SI5351A-B06887-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5351A-B06887-GTR is a factory preprogrammed I2C programmable clock generator housed in a 10-MSOP package with three CMOS outputs. It operates on a core supply voltage of 2.25 V to 3.6 V and supports output voltages of 1.8 V, 2.5 V, or 3.3 V. The device generates frequencies from 2.5 kHz to 200 MHz using an external crystal reference (25 MHz or 27 MHz). Key electrical parameters include a typical period jitter of 70 ps peak-to-peak, a maximum input frequency of 27 MHz for the crystal, and a working temperature range of -40 °C to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• I2C user-definable configuration for generating non-integer-related frequencies
• Exact frequency synthesis at each output with zero ppm error
• Configurable spread spectrum selectable at each output
• Supports static phase offset and glitchless frequency changes

Clock Generators, PLLs, Frequency Synthesizers Applications

• XO replacement in cost-sensitive designs
• Networking and communication equipment
• Servers and storage systems

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogramming code associated with the suffix B06887 against the required system specifications. Confirm that the MSOP-10 package dimensions align with the target PCB footprint. Ensure the I2C pull-up voltages are compatible with the selected VDDO levels before finalizing the order.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this variant when a fixed-frequency solution is preferred over a blank programmable part. The Si5351A version utilizes only an XTAL reference, distinguishing it from the VCXO-enabled Si5351B or CLKIN-synchronized Si5351C. Verify that the 200 MHz maximum output frequency meets the design requirements for all connected loads.

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 external crystal oscillator for its reference source. The 'GTR' suffix denotes the tape-and-reel packaging format suitable for automated surface-mount assembly processes.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements within the same package and pinout include other Si5351A variants such as SI5351A-B-GT or SI5351A-Bxxxxx-GT. Note that generic blanks require custom programming, whereas this part arrives with factory-set configurations.
