The Silicon Labs Si5340 / Si5431 any frequency, any output clock generators combine a wide band PLL with a MultiSynth fractional synthesizer. Synthesize a wide range of integer and 33 non integer related frequencies. Each clock output can be assigned its own format and output voltage enabling it to replace multiple clock ICs and oscillators making it a true clock tree on a chip.
Si5340: 4 input, 4 output in a 44-Pin QFN package (7x7mm)
Si5341: 4 input, 10 output in a 64-Pin QFN package (9x9mm)
