or 3.3 V. Key electrical characteristics include low period jitter under 70 ps typical, configurable spread spectrum for EMI reduction, and glitchless frequency changes.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming configuration associated with the B05941 suffix using ClockBuilder Pro software. Confirm that the required package type matches the design constraints, as the Si5350A family offers varying output counts across MSOP and QFN packages. Ensure the crystal load capacitance requirements align with the internal settings programmed into this specific part number.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a cost-sensitive solution requires replacing multiple discrete clock sources with a single programmable IC. Choose the Si5350A over I2C-programmable variants if pin-based control is preferred over digital interface configuration. Verify that the maximum output frequency and jitter specifications meet the target application's timing requirements before finalizing the design.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The SI5350A-B05941-GM belongs to the Si5350 family of clock generators manufactured by Skyworks Solutions. This family is characterized by its flexibility in generating custom clock signals without requiring external I2C controllers during operation. The 'B' series indicates factory pre-programmed configurations, distinguishing it from blank devices that require end-user programming.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include other Si5350A variants with different factory programming codes but identical functional specifications. When substituting, ensure the new part number supports the same number of outputs and package type. Verify that the replacement part's internal configuration matches the original system timing requirements.
