Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming code B03612 against design requirements, as this suffix defines the fixed output frequencies and configurations. Confirm the GMR suffix indicates tape-and-reel packaging suitable for automated assembly processes. Ensure compatibility with the required I2C or SPI programming interface if field reconfiguration is needed, although this specific variant may be pre-configured.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when four distinct clock signals are required with frequencies up to 1.028 GHz. The 90 fs jitter performance makes it suitable for sensitive high-speed serial links. Compare against the SI5340A-D-GM if generic programmability is preferred over a fixed-frequency solution. Ensure the QFN-44 thermal pad requirements are met in the PCB layout for adequate heat dissipation during operation.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5340 family of ultra-low-jitter clock generators. It shares core architectural similarities with the SI5341 series but offers four outputs instead of ten. The device integrates a phase-locked loop (PLL) and multiple synthesizers to generate stable clock signals from a single reference input, replacing discrete oscillator solutions in complex system designs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The SI5340A-D-GM serves as a functional alternative within the same package, offering similar electrical characteristics but potentially different factory programming or packaging options. Verify pin-to-pin compatibility and output voltage levels before substitution.
