SI5351A-B06148-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5351A-B06148-GT is a factory preprogrammed I2C-configurable CMOS clock generator from Skyworks Solutions. It utilizes an internal oscillator to generate up to eight free-running clocks, replacing discrete crystals and oscillators. The device supports output frequencies ranging from 2.5 kHz to 200 MHz with 0 ppm error using MultiSynth fractional dividers. It operates on core supply voltages of 2.5 V or 3.3 V and output buffer voltages of 1.8 V, 2.5 V, or 3.3 V. The component features low period jitter (typically <70 ps pp) and configurable spread spectrum capabilities.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the factory preprogrammed frequency settings against system requirements before integration. Confirm that the I2C address and register map match the host controller interface. Ensure power supply sequencing complies with datasheet recommendations to prevent latch-up during startup.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this variant when fixed-frequency outputs are required without field programming. Compare against SI5351B if voltage-controlled tuning is needed, or SI5351C if external reference synchronization is necessary. Verify package availability matches PCB footprint constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5351 family of I2C programmable clock generators. It specifically represents the 'A' version which relies solely on an internal crystal oscillator for free-running operation. The suffix indicates a factory preprogrammed configuration rather than a blank device.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other factory preprogrammed Si5351A variants such as SI5351A-Bxxxxx-GT. Generic replacements require reprogramming via ClockBuilder Pro software.
