DESCRIPTION
The PL611s-15 is a low-cost general purpose
frequency synthesizer and a member of PhaseLink’s
PicoPLL
TM
Factory Programmable ‘Quick Turn Clock
(QTC)’ family. Designed to fit in a small SOT23,
SC70, or DFN package for high performance
applications, the PL611s-15 accepts low frequency
(>10KHz) Reference input and generates up to
200MHz output with the best phase noise, jitter
performance, and power consumption for handheld
devices and notebook applications. Cascading
PL611s-15 with other PicoPLL ICs could result in
producing all required system clocks with specific
savings in board space, power consumption, and
cost.
