DESCRIPTION
The PL611s-04 is a high performance low-cost general purpose frequency synthesizer and a member of
PhaseLink’s PicoPLL TM Factory Programmable ‘Quick Turn Clock (QTC)’. Designed to fit in a small
2.5mmx2.0mm oscillator module for high performance applications, the PL611s offers the best phase noise and
jitter performance, smallest die size, and power consumption of any comparable device. The power down feature
of PL611s, when activated, allows the IC to consume less than 10µA of power, while its programming flexibility
allows generating any output, using a low-cost crystal input.
