High performance wireless transceivers
ATE and high performance instrumentation GENERAL DESCRIPTION
The AD9517-3 1 provides a multi-output clock distribution
function with subpicosecond jitter performance, along with an
on-chip PLL and VCO. The on-chip VCO tunes from 1.75 GHz
to 2.25 GHz. Optionally, an external VCO/VCXO of up to
2.4 GHz can be used.
The AD9517-3 emphasizes low jitter and phase noise to
maximize data converter performance, and it can benefit other
applications with demanding phase noise and jitter requirements. Rev. E CP REFIN
