SI5340A-B03315-GMR

Overview

The SI5340A-B03315-GMR is a programmable clock generator from Skyworks Solutions, designed for ultra-low jitter applications. It features four outputs with frequencies up to 1.028 GHz and supports input frequencies up to 750 MHz. The device operates on supply voltages between 1.71 V and 3.47 V, consuming approximately 115 mA to 120 mA. It utilizes a QFN-44 package and offers output types including CML, HCSL, LVCMOS, LVDS, and LVPECL. The component exhibits a jitter of 90 fs and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports any-frequency generation across all four outputs
• Ultra-low jitter performance for precision timing
• MultiSynth technology for flexible configuration
• Multiple differential and single-ended output interface options

Applications

• High-speed data communication systems
• Telecommunications infrastructure equipment
• Enterprise storage arrays
• Test and measurement instruments

Procurement Notes

Verify the specific suffix 'GMR' indicates tape-and-reel packaging versus the standard 'GM' tray variant. Confirm the internal programming code 'B03315' matches the required frequency plan. Ensure compatibility with the Si5340-D-EVB development kit for initial validation. Check RoHS compliance status and moisture sensitivity levels prior to assembly.

Selection Notes

Select this model when four independent low-jitter clocks are required. Compare against SI5340A-D-GM if generic programmability suffices. Consider SI5341 series variants for higher channel counts. Evaluate power consumption requirements against the 115 mA typical draw. Verify voltage domain compatibility with system logic levels.

Part Context

This component belongs to the Si5340 family of silicon clock generators. It shares architectural similarities with the SI5340A-D-GM but differs in factory-programmed parameters. The family utilizes MultiSynth technology for high-performance jitter attenuation. It serves as a core timing solution for complex digital systems requiring precise clock distribution.

Replacement Considerations

SI5340A-D-GM serves as a generic alternative if custom programming is feasible. SI5340A-B03315-GM is the identical non-reel version for tray-based manufacturing. Cross-reference SI5341 devices for increased output channel requirements.
