SI5340A-B04960-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5340A-B04960-GM is a programmable clock generator from the Si5340 series by Skyworks Solutions. It features four outputs capable of generating any frequency below 1028 MHz with ultra-low jitter performance, specified at 90 fs rms. The device operates within a supply voltage range of 1.71 V to 3.47 V and supports multiple output interface types including CML, HCSL, LVCMOS, LVDS, and LVPECL. Packaged in a QFN-44 format, it functions reliably across an industrial temperature range of -40°C to +85°C, consuming approximately 115 mA to 120 mA of operating current.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming code embedded in the suffix (B04960) against design requirements, as this variant contains fixed internal configuration parameters. Confirm package integrity upon receipt, as the component utilizes moisture-sensitive level packaging standards. Ensure ESD protection protocols are followed during handling due to the sensitive nature of the silicon substrate and fine-pitch QFN-44 terminals.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when fixed-frequency generation with ultra-low jitter is required without external programming overhead. Compare against the generic SI5340A-D-GM if reprogrammability is necessary for future design iterations. Verify that the 1.028 GHz maximum output frequency meets system bandwidth needs. Check compatibility with available development kits like the Si5340-D-EVB for initial validation if custom configurations were anticipated but are now locked.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5340 family of MultiSynth clock generators, designed for applications needing high-performance timing solutions. The 'B' suffix indicates a specific factory-programmed version, distinguishing it from user-programmable variants. It shares core architectural features with other Si5340 models but offers a turnkey solution for mass production environments where unique jitter profiles are standardized across the product line.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional substitutes include other factory-programmed variants within the Si5340A series, such as SI5340A-B05124-GM, provided their specific output frequencies match the design intent. For reprogrammable alternatives, the SI5340A-D-GM serves as a flexible option, though it requires external configuration tools. Always verify pin-to-pin compatibility and electrical specifications before swapping parts.
