Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against official Skyworks documentation to confirm tape and reel packaging requirements. Ensure the factory preprogrammed configuration matches the design specifications, as custom part numbers are assigned by the manufacturer. Confirm RoHS compliance status and lead times through authorized distributors prior to procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when low jitter performance is critical for synchronization applications. The Si5342 variant provides two outputs suitable for simpler clock tree designs compared to higher channel counts. Verify that the required output voltage levels (LVDS, LVPECL, LVCMOS, CML, HCSL) are supported by the specific output pins used. Use ClockBuilder Pro software to configure the device parameters.
