SI5350C-B01989-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B01989-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, drawing a typical core current of 25 mA. The part number suffix 'GTR' indicates it is supplied in a tape and reel packaging format.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the specific ordering suffix matches the required package type and configuration. Confirm the factory-programmed parameters align with system timing requirements before deployment. Ensure the component is sourced from authorized distributors to guarantee authenticity and proper handling specifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a custom, factory-programmed solution is preferred over I2C programmable alternatives. Verify that the required number of outputs fits within the package constraints. Check if pin-controlled features like frequency select are necessary for the application design.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5350 family of clock generators. It serves as a replacement for multiple discrete crystals, oscillators, and PLLs. The 'C' variant specifically supports external reference clock inputs via the CLKIN pin, distinguishing it from variants limited to crystal-only references.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other factory-programmed parts from the Si5350 family such as SI5350A-Bxxxxx-GT or SI5350B-Bxxxxx-GT, provided they match the required output count and voltage levels.
