The Si5324 accepts two input clocks rangingfrom 2 kHz to 710 MHz and generates two output clocks ranging from 2 kHzto 945 MHz and select frequencies to GHz. The two outputs are divideddown separately from a common source. The Si5324 can also use itsexternal reference as a Clock source for Frequency synthesis.

2 The deviceprovides virtually any Frequency translation combination across thisoperating range. The Si5324 input Clock Frequency and Clock multiplicationratio are programmable via an I2C or SPI interface. The Si5324 is based onSkyworks Solutions' 3rd-generation DSPLL technology, which providesany- Frequency synthesis and jitter attenuation in a highly integrated PLLsolution that eliminates the need for external VCXO and filter DSPLL loop bandwidth is digitally programmable, providing jitterperformance optimization at the application level. The Si5324 is ideal forproviding Clock multiplication and jitter attenuation in high performancetiming applications.
