SI5340A-B03285-GM

Overview

The SI5340A-B03285-GM is a programmable clock generator from Skyworks Solutions, part of the Si5340 series. It features four outputs capable of generating any frequency below 1028 MHz with ultra-low jitter of 90 fs. The device operates within a supply voltage range of 1.71 V to 3.47 V and supports multiple output types including CML, HCSL, LVCMOS, LVDS, and LVPECL. Packaged in a QFN-44 format, it functions between -40°C and +85°C with typical current consumption of 115 mA or 120 mA.

Procurement Notes

This component is listed as End-of-Life (EOL) by the manufacturer. Distribution channels indicate limited availability or discontinuation status. Verification of current stock levels and alternative sourcing strategies is required before procurement planning. Check official Skyworks documentation for final lifecycle status confirmation.

Selection Notes

Select this model when four low-jitter clock signals are needed with flexible output voltage standards. Ensure input frequency requirements do not exceed 750 MHz. Verify that the QFN-44 package fits the PCB layout constraints. Consider power supply stability within the 1.71 V to 3.47 V range during design.

Part Context

The SI5340A-B03285-GM belongs to the Si5340 family of silicon clock generators. It shares core architecture with other variants like SI5340A-D-GM but differs in specific configuration parameters defined by the suffix. The B03285 code indicates a factory-programmed frequency set.

Replacement Considerations

Direct functional substitutes may include other Si5340 variants such as SI5340A-D-GM if pin compatibility and electrical specs align. Verify output count and jitter specifications against application needs. No officially confirmed cross-reference part numbers are provided in the source data.
