SI5350C-B03196-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B03196-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. This specific part number indicates a pre-configured unit in tape-and-reel packaging.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the factory-programmed configuration matches the required system frequencies before integration. Confirm that the GTR suffix aligns with the intended reel-based assembly process. Ensure the input crystal specifications or external clock parameters correspond to the programmed design. Validate that the package type and pinout are compatible with the target PCB layout.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a custom timing solution is required without the overhead of an I2C interface. The pin-programmable nature simplifies board design by removing digital control lines. Choose the 10-MSOP variant if three outputs suffice, or verify if higher output counts are needed. Ensure the application benefits from the low jitter and EMI reduction features provided by the internal PLLs.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device belongs to the Si5350 family of programmable clock generators. It serves as a direct replacement for multiple discrete oscillators, PLLs, and buffers. The 'B' designation typically refers to the specific silicon revision or feature set within the C-series lineup. It is designed to reduce bill-of-materials costs and board space in complex electronic systems.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other factory-programmed variants within the Si5350C series, such as SI5350C-Bxxxxx-GT. Verify that the substitute part has identical frequency programming and output configurations. Cross-reference package types to ensure mechanical compatibility.
