SI5350A-B02895-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350A-B02895-GT is a factory-programmable 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 fixed-frequency crystal reference of 25 or 27 MHz and supports glitchless frequency changes, configurable spread spectrum, and static phase offsets. It features separate core (VDD) and output (VDDO) supply pins supporting 1.8 V, 2.5 V, or 3.3 V levels. The component is housed in a 10-MSOP package providing three LVCMOS outputs.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates multiple independent frequencies from a single crystal reference
• Supports glitchless frequency transitions and configurable spread spectrum for EMI reduction
• Features user-configurable control pins for power management and output enable functions
• Provides level translation via separate core and output voltage supplies

• Audio/video equipment and gaming consoles
• Printers, scanners, and projectors
• Residential gateways and networking communication devices
• Servers and storage systems

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory-programmed configuration associated with the B02895 suffix using ClockBuilder Pro software or the manufacturer's ordering guide. Confirm that the 10-MSOP package variant meets the required pin count and thermal constraints for the target PCB layout. Ensure the external crystal matches the 25 MHz or 27 MHz specification required by the programmed design.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a cost-effective replacement for multiple discrete crystals and oscillators is required. The 10-MSOP package limits the device to three outputs; choose larger packages if more channels are needed. Verify that the application requires pin-controlled configuration rather than I2C programmability, as this model lacks digital interfaces.

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 programming, the Si5350A relies on pre-programmed configurations accessed via GPIO pins. The -GT suffix indicates the 10-MSOP package type, distinguishing it from QFN variants that offer higher output counts.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350A variants with different output counts such as the 16-QFN or 20-QFN versions, provided the custom frequency plan is identical. Generic clock generators cannot replicate the exact 0 ppm synthesis without matching the specific MultiSynth divider settings.
