SI5340A-B04101-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5340A-B04101-GMR is a programmable clock generator from the Si5340 series, manufactured by Skyworks Solutions. 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 for surface mount installation, it functions reliably between -40°C and +85°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

This component is listed as obsolete or end-of-life. Availability is restricted, and distributors may not stock this specific part number. Verification of current lifecycle status and alternative sourcing channels is required before procurement planning.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when four low-jitter outputs are needed with frequencies under 1028 MHz. Ensure the design accommodates the QFN-44 package and SMD mounting style. Verify that the input frequency requirements do not exceed 750 MHz and that the operating temperature range fits the application environment.

Clock Generators, PLLs, Frequency Synthesizers Part Context

Part of the Si5340 family of Ultra Low-Jitter Clock Generators. This specific suffix indicates the reel packaging variant (GMR) compared to tray-packaged versions like SI5340A-D-GM. It shares core electrical specifications with other Si5340A variants but differs in packaging and potentially factory programming configurations.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional substitutes include other Si5340A variants such as SI5340A-D-GM, though packaging differences exist. Cross-model comparison with Si5341 series devices is possible if additional outputs are acceptable, but pinout and package changes must be evaluated.
