SI5351A-B02692-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5351A-B02692-GTR is a factory preprogrammed I2C-configurable CMOS clock generator from the Si5351 series. 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 error frequency synthesis, low output period jitter typically less than 70 ps peak-to-peak, and configurable spread spectrum capabilities. It operates on core supply voltages of 2.5 V or 3.3 V and supports separate output voltage levels of 1.8 V, 2.5 V, or 3.3 V.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogramming code '02692' against the required system specifications before integration. Confirm that the ordering suffix indicates the correct package type and tape-and-reel configuration for automated assembly processes.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this variant when a fixed set of clock frequencies is required without field reconfiguration. Ensure the design accommodates the 10-MSOP package footprint if utilizing the three-output version. Verify that the application does not require VCXO tuning or external CLKIN synchronization.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Skyworks 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 B and C variants which support VCXO and external clock inputs respectively.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other factory preprogrammed parts within the Si5351A series, such as SI5351A-Bxxxxx-GT or SI5351A-Bxxxxx-GM, provided the custom code matches the target frequency plan.
