SI5350A-B02441-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5350A-B02441-GTR is a factory-programmed CMOS clock generator manufactured by Skyworks Solutions. 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 core supply voltage (VDD) of 1.8 V, 2.5 V, or 3.3 V and an output supply voltage (VDDO) of 1.8 V, 2.5 V, or 3.3 V. It accepts a 25 MHz or 27 MHz crystal reference and features glitchless frequency changes, configurable spread spectrum, and low period jitter typically below 70 ps pp.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the part number against the official Skyworks ordering guide to confirm the specific factory-programmed configuration. Ensure the package type matches the design requirements, as the Si5350A family includes 10-MSOP, 16-QFN, and 20-QFN variants. Confirm that the pre-programmed frequencies align with the target application specifications before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when replacing discrete crystals or oscillators in cost-sensitive designs requiring precise frequency synthesis. Choose based on the required number of outputs and package constraints. Verify that the input reference frequency matches the available 25 MHz or 27 MHz crystal options. Consider the power supply requirements for both the core and output buffers during system design.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The Si5350A belongs to the Si535x family of programmable clock generators. It is designed to replace multiple clock sources and crystal oscillators. The 'B' suffix indicates it is a factory-programmed variant, distinct from blank parts that require user programming via I2C or pins. This specific model is optimized for applications needing exact frequency synthesis without integer boundaries.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other factory-programmed Si5350A variants with different output counts or packages, such as Si5350A-Bxxxxx-GT (10-MSOP), Si5350A-Bxxxxx-GM1 (16-QFN), or Si5350A-Bxxxxx-GM (20-QFN). Ensure the replacement part has the identical programmed frequency plan.
