Broadband infrastructures GENERAL DESCRIPTION
The AD9520-31 provides a multioutput clock distribution
function with subpicosecond jitter performance, along with an
on-chip PLL and VCO. The on-chip VCO tunes from 1.72 GHz
to 2.25 GHz. An external 3.3 V/5 V VCO/VCXO of up to 2.4 GHz
can also be used.
