SI5350C-B04473-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5350C-B04473-GTR 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, accepting reference inputs from 25/27 MHz crystals or 10–100 MHz external clocks.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming configuration associated with the B04473 suffix against the required system timing specifications. Confirm that the package type matches the design footprint requirements. Ensure the ordering information aligns with the intended reference clock input method and output count before finalizing procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a custom timing solution is required without I2C reprogramming capabilities. Choose based on the necessary number of outputs and the availability of pin-controlled features such as frequency select or spread spectrum enable. Verify compatibility with the available reference clock source, whether it be a crystal or an external clock signal.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5350 family of factory-programmable clock generators. Unlike the Si5351 series which supports I2C configuration, the Si5350C relies on pin-based control and pre-programmed data. It serves as a replacement for multiple discrete oscillators and PLLs in compact designs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350C variants with different factory programming codes but identical electrical characteristics. Ensure the substitute part supports the same output count and package type. Verify that the new part's pinout and control logic remain compatible with the existing board layout.
