Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering suffix when sourcing components. The 'MI' suffix indicates an MLF-16 package with Sn-Pb lead finish, while 'MG' denotes a Pb-Free variant with NiPdAu finish. Confirm whether tape and reel packaging (TR suffix) is required for automated assembly processes versus bulk tube quantities.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component for backplane retiming or signal retiming after long trace lengths where precise edge alignment is critical. Ensure the power supply matches the specific operating rating: 2.375V to 2.625V for 2.5V operation or 3.0V to 3.6V for 3.3V operation. Verify that the input logic levels are compatible with the internal termination network configuration.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The SY58052UMI belongs to Micrel’s Precision Edge® product family, designed for high-speed synchronization tasks. It functions as a data-to-clock resynchronizer, transferring data from the DATA input to the Q output at the rising edge of the CLK signal. This architecture makes it suitable for cleaning up uncertain timing from backplanes or transmission lines.
