SI5340A-B03284-GM

Overview

The SI5340A-B03284-GM is a programmable clock generator from the Si5340 series by Skyworks Solutions. It features four outputs capable of generating any frequency up to 1.028 GHz with an input frequency support up to 750 MHz. The device delivers ultra-low jitter performance, specified at 90 fs rms. It operates within a supply voltage range of 1.71 V to 3.47 V and supports multiple output logic types including CML, HCSL, LVCMOS, LVDS, and LVPECL. The component is housed in a QFN-44 package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Four differential or single-ended outputs supporting frequencies up to 1.028 GHz
• Ultra-low phase jitter specification of 90 fs rms
• Support for diverse output standards: CML, HCSL, LVCMOS, LVDS, LVPECL
• Wide-band PLL architecture enabling any-frequency, any-output configuration

Applications

• High-speed data communication systems requiring precise clocking
• Telecommunications infrastructure equipment
• Test and measurement instruments
• Industrial automation control systems

Procurement Notes

Verify the specific suffix B03284 against official Skyworks documentation to confirm the pre-programmed frequency plan. Confirm RoHS compliance status through the manufacturer's datasheet. Check for moisture sensitivity levels (MSL) requirements during storage and handling. Ensure the QFN-44 thermal pad connection is addressed in the PCB layout design.

Selection Notes

Select this model when four independent clock outputs are required with sub-100 fs jitter performance. Compare against the SI5341 series if ten outputs are needed instead of four. Verify that the 750 MHz maximum input frequency meets the reference clock source capabilities. Ensure the operating voltage range aligns with the system power rails.

Part Context

This part belongs to the Si5340 family of MultiSynth clock generators. It shares architectural similarities with the SI5341 but differs in output count. The 'GM' suffix typically indicates lead-free packaging. The 'B03284' code denotes a factory-programmed frequency set, distinguishing it from blank devices like the SI5340A-D-GM which require user programming.

Replacement Considerations

The SI5340A-D-GM serves as a programmable alternative if custom frequency generation is acceptable. For higher output counts, the SI5341 series may be considered. Verify pin-to-pin compatibility and electrical parameters before substituting.
