SI5351A-B06168-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5351A-B06168-GTR is a factory preprogrammed I2C-configurable 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 0 ppm frequency synthesis error and operates within a core supply voltage range of 2.25 V to 3.6 V and output buffer voltages of 1.71 V to 3.6 V. It supports static phase offset, configurable spread spectrum, and glitchless frequency changes. The component is housed in a 10-MSOP package providing three independent outputs.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates multiple asynchronous clock frequencies using an internal oscillator and standard fixed-frequency crystals
• Provides exact frequency synthesis with zero parts-per-million error across all outputs
• Supports programmable rise/fall time control and adjustable output delay for signal integrity optimization

Clock Generators, PLLs, Frequency Synthesizers Applications

• Replacing discrete crystals, crystal oscillators, and fanout buffers in cost-sensitive designs
• Providing clock signals for audio/video equipment and gaming consoles
• Serving as a timing source for handheld instrumentation and laser range finders
• Supplying clocks for residential gateways and networking communication hardware

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogramming code associated with the suffix 'B06168' against the required system specifications before integration. Confirm that the 10-MSOP package variant meets the board layout constraints. Ensure the design accommodates the separate core and output supply voltage requirements defined in the datasheet.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when the application requires free-running asynchronous clocks derived from a standard 25 MHz or 27 MHz crystal without external synchronization. This model is suitable for designs needing precise frequency generation with low jitter but does not include the VCXO functionality found in the Si5351B variant. Verify that the maximum output frequency requirement does not exceed 200 MHz.

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 solely on an internal oscillator and crystal input, distinguishing it from the Si5351B which includes a VCXO and the Si5351C which supports an external CLKIN reference. The 'GTR' suffix denotes the tape and reel packaging format.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other factory preprogrammed variants within the Si5351A series, such as SI5351A-Bxxxxx-GT or SI5351A-Bxxxxx-GM1, provided the custom frequency configuration matches the system requirements.
