SI5340A-B03499-GMR

Overview

The SI5340A-B03499-GMR is a programmable clock generator from Skyworks Solutions, part of the Si5340 series. It features four outputs with any-frequency capability up to 1.028 GHz and supports input frequencies up to 750 MHz. The device operates within a supply voltage range of 1.71 V to 3.47 V, typically utilizing 1.8 V or 3.3 V rails. It exhibits ultra-low jitter performance of 90 fs and consumes 115 mA to 120 mA of operating current. Housed in a QFN-44 package for surface mount installation, it functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports any-frequency output generation with maximum frequency below 1028 MHz
• Delivers ultra-low jitter performance specified at 90 fs
• Provides flexible output interface options including CML, HCSL, LVCMOS, LVDS, and LVPECL

Applications

• High-speed data communication systems requiring precise clocking
• Telecommunications infrastructure equipment
• Test and measurement instrumentation
• Networking switches and routers

Procurement Notes

Verify that the GMR suffix indicates a tape-and-reel packaging format rather than tray packaging when placing orders. Confirm compatibility with the specific development kit, such as the Si5340-D-EVB, for initial configuration. Ensure the selected variant matches the required output count and frequency specifications for the target application design.

Selection Notes

Select this component when a four-output programmable clock solution is required with ultra-low jitter characteristics. Compare against the standard GM version if reel packaging is preferred over trays. Consider the Si5341 series if more than four outputs are needed, noting the pinout and package differences between the QFN-44 and QFN-64 form factors.

Part Context

This part belongs to the Si5340 family of MultiSynth clock generators, designed for applications demanding high precision and flexibility. The family utilizes advanced PLL technology to synthesize various clock frequencies from a single reference. The SI5340A variant specifically targets high-performance digital systems requiring multiple synchronized clock domains with minimal phase noise.

Replacement Considerations

The SI5340A-B03499-GM serves as the tray-packaged equivalent of this reel-version component. For different output counts, consider the SI5341 series, though package and pin configurations differ significantly.
