SI5351A-B02783-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5351A-B02783-GT is a factory preprogrammed I2C programmable CMOS clock generator from the Si5351 family. It utilizes an internal oscillator with a fixed-frequency crystal reference (25 or 27 MHz) to generate up to eight free-running clocks. The device supports output frequencies ranging from 2.5 kHz to 200 MHz with zero ppm error. It features low period jitter, typically less than 70 ps peak-to-peak, 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 component is housed in a 10-pin MSOP package providing three LVCMOS outputs.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the B02783 suffix using ClockBuilder Pro software before integration. Confirm that the 10-MSOP package dimensions align with the target PCB land pattern. Ensure the external crystal matches the required 25 or 27 MHz specification for proper oscillator operation.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this variant when a fixed, factory-defined clock tree is required without field reprogramming. The Si5351A version is appropriate for designs needing only free-running clocks derived from an internal oscillator. Compare against Si5351B or Si5351C if VCXO tuning or external CLKIN synchronization is necessary for the application.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Skyworks Si5351 family of I2C-programmable clock generators. The 'A' designation indicates it uses an internal oscillator for free-running clock generation. The 'GT' suffix denotes the 10-MSOP package type with tube packaging. This series replaces discrete crystals, oscillators, and PLLs in embedded systems.

Clock Generators, PLLs, Frequency Synthesizers FAQ

What is the maximum output frequency supported by this device?

The device can generate output frequencies up to 200 MHz.

Does this component support synchronous clock generation?

No, the Si5351A variant generates free-running clocks using an internal oscillator. Synchronous generation requires the Si5351C variant with an external CLKIN input.

What is the typical period jitter performance?

The typical period jitter is less than 70 ps peak-to-peak.
