SI5350C-B03054-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B03054-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. The specific suffix indicates a tape-and-reel packaging format for the pre-configured unit.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the complete part number against official Skyworks documentation to ensure correct configuration parameters. Confirm that the GTR suffix matches the required reel quantity and handling specifications for your assembly line. Cross-reference the internal programming code to validate the specific frequency plan and pinout assignments before integration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a custom timing solution is required without the overhead of I2C configuration during runtime. Ensure the application requires pin-controlled features such as frequency select or spread spectrum enablement. Verify that the available package options meet the board space constraints and that the voltage levels align with the target system logic requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device belongs to the Si5350 family of programmable clock generators. It serves as a replacement for multiple discrete crystals, oscillators, and PLLs in complex electronic designs. The C variant specifically supports external clock inputs via the CLKIN pin, allowing for synchronous clock generation alongside free-running outputs derived from an onboard crystal.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other factory-programmed variants within the Si5350C series, such as SI5350C-Bxxxxx-GT or SI5350C-Bxxxxx-GM1, provided the electrical characteristics and package types are compatible. Ensure any substitute part has the identical internal configuration data to maintain system timing integrity.
