AD9517-2 Data Sheet FUNCTIONAL BLOCK DIAGRAM APPLICATIONS
Low jitter, low phase noise clock distribution
10/40/100 Gb/sec networking line cards, including SONET,
Synchronous Ethernet, OTU2/3/4
Forward error correction (G.710)
Clocking high speed ADCs, DACs, DDSs, DDCs, DUCs, MxFEs
High performance wireless transceivers
ATE and high performance instrumentation GENERAL DESCRIPTION
The AD9517-2 1 provides a multi-output clock distribution
function with subpicosecond jitter performance, along with an onchip PLL and VCO. The on-chip VCO tunes from 2.05 GHz to
2.33 GHz. Optionally, an external VCO/VCXO of up to 2.4 GHz
can be used.
The AD9517-2 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
