SI5351A-B02692-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5351A-B02692-GT is a factory preprogrammed I2C programmable CMOS clock generator from Skyworks Solutions. It utilizes an internal oscillator with a fixed-frequency crystal reference (25 or 27 MHz) to generate up to eight non-integer-related frequencies ranging from 2.5 kHz to 200 MHz. The device features three independent outputs in a 10-MSOP package, supporting exact frequency synthesis with 0 ppm error. Key electrical parameters include a core supply voltage of 2.25 V to 3.6 V and output buffer voltages selectable at 1.8 V, 2.5 V, or 3.3 V. It operates within an ambient temperature range of -40 °C to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the suffix B02692 against system requirements before procurement. Confirm that the 10-MSOP package meets board space constraints. Ensure the external crystal matches the specified 25 or 27 MHz reference frequency required by the Si5351A variant.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a fixed, preconfigured clock solution is preferred over user-programmable variants. The Si5351A variant is suitable for applications requiring only free-running clocks without VCXO or external CLKIN synchronization. Verify that the three-output capacity of the MSOP package aligns with the design's clock domain requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5351 family of I2C programmable clock generators. The 'A' designation indicates it relies on an internal oscillator and external crystal, distinguishing it from the 'B' (VCXO) and 'C' (CLKIN) versions. The 'GT' suffix denotes tube packaging for the 10-MSOP form factor.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements include other Si5351A variants such as SI5351A-B-GT for blank configurations. For higher output counts, consider the 16-QFN or 20-QFN packages within the same family.
