Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory programming parameters associated with the B01332 suffix against the official datasheet ordering guide. Confirm that the package type matches the required output count, as the Si5350C family offers distinct pin counts for different channel configurations. Ensure the design accommodates the specified supply voltage ranges and crystal requirements before finalizing procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a custom timing solution is required without I2C interface overhead. The pin-programmable nature suits applications where board space is limited and pre-defined frequencies are sufficient. Verify that the required number of outputs aligns with the available package options, such as the 10-MSOP for three outputs or the 20-QFN for eight outputs.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The SI5350C belongs to the Si535x family of clock generators manufactured by Skyworks Solutions. This series replaces discrete crystals, oscillators, and PLLs in compact designs. The 'C' variant specifically supports both crystal inputs and external clock references via the CLKIN pin, offering flexibility in synchronization domains compared to earlier versions.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other factory-programmed variants within the Si5350C family, such as SI5350C-Bxxxxx-GM or SI5350C-Bxxxxx-GM1, provided the output count and package footprint match the design constraints.
