DESCRIPTION
The PL611s-16 is a very low-power general purpose
frequency synthesizer and a member of PhaseLink’s
PicoPLL Factory Programmable ‘Quick Turn Clock
(QTC)’ family. Designed to fit in a small DFN, SC70,
or SOT23 package for high performance
applications, PL611s-16 accepts low frequency
(10KHz) Reference input and generates up to
54MHz output with the best phase noise, jitter
performance, and power consumption for handheld
devices and notebook applications. Cascading
PL611s-16 with other PicoPLL ICs could result in
producing all required system clocks with specific
savings in board space, power consumption, and
cost.
