SI5351A-B06884-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5351A-B06884-GTR is a factory preprogrammed I2C programmable clock generator in a 10-MSOP package. It provides three CMOS outputs with a maximum frequency of 200 MHz and supports frequencies as low as 2.5 kHz. The device operates on a core supply voltage (VDD) of 2.5 V or 3.3 V, with an output buffer supply (VDDO) range of 1.71 V to 3.6 V. It utilizes a fixed-frequency crystal reference of 25 MHz or 27 MHz. Key electrical characteristics include a typical period jitter of 70 ps peak-to-peak and a maximum operating temperature of +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates up to eight non-integer-related frequencies using MultiSynth fractional dividers
• Configurable spread spectrum modulation selectable at each output
• Supports static phase offset and glitchless frequency changes
• Separate voltage supply pins provide level translation between core and output buffers

Clock Generators, PLLs, Frequency Synthesizers Applications

• XO replacement
• PCIE Gen 1 compatible systems
• Servers and storage equipment
• Networking and communication devices

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the suffix B06884 against the target design requirements. Confirm that the 10-MSOP package dimensions and pinout match the PCB footprint. Ensure the external crystal parameters align with the device's internal load capacitance settings.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this variant when a fixed, factory-defined clock configuration is required without field programming. The 10-MSOP package limits the device to three outputs. Verify that the application does not require the VCXO functionality found in the Si5351B version or the CLKIN synchronization of the Si5351C version.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5351 family of I2C-programmable clock generators. The 'A' designation indicates it uses an internal oscillator for free-running clocks only, distinguishing it from the VCXO-enabled Si5351B and the CLKIN-synchronized Si5351C. The 'GTR' suffix denotes tape-and-reel packaging for surface-mount assembly.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5351A variants in the 10-MSOP package, such as SI5351A-B-GT or SI5351A-Bxxxxx-GT, provided the preprogrammed frequencies are identical.
