Additional Details:

The PL123S-09HSC-A3 uses a Phase-Locked Loop (PLL) to create output clocks from a crystal or external clock. The PLL facilitates frequency multiplication and division for a diverse selection of output frequencies. An integrated loop filter minimizes phase noise. Programmable settings enable precision adjustments to clock characteristics. Consult PhaseLink Corporation datasheets for electrical characteristics, timing, and appropriate usage. Proper decoupling capacitors near power pins help reduce noise. Datasheets also provide crystal parameter recommendations.

The '09HSC' likely refers to configuration and feature sets. 'A3' is a revision. Always consult the datasheet.
