3. Functional Description
The Si5350A’s synthesis architecture consists of two high-frequency PLLs in addition to one high-resolution
fractional MultiSynth
Figure 2. This unique architecture allows the Si5350A to generate up to eight independent, non-integer-related
frequencies at any of its outputs. Each MultiSynth
a pin controlled glitchless frequency change at each output (CLK0 to CLK5).
