Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the exact suffix '53' against official Renesas documentation to confirm pinout, frequency settings, and package variations. Ensure compatibility with the required 3.15V-3.45V power domain. Check current availability status as clock synthesizers may have lifecycle changes. Confirm RoHS compliance and moisture sensitivity level requirements for your assembly process before ordering.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a 200MHz synchronous clock source with a 1:3 fan-out is required. It is appropriate for designs needing LVCMOS compatible outputs. Verify that the 8-SOIC package fits the PCB footprint constraints. Consider thermal management and supply voltage stability within the specified 3.15V-3.45V window during operation.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Renesas VersaClock family, which provides programmable clock solutions. The 343M series specifically targets low-cost, single-output or multi-output frequency synthesis needs. It utilizes PLL technology to generate stable clock signals from crystal or external clock inputs, replacing fixed-frequency oscillators in flexible system designs.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Consult Renesas datasheets for direct cross-references within the ICS343 or 343M series. Verify if variants like ICS343MPLF share identical electrical characteristics and pinouts. Ensure any substitute maintains the 1:3 ratio and 200MHz maximum frequency specification.
