14-Output Clock Generator
AD9516-5
FEATURES 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 AD9516-51 provides a multi-output clock distribution function
with subpicosecond jitter performance, along with an on-chip PLL
that can be used with an external VCO/VCXO of up to 2.4 GHz.
The AD9516-5 emphasizes low jitter and phase noise to
maximize data converter performance, and it can benefit other
applications with demanding phase noise and jitter requirements. FUNCTIONAL BLOCK DIAGRAM
