Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix GMR indicates tape-and-reel packaging when sourcing. Confirm the exact frequency plan associated with the B05383 code, as this defines the internal register settings. Ensure compatibility with the required output voltage levels for your target application. Check current availability status as specialized clock generators may have limited stock or long lead times depending on the manufacturer's production schedule.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when designing systems that require flexible frequency synthesis across ten distinct lines without external dividers. The Si5341A variant is appropriate for applications needing output frequencies up to 1028 MHz, whereas lower frequency requirements might allow for cost-optimized alternatives. Consider the power consumption profile, which typically ranges between 115 mA and 120 mA, against your system's thermal constraints. Validate that the QFN-64 footprint fits your PCB layout guidelines.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5341 MultiSynth family of ultra-low jitter clock generators. These devices are designed to replace multiple discrete clock components, reducing board space and complexity. The family offers high integration by combining a phase-locked loop with multiple differential and single-ended output buffers. They are widely used in high-performance computing and networking environments where signal integrity is critical.
