DESCRIPTION
The PL611s-26 is a general purpose frequency
synthesizer and a member of PhaseLink’s PicoPLL
TM
product family. Designed to fit in a small 6-pin DFN
or 6-pin SOT package for high performance
applications, the PL611s-26 offers very low phase
noise, jitter, and power consumption, while offering
up to 2 clock outputs.. The Frequency Switching
(FSEL) capability of PL611s-26 allows for
programming two sets of frequencies, while the
power down feature of PL611s-26, when activated,
allows the IC to consume less than 10 A of power.
PL611s-26’s programming flexibility allows
generating any output using Reference input signal.
