SI5351A-B06284-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5351A-B06284-GTR is a factory preprogrammed I2C programmable clock generator from Skyworks Solutions. It features three LVCMOS outputs and operates within a supply voltage range of 2.25 V to 3.6 V for the core and 1.71 V to 3.6 V for outputs. The device generates frequencies up to 200 MHz with 0 ppm error using an internal oscillator referenced by a 25 or 27 MHz crystal. Key electrical parameters include a typical period jitter of 70 ps, a maximum operating temperature of +85 °C, and a minimum of -40 °C. It utilizes a MultiSynth architecture for high-resolution fractional division.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming code B06284 matches the required frequency plan, as this suffix indicates a custom configuration. Confirm package type compatibility during sourcing. Check datasheet revision history for any updates to electrical specifications or pin definitions before finalizing procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a fixed-frequency solution is preferred over user-programmable variants. Ensure the design accommodates the MSOP-10 package constraints. Verify that the required output frequencies fall within the simultaneous unique frequency limits defined in the datasheet. Consider thermal resistance values if multiple outputs are active simultaneously.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5351 family of CMOS clock generators. The 'A' designation indicates it uses an internal oscillator without VCXO functionality. The 'Bxxxxx' suffix denotes a factory preprogrammed version, distinguishing it from blank user-programmable parts. It replaces discrete crystals, oscillators, and PLLs in embedded designs.

Clock Generators, PLLs, Frequency Synthesizers FAQ

What is the function of the B06284 suffix?

The B06284 suffix identifies a factory preprogrammed configuration generated via ClockBuilder Pro software, fixing the output frequencies at manufacture.

Can this device generate synchronous clocks?

No, the Si5351A variant relies on an internal oscillator and cannot synchronize to an external reference clock input like the Si5351C.

How does the device handle power supply sequencing?

All output supply voltages (VDDO) must be powered up either before or at the same time as the core supply voltage (VDD).
