SI5351A-B02057-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5351A-B02057-GT is a factory preprogrammed I2C programmable clock generator from Skyworks Solutions. It provides three LVCMOS outputs in a 10-MSOP package, generating non-integer-related frequencies from 2.5 kHz to 200 MHz with 0 ppm error. The device uses an external crystal reference (25 or 27 MHz) and operates on a core supply voltage of 2.25 V to 3.6 V. Typical period jitter is 70 ps peak-to-peak. It supports spread spectrum modulation and static phase offset.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates up to eight independent non-integer-related frequencies using MultiSynth fractional dividers
• Features highly linear VCXO architecture for precise frequency control
• Supports configurable spread spectrum at each output to minimize EMI
• Provides glitchless frequency changes and adjustable output delay

Clock Generators, PLLs, Frequency Synthesizers Applications

• Replacing crystals, crystal oscillators, and PLLs in cost-sensitive designs
• Audio/video equipment and gaming systems
• Printers, scanners, and projectors
• Handheld instrumentation and laser range finders
• Residential gateways and networking/communication devices

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the suffix B02057 against system requirements. Confirm that the XTAL-only input mode meets the design's synchronization needs. Ensure the 10-MSOP package dimensions align with the PCB layout constraints.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a fixed-frequency solution is required without field programming. Compare against SI5351B if internal VCXO tuning is needed, or SI5351C if external CLKIN synchronization is mandatory. Verify that the 3-output capacity suffices for the target application.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5351 family of I2C-programmable CMOS clock generators. It shares the MultiSynth architecture with other variants but differs in input capabilities and output counts. The 'A' designation indicates XTAL-only operation, while the 'GT' suffix specifies the 10-MSOP package type.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

SI5351A-B-GT serves as the blank version of this component. Direct substitution requires reprogramming via ClockBuilder Pro software unless the existing configuration matches the new design parameters.
